"Until Trump is defeated?" LOL.

Trump has nothing to do with this virus.  

He has shown to be an incompetent imbecile on the subject of pandemics.  It does not matter what he says or does.  
He should be ignored.

Americans should start wearing masks NOW or have 1M+ deaths by November, 2020, and 50M+ deaths by November 2021.

In the absence of a reliable vaccine, only a change in human behaviour (wearing PPE, social distancing) can stop the spread of this virus.
