Nathan Cleary not fined, but the five women were fined.

I thought it was interesting to read that Nathan Cleary was not fined recently for a gathering at his home, whereas the five women concerned were fined.

https://www.news.com.au/sport/nrl/nrl-investigating-after-new-videos-of-nathan-cleary-emerge-phil-gould-reacts/news-story/96b4fee28b60e79a243e8db5a136a2b1

The reason given by police was that house belonged to Nathan Cleary. The legislation in Victoria, if I read it correctly, would have meant Nathan Cleary would have been fined if this occurred in Victoria. I decided to read the legislation to see how the legislation in NSW and Victoria differ.

You can find NSW's legislation at the following location.

Public Health (COVID-19 Restrictions on Gathering and Movement) Order 2020

You can find Victoria's legislation as the following location.

Stay at Home Directions (No 4)

Where the legislation differs for this situation is the legislation for Victoria clearly puts the responsibility for not letting people into their home on the resident, whereas for NSW, there's no such restriction. You can find the relevant section in the Stay at Home Directions (No 4) in Part 4, Section 11, Point 3. "During the stay at home period, a person must not permit another person to enter the premises as which they ordinarily reside, unless:", and the activity Nathan Clearly participated in wouldn't have come under the list of exemptions.

I find the differences between the laws interesting as I would not have thought that would be the case. Yes differences for some localisation, but not in overall principle. This really does show that if you're gaining information from the media, you need to pay particular attention to which state the story is about.

Car Versus Public Transport cost comparison has moved.

About a year ago I wrote the Car Versus Public Transport calculator to enable people to easily compare the cost of using a car versus the cost of taking public transport.

For a couple of reasons I've decided to merge the Car Versus Public Transport with the Car Running Cost Calculator. By merging the two calculators it will make it easier for people to find the Car Versus Public Transport calculator. In  addition, since it's necessary to first work out how much it costs per kilometre to use your car, the Car Running Cost Calculator is now more easily accessed from the Car Versus Public Transport calculator.

Notes: 

It should be noted this is the residential address when the case was notified and not necessarily the current residential address or the location where the infection occurred. Cases with an overseas address have not been included. Cases with an interstate address are not included. Cases with an unknown address are not included. It is felt these will be resolved and included later in the relevant location.

Travel ban from Italy may have changed the course of the coronavirus in Australia.

At the time and now also looking back, I must admit I was quite annoyed the government didn't move quickly on the travel ban from Italy. It almost felt like the ban was being delayed due to the Melbourne 2020 Grand Prix. Whether it was or not will only be known by the government but perhaps in years to come we may find out.

Thank goodness a team member was infected otherwise the Melbourne Grand Prix would have gone ahead and who knows what level of infection would have occurred.

I think this is where the government got it wrong. If the government used its modelling now and went back and made the decision to ban travel from Italy and implement tighter quarantine measures it would be interesting to see how much the curve would have been reduced. It may even be that we'd have eliminated the virus now.

The huge impact of the Ruby Princess on NSW would likely not have occurred if the bans were started earlier. With an extra week of travel bans the passengers would have no left the ship in such an uncontrolled manner.

The following article appeared on the 11th of March 2020.

https://www.smh.com.au/sport/formula-one-narrowly-escapes-australian-travel-ban-on-italy-20200311-p54918.html

I remember it was frustrating at the time. Add that Scott Morrison was still talking about attending his beloved Sharks NRL match, it appeared he was either keeping up appearances for Australians, or just didn't get it at that stage.

https://www.smh.com.au/sport/formula-one-narrowly-escapes-australian-travel-ban-on-italy-20200311-p54918.html

Thankfully that changed and the government caught up to where they needed to be.

The quarantining of everyone coming into Australia into hotels is where we needed to get to. Asking people to self-isolate just doesn't work because of the nature of a portion of the people. I couldn't help feeling that one thing the government could have done was to compensate people for having their liberty taken away from them. It was necessary for them to be quarantined but it's almost like they were doing the community services. They'd done nothing wrong.

The one thing I feel the government is still doing wrong is not providing the valuable raw data that lets us know what is really going on. Victoria did this for a while. We were informed where infected people had been and we could make sure this had no impact on us. Then all of a sudden the Victorian government stopped providing the information. That to me means something is being hidden from all of us.

