“To wear a face mask or not? The advice has been confusing. In China, Hong Kong, and Singapore, the general public has been encouraged to wear masks to prevent getting or spreading the novel coronavirus.

That could be changing. The Trump administration is expected to recommend that Americans in parts of the U.S. where the novel coronavirus is rapidly spreading wear cloth face masks or face coverings when in public to reduce transmission.”
For myself I think it’s a good idea. Here is the link to the face mask on Amazon
