It's called Covid-19 because the "19" is for the year 2019. Now think!!!! They knew about it since 2019 (maybe September 2019?)
The virus is a SARS type virus which is very well known since 1964, 60 years ago, when the Corona virus was first discovered in Scotland by woman scientist June Almeida.
It is known that this virus is contagious and can be fatal to some people.
What was done in 2019 about the Covid-19? By China? By WHO?
Yes, you guessed it: nothing. Not even trying to contain it in the place where it started, the Chinese city of Wuhan.