Could the governments of Australia do better. Absolutely. However in my mind they've done very well and I'm thankful for the efforts. I'm thankful for those who have been quarantined in hotels. I'm thankful for the many people around me who really are making a considerable effort to self isolate and social distance.

Thank you.

Strange coincidences. Tom Hanks and Rita Wilson.

Ever thought a coincidence you just discovered was so amazing you just had to share it? OK. I thought I'd share a couple of recent coincidences that came about because of the coronavirus.

The first was I was trying to work out the timeline for when Richard Wilkins was infected with the coronavirus. The following is the timelines I could ascertain from the media and other online sources.

Rita Wilson live at Sydney Opera House
Saturday 7 March from 8pm
Richard Wilkins meets Rita after the performance.

Rita attended Channel Nine Sydney studio on Monday 9 March.

Monday 16 March 7 News article
https://7news.com.au/lifestyle/health-wellbeing/richard-wilkins-tests-positive-to-covid-19-c-746279
Richard Wilkins tests positive

Monday 23 March - Richard Wilkins Facebook account
Day 12 of quarantine still positive. - Indicates self quarantined on possibly Friday 13 March
Tested positive 9 days ago - Indicates tested positive result Monday 16 March as per news article.

Now for those who don't know, Rita Wilson is Tom Hanks wife.

The coincidence. Does anyone recall the name Tom Hanks character (Chuck Norland) gave to his companion, a volleyball, in the 2000 movie, Cast Away.

Yes. Tom Hanks volleyball companion was called Wilson.

The name reportedly came about because the volleyball was made by Wilson Sporting Goods.

I couldn't help feeling there may have been a little chuckle about Tom Hanks wife's last name also being Wilson.

As a final point, if you watch a video of Tom Hanks throwing the volleyball, you'll notice his fingers are quite wide apart. The fingers which become Wilson's hair are close together.


More recently I was saying the word influencer and influenza and couldn't help feeling with my rather slack pronunciation, the two words sound very, very similar. Even their meanings are close, one who spreads the word and one that spreads.

If there's such a thing as a good outcome with the coronavirus, social distancing is affecting the number of laboratory counts of influenza, which as the following article states, is down from 11,159 in March 2019 to 5,435 in March 2020, and that can only be a good thing.

https://www.newcastleherald.com.au/story/6715247/cold-coughs-flu-and-fever-are-tracking-down-with-increased-social-distancing/

I thought I'd share in case others had experienced such coincidences and thought they were worth sharing.

Is a vaccine the only way out with the coronavirus?

Over the past weeks I've read of many things such as herd immunity, flattening the curve, etc, but the one thing I keep reading is the only way out with the coronavirus is for a vaccine to be developed.

I can't help feeling this may be wrong. Why? Because I think back to the recent past. Where's SARS now? Where's the Swine Flu? Where's the Aussie Flu? They're gone. Once the virus runs it's course it's gone. Perhaps they evolve, but basically from the general populations point of view they're gone.

Whilst we did move slower at closing the borders than I feel we should have, and perhaps slower at isolating people returning from overseas instead of relying on people to self isolate at home (which we know human nature means some won't), but overall I feel we've got there.

We need to social distance as a community because there's pockets in our community where the infection exists and there's no way to know where those pockets are until an outbreak occurs.

In time however, if we persist with social distancing and isolation strategies I'm hopeful the virus will die out. Then we need to keep the borders closed until the virus dies out overseas as well.

The one thing I feel that is missing is useful data that lets us know where the public exposure locations are happening right now, each day as the authorities find out. Then we can see if we've been exposed in any of those locations and minimise our chances of infecting others.

Yes the government is providing data daily, but it's what I'd call useless data. It's data that's counting things that's happened, not data that helps us.

Each day in Victoria there's now a relatively small number of new cases of coronavirus. Each of those cases is a person who has recently visited a number of places. All each state government needs to do is to make that raw data available and others will present the data in a form that's useful to the general public. Each day in each state there's potentially only a few dozen to perhaps the low hundreds of data points. If we have access to that data we can then use applications that track where we've been to see if we were at or near any of the public exposure locations. We could at the simplest level just check an online map each day.

My real concern is governments are going to look at technology to track all of us, and frankly that's not the type of data I'd be confident they'd use in ways we'd be happy with. I know where I've been, my car's dashcam lets me know and I'm sure we can all find apps to track our location without providing the data to large organisations that want to mine that data for other reasons. All I need to know is the public exposure locations and I have what I need for myself, my family and my friends. That means everyone who wishes to, would have what they need too.

