The latest results from a random swab testing survey by the
Office for National Statistics (ONS) show that coronavirus infection levels among children aged 11 to 16
have risen slightly in England, with 0.43 per cent of secondary school age children testing positive in the week ending 20 March compared to 0.31 per cent the previous week.
LOCK IT DOWN, 0.12% IS HARD TO COPE WITH
I'm sure this ONS random testing is based on around 30,000 tests per month.
With schoolchildren these days we don't need to rely on such random testing for our data. In England, we're currently carrying out around 800,000 tests per
day in our schools, colleges and Universities, with students being tested twice a week. Our scientists will know exactly what the rate of infection is amongst our 11-16 yo's. something the New Scientist magazine will only have access to once that information is released to the public.
The good news is that all the positive test results from these extra 800k daily tests will have already been reported in the daily covid stats, and that the overall infection rates of the country continue to reduce, albeit at a much reduced rate, in spite of all the extra testing. I don't know the infection rate for this specific age group, but they did announce recently that there were 12000 positive tests across the school ages during the first 2 weeks of re-opening.
The very good news, is that the vast majority of these positive tests would have been asymptomatic, and they would all have casually continued going about their business whilst spreading the virus. But due to test trace and isolate, all of these students, and those they have come into contact with, will have been told to self isolate.
The upshot of all this is that they expected to see a small rise in student infections following the re-opening of schools, but that these would start to reduce again once the TTI system kicked in. So what we're seeing with the ONS results is somewhat expected, and I suppose it's reassuring that it appears the data taken from the ONS random sampling can be relied on to some extent.
