Sorry Misiu, I think you are wrong and I stand by my statements. I am not even sure Covid-19 is a new virus. Respiratory panels do not even test for coronavirus, they do for flu possibly resulting in higher numbers.

The reason, it has not been contained is because many people likely have mild or no symptoms, the total number of cases is lilkely much higher than reported.
Could it be worse sure, but incidence of community spread with no known contacts suggests it is not.
