Here we have graphs (taken from the BBC) tracing the development of Covid-19 in the USA. This pandemic has been a casualty of American "Trumpian" politics!
For comparison, look at the graph for Spain where mask wearing is mandatory, All bars and restaurants have to close by 6pm, take-away is only allowed until 8pm, and travel outside a person's immediate area is punishable by massive fines.
Note how dramatically the numbers have dropped since the end of October! ie. in just one month!
