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.

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.

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

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.
