How about HIV? No public health emergency declarations, with related public health measures such as quarantine and lots of public notification of how it spreads, was declared. This was to be politically correct and not offensive to the homosexual community.
As a result, many innocent people, such as hemophiliacs, became infected, suffered, and died.
With this so-called novel coronavirus, I think they knew it existed much sooner than the general public was informed, hence the name 19, as in 2019.. They didn't bother to tell the public until 2020.
An immediate quarantine should have been put into place. Immediate, far-reaching,
and long-lasting. Until a vaccine is developed.
I think there might already be a vaccine.
There has probably been a test for quite a long time before the public has had access to it. Trump and those near him have testing EVERY SINGLE DAY, if he can be believed.
It will be interesting to see if the Russian vax works.
