I believe once the testing in the U.S. begins the nation will be shocked to learn the virus is everywhere:widespread.Remember Xi allowed five million to leave Wuhan and make tracks to visit their relatives all around the world! Whatta guy! Since this was right before Chinese New Year and many had no,appreciable, symptoms to make them wary they continued on to their relatives that lived at a far distance.
I believe mutated into more transmissable forms and that now it will morph into a stronger and more permanent form which could continue for many years.It will be hard to kill:that only with drugs or a vaccine it will be a permanent yearly virus.
I hope to be wrong.This is my best guess.
