This is a balanced overview of the COV 19 event. Social distancing appears to have kept the worst at bay while we have built up resources to handle the worst. So far so good.
It may well have not been necessary. However, back of the envelope calculations suggest that actual deaths in Wuhan hit over 30,000 and they are not out of the woods yet. That is certainly supported by the reports on the ground. So yes we did need to stop this cold.
It is also true that distancing practise is also effective and we all get careful and do exactly as the japanese do with their face masks. This has worked in So korea and Taiwan rather well.
We are now trained to do just the same. we do need to get all those restaurants back to work at least and possibly those schools. After all schools are not randomly mixing and outside exposure can be avoided with masks.