If I felt I'd been in a public exposure location I'd closely monitor my health for anything unexpected. I'd self isolate (within 5 days there's 95% certainty you've not been infected) and I'm sure the majority of other people would as well.

Right now we have no real data. When we walk out on the street, go to the shops, go to work, we don't know anything about who has been infected around us. What shops they've visited, what trains or buses they've taken, nothing. This creates fear and uncertainty and that brings out the worst in people.

At the moment the state governments are not sharing the public exposure location data. That's a pity. Yet really there's also one other group that could change that tomorrow. Those who are infected. They could easily share the locations they've visited.

Unless we have data really the only thing we can do is assume everywhere is a risk. Every shop, every food establishment, every petrol station. Yet if you think about it, that's absurd. There's only a few dozen or less new cases in each state each day. That's a fairly small number of public exposure locations each day and knowing those locations, would give everyone peace of mind.

Dettol as a hand sanitiser for novel coronavirus COVID-19

I was chatting to a friend and he mentioned his wife made him up some hand sanitiser. I'd previously noted people using disinfectants and thought I'd share what I knew, as he knew less.

With a few questions I determined his wife had made up his hand sanitiser using Dettol.

In terms of Dettol being effective against the novel coronavirus they makers can’t yet say because the strain of coronavirus virus is so new.

The Dettol site says it should be based on past experience with the group of viruses called coronavirus, but can’t yet say without testing for the novel coronavirus (COVID-19).

At this point in time I’d stick with the known recommendation of using an alcohol based sanitiser just to err on the side of caution.

https://www.dettol.co.uk/about-us/understanding-coronavirus/

The following article explains why the Dettol packaging can refer to coronavirus before the outbreak of the novel coronavirus.

https://www.aap.com.au/dettol-effective-against-known-strains-not-2019-novel-coronavirus/

The World Health Organisation has issued a publication for location production of "handrub", although the recipe is for large quantities.

There you go, now you know what I know. Hope it helps in some way.

Red light speed camera at St Kilda Road and Union Street. A Whirlpool user's question.

I read a person's question on Whirlpool where they went through a red light (where there's a red light camera) and was wondering if they would be getting booked.

https://forums.whirlpool.net.au/thread/3lyzj649

As I understand the person's situation is they were"

  • Travelling southbound in the service road on St Kilda Road where it crosses Union Road.
  • There's a speed camera for the service road and another for the main road.
  • The person was travelling under the speed limit but sped up once they realised the light was changing to amber. By speeding up they increased their speed to around 55-57km/h so under the speed limit.
  • The traffic light changed to amber when they were 5-10 metres from the stop line.
  • They think the back half of their car was going through the intersection when it turned red.
  • The person did a U-turn to the main road section of St Kilda Road, did a left turn from the main road crossing the service lane.

There's a couple of points of interest here.

First, if the person really was 5-10m from the stop line could they have been able to stop in time before entering the intersection. There's an additional 8m after the stop line before the intersection. At 5-10m if they were travelling say 50km/h their stopping distance would have been 15m and so they would have been over the stop line but it would have been quite close to decide.

If they continued at 50km/h they would have travelled 55 metres in four seconds, (the timing for the amber light), plus another 6.9 metres for the roughly half second allowed once the light changes to red. In other words there was plenty of time to continue at their current speed and not get booked.

If you can stop before the stop line you should. If you think you'll go over the stop line but not into the intersection (over the pedestrian crossing for example) and can stop you should. If you don't think your can fully enter the intersection with all of your car before the light turns red then you should stop or there's a high probability you'll get caught by the red light camera. Only keep going if it's not safe to stop, in which case there's sufficient time allowed in the amber and red light timing of the traffic signals.

Remember, with the sensors one is often after the stop line so to be clear of the sensor you need to have all of your car past the sensor before the light has turned red. Yes there is about half a second allowance in the red phase, but this is such a short amount of time. Think of this as being about the length of the car.

Keep mind if you're travelling slower due to turning or traffic, you cover less distance. Many people get booked because they're travelling slowly. When you're travelling slowly keep in mind it takes less time to stop.

People often slow down as they approach speed cameras through fear of getting booked. This actually can increase their chances of getting fined because at a slower speed, they can take longer to pass over the sensor.

