Why are people concerned about COVID transmission in young people when they are statistically unlikely to have severe symptoms or be hospitalised or die? Look at other countries to see what may be coming...

Various authors have plotted cases vs age vs time. On the x axis is time, on the y axis are ages https://twitter.com/vincentglad/status/1303243869933404161. Look at time 531/532. Some incidence in 20-29 year olds. But in week 533, this spreads to 30-70 year olds. And then in week 535 and 536, cases in 70+

We have known this for some time. Here is the data for Florida from July https://twitter.com/zorinaq/status/1283189875341029376 Same thing. Starts with young people and spreads to older age groups

Here is the UK data for COVID mortality from @PHE_uk . Very few (but some) deaths in young people. So we may not see significant deaths filtering through for a few weeks

Chart (b) is the one to watch. These data lag by a couple of weeks https://www.gov.uk/government/publications/national-covid-19-surveillance-reports but I anticipate cases spreading up through the age pyramid in the next couple of weeks.
