The lockdown and containment in Chennai has proven to be ineffective, as skyrocketing numbers indicate.
The spiking numbers just indicate that the testing coverage has increased. The good part is the most of the cases in TN are reported to be asymptomatic and the death count here is very low (it is unlikely that the death count is massively fudged as it would have caused a controversy by now). Shops are open and vehicles are moving now. It is a good thing.
International borders were more or less open till the end of March, and markets in Chennai were functioning as usual during the lockdown. Common sense indicates that the virus has already spread wide and far BEFORE any lockdowns were imposed. The tests which started in full swing recently are just validating the spread.
As citizens, we need to ensure that we continue washing hands, wearing masks and sanitizing goods. But being terrified of something which is already at your doorstep doesn't help. There's no need for fear. Let's deal with this.
