Ah, yes, washing your hands. The completely infallible way to prevent the spread of a disease.

I don't want you to be afraid - I want you to minimize the risk that you get coronavirus and become another infection vector, endangering the at-risk populations around you.

I want you to do that because it is the socially responsible thing to do, and it will decrease the chance of someone who is far more at risk of serious complications from the disease catching it.
