Only two percent of the deaths in Italy as of two days ago were under 60, only two deaths under 50yo. Italy has the second largest over 65 population in the world, and Lombardia is one of the older regions. Its going to be tough up there. But unlike the flu, which has already killed 84 children under the age of 4 in the USA this season, Corona had caused zero deaths under thirty in Italy. The records from the USA show that positive results from lab tests for flu run at over 20%, even in Italy the positive results are running at around 17% of tests.
Outside of Hubei province the fatality rate in China is under 1%, and given the apparently high incidence of asymptomatic cases is probably lower due to presentation bias in the case data.
Outside of Italy and Iran where controls were put in place quicker, the apparent fatality rate is around 1.3%, again, I suspect it will drop under 1% and possibly signficantly under 1% the longer the episode runs and the presentation bias is mitigated over time.
If you are over 65 or have an underlying condition, take steps to minimise exposure, if you under 65 the fatality risk may be less than the flu, if you are under 30 it is almost certainly less than the flu. In Italy only 2% of all cases presented in the 0-18yo demographic. That is remarkably low compared to the flu.
Australia's three fatalities to date fit the demographic, the gentleman from the cruise ship was I believe late 70's with underlying conditions and the other two were residents in the same old peoples home in NSW.
So if you are stockpilng toilet paper, and you are under 50, why don't you put on a face mask and give them to an elderly neighbor to save them a trip to the shops and the risk of exposure. It is in this demographic that case development needs to be slowed because the development of critical symptoms and fatality rates seems to be an order of magnitude higher than for over 70's than under 50's.
