The jury is still out on schools - they have reopened in our area, but you only need one positive case in a school and automatically all pupils have to go into quarantine, or be tested. This has happened a couple of times in our area. It's known that children are more likely to have a mild or asymptomatic infection - but when they are symptomatic they shed the virus in similar quantities to adults, and can infect others in a similar way. Only 5% of all known cases in the EU. have been from people under 18 years of age - but allowing that schools can have up to a thousand pupils you only need one case and you're back to square one. The other problem is that these decisions are mostly made by people who have never been in a classroom with 30 kids - they talk about appropriate physical distancing and hygiene measures without realizing that these are impossible to uphold over an entire school day with a ratio of one teacher to 30+ children. It is imperative that schools hire extra staff for this in order to reduce class size but as long as they want to reopen under the present budgeting then it won't work.
