People aged 2 years and older who are not vaccinated should wear a face covering when indoors.
When outdoors, masks are generally not needed unless you are in a crowded setting.
Even if they are vaccinated, people with weakened immune systems may still be at risk and should wear a mask indoors.
Masks should be worn indoors in public in high transmission areas.
Masks that cover your nose and mouth are required to be worn on planes, busses, trains, and other public transportation when traveling into, within, or out of the United States.
Stay six feet away from others (social distancing) especially if you are at high risk.
If you test positive, you should isolate. The CDC now recommends a five-day isolation period, followed by five days of mask-wearing when around others.
