Some people say we just have to get on with life, that previous generations just accepted risk and lived their lives.
We have to go back quite a long time to find a disease that was as lethal and easily transmitted and left a trial of chronically ill people in its wake. Maybe the so-called sweating sickness of the 15th century, which might have been a hantavirus.
Think about what life was like when they ‘just got on with it’. There were no indoor mass public gatherings, beyond perhaps a couple of hundred people. Schools were limited in number and usually very small. Most children worked. There were no large scale factories. People were constantly worried about disease, towns and villages were quarantined at the first sign of sickness. Households had to self isolate for 40 days if anyone became ill.
They did not carry on as normal, as we would understand it. They certainly did not have schools of 1,000+ pupils, offices and factories of thousands of people, football stadia, theatres for hundreds etc. All of these environments amplify transmission risk many fold.
According to the Zoe app, there are somewhere between 200 (1 in 5,000) and 2000 (1 in 500) cases per million depending on which part of the country you’re in. This feels about right because another approximation can be done on a national level. ONS says approximately 5,000 people are becoming infected per day. With 5.5 median incubation and 11.5 median clearance, one can estimate there are currently 85,000 infected people in UK or roughly 1 in every 780 people. So the Zoe data seems about right.
Using the Zoe data, one can calculate one’s odds of catching the virus in one’s local area. Where I live there are just over 300 cases per million, roughly 1 in 3,000. If a family of four are exposed to 1,000 people per day through work and 2 different schools, the raw odds of catching the virus is a third, ignoring any mitigation measure and more refined calculations. Those are not good odds for a risk taken on a daily basis. And as the virus spreads, the likelihood of catching it only increases.
With more and more evidence about the role children play in transmission, reopening schools with normal class sizes and without masks means parents, teachers and staff will have to accept there is a reasonably high chance they will catch the virus this winter.
