If the virus was deadlier than it is, I'd say it's way too soon to reopen businesses and so forth, but we're not talking about a virus that's as deadly as the one in the movie Contagion.
Well not at all, I saw that movie this year (though released in 2011) and
covid-19 pandemic just seemed to be reacting everything that was acted in that movie, except on a deadlier/fatal basis.The recovery rate worldwide is far higher than mortalities, that means the virus can be managed, and people can recover or also die, just the same possibilities with other diseases like Cancer, Tuberculosis, Cirrhosis etc. The reason why governments locked down their countries was cause of how fast the virus can spread. With the curve coming down in quite a lot of countries I don't see why they should not ease off the lockdowns.
The awareness has been created, everyone is now conscious of the presence of the virus. People have to go to work, businesses reopened and life reenacted again, the government locked down then as they tried to get a clue of what was going on, now that there are effective preventive measures, life must and should go on.