Most of us can't estimate distance well. If we could life would be much easier. Without some aid on the road we're all likely to continue to misjudge the distance and time with the subsequent fine for misjudging things.

For example, this person thought they were 5-10 metres from the stop line. They also said the back of their car was probably still in the intersection when the light went red. From the stop line to the traffic lights on the other side of the intersection is approximately 25-28 metres.  If he was 10 metres before the stop line plus say 2 metres from the front of his car to where he's sitting, that's around 37-40 metres. The amber shows for 4 seconds and at 50km/h he would have travelled 55 metres. That is he would have been past the traffic lights and not been able to see them. That means he was probably further before the stop line than he thought and mostly likely had sufficient time to stop but decided to speed up instead.

Now as for the U-turn and turning left from the main road across the service lane, there's a no left turn sign at the intersection so that was breaking the law.

Coronavirus social distancing rules: Can I go and visit a family member? Directions - Stay At Home

I'm starting to get quite concerned by our state becoming a "police state". Yes we have to social distance, yes we have to stop the coronavirus from spreading, but I'm sure most of us have seen on the news people being booked for what none of us would think is fair. Those that don't get their story on the media end up paying. Those that get airtime have their fine withdrawn.

https://www.theage.com.au/national/victoria/no-fines-for-people-in-shops-as-car-wash-penalty-revoked-20200410-p54ix7.html

Our government needs to make sure they don't push too far or their hard work to date will start unravelling. People aren't stupid. If the government of Queensland can get the population of the state out to vote with no noticeable impact on the level of virus infections, people will start questioning the government if they become too heavy handed. As population we are all doing our best in difficult times.

https://drive.google.com/open?id=1_DcJvl566YOBOx-QOUJdTV-u_cSi6r9mf5wV3RRS3iQ

If by running the council elections in Queensland there was the actual real possibility of mass spreading of the virus this would have occurred within 14 days of the election. The table shows 12 days and there rate of infections has actually dropped. There isn't a noticeable change in infections resulting from millions of people going out to vote.

As to the question of, "Can I go and visit a family member?", this wasn't clear so I decided to see what I could find. The ABC's website provides the answer which hopefully gives people peace-of-mind. Then if the police pull you over you can provide the information provided by the Prime Minister and clarified by the ABC. Although who really knows what each state and individual police force, or even individual police officer decide on how to implement the law. If you get fined going to court is likely to be costly and cost result in even more expense and possibly jail time. That's not the type of threat we should be living our lives under.

https://www.abc.net.au/news/2020-03-29/scott-morrison-coronavirus-covid19-two-person-rule-explained/12101212

In particular the statement in the section titled, "Can I go and visit a family member?"

A family split across two houses can meet, so you can go and visit your parents or a sibling — although common sense probably ought to be used, and the usual social-distancing protocols should also be employed.

Unfortunately the world is a little crazy at the moment. Hopefully things will calm down.

Update: 11/04/2020
After reading the news article on the man washing his car in a car wash at 1 am in the morning, I couldn't help feel that recording any interaction with the police at this time is a wise idea.

Update: 12/04/2020
In terms of "Can I go and visit a family member", the following is a link to the Victorian Government's stay at home direction. There's no mention of visiting parents or a sibling. This really does show how the Federal Government is saying one thing, the ABC is supposedly clarifying things for us, but in the end, we really have no clue. The police can have a field day fining people because the gotcha is "ignorance of the law is no excuse".
https://www.dhhs.vic.gov.au/direction-stay-home-no3-signed
What appears to be important here is Part 4, Section 11, Point 3. You must not let others into your home except for the reasons listed. Family and siblings is not listed. The answer then is no.

Update: 15/04/2020
The Directions - Stay At Home No 3 expired on the 13th of April. It took some time to locate the new directions which can be found on this page.
https://www.dhhs.vic.gov.au/state-emergency

The new Directions - Stay At Home No 4 now expire on the 11th of May.

The BBC headline - Are coronavirus tests flawed?

I started to think with people being isolated (thousands in hotels), and some of those people being doctors and possibly other medical staff, why can't they test to see if these people are positive or not after perhaps 3-5 days. Then if people prove to be negative they can go on to assist others.

I can't be sure, but it probably all revolves around the word prove.

