It is very difficult, even with detailled track & trace, to be sure where any individual was infected,
except probably for some published studies of particular superspreader events
We can only examine risks for particular occupations and age groups
All countries show an absolutely tiny % of deaths among children, even smaller risk for the under-10s
increasing risk from middle age and rapidly accelerated risk from age 60
Teachers have not so far shown up statistically as having a higher risk than the population average,
either from pt schools, or from the limited number of countries so far with ft schools
Note that pt schools happened when many other workers were WFH or furloughed, i.e. at lowest risk.
The ONS did not find teachers to be at increased risk, as an occupation
and Germany had only 7 staff deaths from > 1 million employed in schools, childcare etc which I calculated before to be roughly average risk for their age group.
Age is absolutely the dominant risk factor
and all but the more serious health conditions are less of an additional risk than being up to 10 years older
In the UK, someone aged 45+ infected with COVID doubles their risk that year of dying from all causes.
Advice in many countries is that age 60+ should take extra care,
so a combination of 60+ with health conditions does indicate WFH should be considered if possible, especially for men.
The total of 35 COVID deaths for age 0-40 in Germany, a population of 83 million, plus a further 78 deaths for 41-50,
illustrates that (at least with a high quality health service and efficient track & trace to enable early health moitoring)
COVID is only a tiny death risk for the young & middle aged, even with health conditions
- although it is admittedly too early to quantify longterm effects for survivors, it seems 5-10% of confirmed cases may have these.
