Health experts have generally advised people who are not sick that they don't need to wear a face mask unless they are caring for or in close contact with a sick person. As of March 31, the CDC has reportedly said it's reviewing this issue, but it has not issued any new recommendation.

Face masks are effective in preventing droplets from a sick person from infecting others and are used by healthcare providers, family members, and others when caring for or in close contact with a sick person. Handwashing and avoiding touching your face (eyes, nose, and mouth) are the most effective method of illness prevention.