I've been trying to find articles that would let me know the minimum time it takes for a person with the coronavirus to test positive. I really haven't found anything that I'd call conclusive, if anything, I've found more articles indicating problems with tests or testing. The headline for the following article was Are coronavirus tests flawed?

https://www.bbc.com/news/health-51491763

From reading the article I realised the following:

Coronavirus is a respiratory virus. That means our breathing system.

The tests currently performed using a swab is taken at the back of the throat and nasal passage. If it's too early in the person's infection the same may not be sufficient.

If the person isn't coughing this may reduce the amount of sample in the area being tested.

The person doing the testing may not be sampling sufficiently.

No test is 100% perfect

This following article and particularly at the end where they state the structure of testing is the tests are 95% specific and 95% sensitive helps us to understand that out of 100 people, 5 people may be positive for coronavirus even though they test negative. When we're talking about thousands,  tens of thousand of tests and possibly hundreds of thousands of test, that's potentially tens of thousand of tests not picking up a person is actually positive for coronavirus.

https://www.washingtonpost.com/science/2020/03/26/negative-coronavirus-test-result-doesnt-always-mean-you-arent-infected/

As I read more I start to understand the science is not perfect and for this reason we need to be more cautious, to be isolated longer to be more confident, social distance further, to err on the side of caution for our own good.

Australian coronavirus (COVID-19) current situation and case numbers.

Whilst the data I'm recording relating to coronavirus is for Victoria, sometimes it's good to be able to see the information for all of Australia. I decided to look for this information and found the following government site.

https://www.health.gov.au/news/health-alerts/novel-coronavirus-2019-ncov-health-alert/coronavirus-covid-19-current-situation-and-case-numbers

For me the main number I'm looking for is the locally acquired cases where there's been no direct link to someone coming into the country or a contact of a person coming into the country.

Currently for Australia that figure is around 9.3% of cases.

Had the government moved more quickly to close our borders and isolate those coming into Australia, the total number I suspect would be have been less. I tend to think in the scheme of things that's an easier task. Not easy, but easier. This has been done thank goodness. Before this too many people coming into the country infected their contacts and others. The contacts are easier to identify, but not the others. Others that they wouldn't know they connected with.

Ultimately had the government moved more quickly the local community infection should have been lower, or in an ideal world almost nonexistent, but it's impossible to lock down everything.

To me it's the locally acquired cases that are important. The government talks about flattening the curve but this is relatively easy once the borders are closed and those coming in are in mandatory isolated. The curve will flatten, however the figure to watch is the locally acquired cases.

If the locally acquired cases grow what we'll see is the curve will naturally start to flatten fairly quickly, but then the curve will start to increase again. That is what we really have to watch.

It's hard to imagine the internal lock down, social distancing and what some people would call "the police state" situation is necessary, but if those locally acquired cases increase, that's the probably the main option to slow the curve down.

What's missing for us who like to know more is to know who is included in the locally acquired cases where the contact is not identified. For example do doctors and nurses who are dealing with multiple cases fall into this category? It would be nice to have more information. The more information we have the better decisions we can make.

Disinfecting for the coronavirus

We have a commercial grade disinfectant product that can be used to disinfect benches, door handles, etc. I started to wonder whether or not this disinfectant product was really suitable for coronavirus. I have a science degree (haven't used it) so keep in mind I'm not an expert of any type.

When I went to the website for the product I was actually quite surprised. The product made no mention of being effective at disinfecting against viruses. Yes bacteria and pathogens, but no mention of any of the common virus (such as influenza) so effectively using the product I feel is a waste of time, at least for the coronavirus.

It's important that you just don't go out and purchase products thinking they're helping. Make sure the information on the packaging mentions viruses or you could just be wasting your money or worse, not protecting your family even though you're making the effort.

I found this page which I thought was useful. I'd be reluctant to use bleach (call me a chicken) but I did learn not to use bleach and other household products that are acidic. Phew. Didn't know that.


Basically the page is telling us to use an alcohol based product.

I also found what the airlines were doing quite interesting. 


Certainly you can see they're making the extra effort to deep clean. Now I do understand the plane uses operating theatre grade filters to filter the air, but a plane isn't an operating theatre with a single patient. There's lots of moving people that are around you and going past you and they're breathing and they can get close. The main take from the article however is the type of products they're using.

