To your reply..yes and no. Might be best to describe it a splitting hairs I suppose but, there is no cure for this Bio weapon.
Some people are using the word “cure’ to imply a 100% effectiveness rate. This is no such treatment for any ailment nor has there ever been.
I agree that this is a bio-weapon. I believe it was released and spread intentionally by the Chinese (and other parties) to damage the US and specifically Trump. It was successful in that it did damage the economies of the US and many other countries. It was unsuccessful in that Trump still won the election.
