Re: reasons not to close schools...
Getting people to just act sensibly over a long period is much easier than a lockdown, and although the overall number of people who catch it will be about the same the peak will be spread out, to levels where the NHS can cope.
If you want to stop a virus spreading, you have to stop people spreading it. Doing absolutely nothing apart from suggesting people wash their hands a bit more (or for some people, suggesting that they wash their hands) doesn't really cut it.
Remember, it's a virus. You can't "cure" it. Sooner or later we all need to catch it, or be vaccinated against it, those are the only ways to stop the spread. It takes 6-9 months minimum to develop a vaccine, so it needs to be managed at a low level until then. Lockdown won't work, as France and Italy will discover.
How come Asian countries which locked down are now getting on top of it then?
'Do not let this fire burn': WHO warns Europe over coronavirus
Tedros stressed that countries should take a comprehensive approach. “Not testing alone,” he said. “Not contact tracing alone. Not quarantine alone. Not social distancing alone. Do it all. Find, isolate, test and treat every case, to break the chains of transmission … Do not just let this fire burn.”
The British government's response - actively choosing to stop community testing, deciding not to even bother trying to trace people who might have come into someone diagnosed with Covid-19, allowing people to behave as usual, is wrong-headed, irresponsible, and a complete contradiction of WHO guidelines and the opposite of what Asian countries have done.