All I did really was since I had some doubt about the product, was to  perform a search on the product, found the manufacturers website, read the information and there was no mention of the product being suitable for viruses. Keep in mind there may be restrictions on companies by the government in putting such claims on the products, such as extensive testing that isn't worth the time and resources for the company.

What proportion of people infected with the coronavirus do not show symptoms?

One of the main problems with the coronavirus is when people first get infected it takes a while before the symptoms show, but a bigger problem is those who are infected with the coronavirus but do not appear to show any symptoms, which is known as asymptomatic.

The following article shares quite a bit of information and through various articles we can estimate those infected but not showing symptoms could be from 17.9% up to 50%. That's one fifth to half of all infected people.

https://www.abc.net.au/news/2020-04-04/covid-19-coronavirus-without-symptoms-still-contagious/12119942

That's why it's very important for people to self isolate for 14 days, although it does make you wonder how many of the people who self isolate really fully self isolate for the 14 days. In the first instance they had to get home somehow if they were travelling. Then if like the rest of us, you come home with nothing in the pantry or fridge, I'd suspect many picked up supplies. It's just the nature of people.

As an example the below article it states there around 100 Australian doctors and dentists on a cruise.

https://www.theguardian.com/world/2020/mar/17/coronavirus-covid-19-australian-doctors-dentists-stuck-cruise-ship-coast-chile

According to the following article there were a group of 120 medical professionals.

https://www.abc.net.au/news/2020-03-28/coronavirus-covid-19-cruise-ship-doctors-angry-over-quarantine/12099604

Now this is where we should forget these are medical people and just say people. There were 77 people who were taken to a hotel for isolation. When police later returned 33 had left the hotel, or roughly 43%.

That's just what people do. Were they infected, we don't know. Was there a risk, probably.

This however does show us that if a third to a half of the people are asymptomatic it's important for them to full self isolate.

Although I do wonder why people in this situation can't be tested after a number of days and if they are not infected, continue on their way. Possibly because there's a shortage of test kits.

I thought the following was an interesting example of people lying about their symptoms so they could see their doctor face-to-face. However many people who say they don't have symptoms actually do! That would certainly affect the statistics if people are lying either intentionally, or simply because the ailments are minor. I know as I get older I have symptoms of things and I just put it down to age.

Update: 4/04/2020
A police check of 391 returned travellers resulted in 99 of them not being at home. That's a around 25% of people at the time of the check were breaching the self isolation. This would indicate a much higher percentage breach the self isolation. This probably one of the reasons the government now has people self isolate in hotels.

With coronavirus is it safer to go to a holiday house or stay at home?

There's many people who are going to smaller towns thinking they're safer. What the country and smaller towns don't realise is they generally have infected people in their area. So really, is the holiday house any safer than being at home. The answer depends and in many cases, it might not be. Make sure you think things through.

I decided to get the coronavirus cases data for the 2nd of March for the Local Government Areas across Victoria. Yes there are less people in regional areas, but it's not really the number of cases that's important, it's the number of cases per head of population. Some regional areas will actually have more infections per head of population than some city areas.

For example, I live in Manningham. There's 17 cases of coronavirus for a population of 125,508 (2018 population statistics) meaning there's 13.5 cases per 100,000 people. Now if I had a holiday house in the Mornington Peninsula, would I consider it safer to go to the holiday house. Most people would think so. However if you look at the data there's been 29.5 cases per 1000. That's over double the number of cases and the way I look at that, twice the chance of coming into contact with someone who is infected.

In addition I have a lot of choices around me from milk bars, petrol stations, small grocery shops to the majors where I can buy goods and services. In the holiday regions everyone goes to the same place. There's really not that much choice. If something goes wrong the medical facilities are often quite limited.

The following is a link to the table I created which shows for each Local Government Area, the number of cases, the population and the number of cases per 100,000 people.


So before you head off thinking you're improving your safety perhaps check the numbers. Do you really want to go to an area where the risk is greater? Knowing the numbers means you can make a better decision for you and your family.

Half of people with coronavirus show no symptoms.

Research in Iceland shows that half of the people with coronavirus show no symptoms.

https://www.news.com.au/lifestyle/health/health-problems/coronavirus-symptoms-half-of-infected-people-show-no-signs-of-virus/news-story/8557a0b5e5142a3a6cb9b5f926ea6e91

I've read somewhere (I could be recalling incorrectly) that some people just get symptoms of an upset stomach. Perhaps it's worth keeping this in mind.

