It seems the CDC is still not recommending people wear face masks. Unless you have it. But then it goes on to say it is crucial to wear one if you are taking care of someone infected with COVID-19.
“Q: Does CDC recommend the use of facemask in the community to prevent COVID-19?
A: CDC does not recommend that people who are well wear a facemask to protect themselves from respiratory illnesses, including COVID-19. You should only wear a mask if a healthcare professional recommends it. A facemask should be used by people who have COVID-19 and are showing symptoms. This is to protect others from the risk of getting infected. The use of facemasks also is crucial for health workers and other people who are taking care of someone infected with COVID-19 in close settings (at home or in a health care facility).”