If half the people don't show symptoms this is another reason we should all start thinking about wearing masks whilst out in the public. It is a way for each of us to protect others should we be infected by don't know it.

The following article had the headline New Yorkers urged to wear masks in public.

News.com.au article on those who have died from coronavirus and where they were infected.

It saddens me to think of the people dying from the coronavirus. Nothing could be worse. I find writing this post difficult for that reason. My thoughts go out to the families.

Today I read that of those who have died three quarters can be traced back to three sources, cruise ships, aged care home and hospitals.

https://www.news.com.au/lifestyle/health/health-problems/coronavirus-australia-threequarters-of-deaths-linked-to-cruise-ships-aged-care-home-and-hospitals/news-story/9fce1be8d3cf7904ceaea35d932b80ba

For me this level of detailed reporting helps answer question and is appreciated. Sometimes if information is not made available to the general public it creates confusion and concern. With more information we're better placed to understand what is happening around us.

Coronavirus, to wear a mask or not wear a mask. DIY option if masks are sold out.

I thought I'd share a couple of articles which influence me as to whether or not to wear a mask.

The first is a study which was about a person in China who was infected and went on what sounds like a bigger long distance bus. The article shows that other people on the bus got infected, but those wearing a mask did not get infected. If should be kept in mind this may just be luck. Not everyone not wearing a mask got infected either.

https://www.dailymail.co.uk/news/article-8094933/How-one-man-spread-coronavirus-NINE-people-bus.html

The one thing to keep in mind is the government has two roles. Two look after the people and to look after the economy. We however have one role and that is to look after ourselves and our families, whilst at the same time doing our best to look after others. Sometimes what the government does may conflict with what we should do.

For example if everyone were to wear a mask then there wouldn't be enough masks to go around and those that really need to wear masks, such as health workers who risk their lives to look after us, may not be able to access the masks they need. The government needs to look after health workers first and foremost. Without them and keeping them healthy means the rest of us are at greater risk. Therein lies and conflict. You need to make a decision for yourself.

More recently this article about the CDC (Center for Disease Control in America) has started to reconsider the advice given to the general public on the use of masks.

https://www.nytimes.com/2020/03/31/health/cdc-masks-coronavirus.html

Finally, if you do wear a mask it is extremely important to educate yourself on the correct way of wearing and using a mask. If is possible that with incorrect usage you may in fact increase your risk of infection. For example letting the mask drop below you face once out of a crowded area to breath means your are keeping the surface of the mask near your face, and that isn't a good idea. Not correctly sanitising your hands when putting on or taking of your mask may increase your risk.

Another article I read was about making your own masks. What was good about the article was there was some scientific type research on the materials to use. So even if you can't buy a mask, you can always make it yourself, or have a friend with sewing skills make it for you.

https://smartairfilters.com/en/blog/best-materials-make-diy-face-mask-virus/

Do keep in mind making your own mask should be a last resort. But if it helps to reduce the chances of infection by half, then that's still better than no protection. Interestingly it may be that a mask helps you stop touching your face more and that's also a good thing.

One thing that is apparent is if you are ill that it's a good idea to wear of mask for the benefit of others. If you are not showing signs of coronavirus (called asymptomatic) then you could be spreading the virus. Wearing a mask reduces the risk to others. If others wear a mask too that reduces the risk to you.

For me it makes sense to wear a mask in public. Remove the mask carefully and make sure I correctly sanitise my hands.

Update: 3/04/2020
It appears the tide is starting to turn with regards to people being advised to wear masks. Lots of information in this article.
https://7news.com.au/lifestyle/health-wellbeing/coronavirus-update-asia-may-have-been-right-all-along-about-coronavirus-and-face-masks-c-948214

CDC (in the USA) have updated their recommendation to now use cloth face covering.
https://www.cdc.gov/coronavirus/2019-ncov/prevent-getting-sick/cloth-face-cover.html

Knowing the codes used to name face masks can be confusing. The following has a table which gives the different codes. In Australia P2 is the equivalent of the USA code N95.

Update: 24/04/2020
In the following study, if I read the discussion correctly, in the situation of an infected child with a virus in a household, if the others in the household adhere to wearing a mask whilst in the presence of the infected person, the can reduce the risk of being infected by 60-80%.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2662657/#R27

The following article relates to Health Care Workers wearing N95 masks with a 62% reduced risk of bacterial infection compared with wearing no mask.
http://www.isg.org.au/index.php/news-items/study-shows-superiority-of-n95-respirators-in-protecting-health-workers-against-bacterial-respiratory-infections./

Update: 28/05/2020
The following articles show how effective different masks are when tested. Even surgical masks which don't fit that well performed reasonably. In all cases the risk was at least halved and in some cases nearly 20 time less. That's a significant reduction.

Update: 24/08/2020
In the following article I found the information that wearing masks increases the percentage of people being asymptomatic both good and concerning. Good because people are getting less affect, but bad because having more people asymptomatic means more people may spread the virus because they don't think they're sick.



Story shared by Melbourne doctor shows how infectious coronavirus can be.

I thought I'd share this article. A doctor in Melbourne  was at a gathering with 12 friends. Later one of those friends tested positive for coronavirus. Since then all but one have tested positive for coronavirus including the doctor.

Hands, washing hands by Neil Diamond. Sung to the tune of Sweet Caroline.

I thought I'd share the video from Neil Diamond, where he's adapted Sweet Caroline to be more relevant in the time of coronavirus.

https://youtu.be/sPLgsV_Ms3Q

I've always enjoyed Neil Diamond's songs and thank him for adding value to my life through his music.

My one regret. At uni I was passing a room where there was a singer with a guitar sitting on a chair in the middle of a very large room, with a large crowd of people around him. I think everyone was sitting on the floor so it didn't look particularly comfortable. It didn't seem that interesting. I recalled later that singer was most likely Neil Diamond. Perhaps someone was pulling my leg, but I really do regret I didn't stop and listen to a great entertainer.

Person wondering if there was any chance of getting out of a red light camera fine.

I found an interesting question on the Whirlpool forum today from a person wondering if there was any chance of getting out of a red light camera fine. The quick answer is generally no.

https://forums.whirlpool.net.au/archive/32krv6j9

However I found this intersection to be quite interesting. It took me a while to understand what had happened.

The person was travelling in Surrey Hills NSW, along Foveaux Street turning right into Crown Street. The right turn lane is a dedicated lane for right turning cars. The lights for going straight ahead were green, but there was a red right turn arrow.

If you look at the traffic lights you'll see a stack arrangement of four lights. I've not seen four vertical lights like this in Victoria. The top light it appears is the turn arrow light.

Secondly there's no oncoming traffic as this is a one-way street. In Victoria I've not seen a right turn arrow where there's no traffic coming towards you. Perhaps there is one, but I can't recall one.

The driver in this case noticed the pedestrian walk sign was green but there was no one on the pedestrian crossing. This would indicate the turn arrow may either be timed, or pedestrian activated.

In this case the driver didn't know the right turn arrow was red as their visor was down and this blocked their view of the top turn light.

The obvious lesson here is you need to make sure you can see all traffic lights and make sure your vision is not obscured by your visor. It's also a good reminder to Victorian drivers that some traffic lights in NSW are pedestrian activated.

One things this also shows is the limitation of the traffic light technology. If it is the case that a pedestrian pressed the button to activate the red right turn arrow, but decided to move on and not cross the road, then the pedestrian has impacted the flow of the traffic and a fine has been issued where there zero chance of a safety risk to anyone. In effect the driver has been fine in a situation where there was not safety risk. Ultimately however if a driver doesn't obey the traffic lights, no matter how absurd they've been designed, they are disobeying the law.

In this case a simple and costly mistake by the driver.

Stay at home directions by the CHO (Chief Health Officer) of Victoria

I'm the type of person who likes to learn the rules of what we are supposed to do or not do. That applies to most things in my life but particularly in times such as now with the coronavirus. In effect I like to be a good citizen.

Even then if I think things can be done better, without conflicting with the government's rules, then I'll take that action as well.

We often joke about one person's parenting style to their child. Their catch-phrase statement was "learn the rules, obey the rules". Perhaps now we have to all behave a little like children and learn the rules and obey the rules. This isn't just for our own benefit, but for the benefit of the community as a whole. If you disobey the rules then think about the thousands of others who are also disobeying the rules. That behaviour even though individually doesn't appear to make much difference, multiply it out by thousands and it can and will make a significant difference. Remember, we are all in this together.

So if you're interested in the rules, in effect the laws currently in place, the following is worth reading.
