Wear a mask
If you are not fully vaccinated and aged 2 or older, you should wear a mask in indoor public places.
In general, you do not need to wear a mask in outdoor settings.
In areas with high numbers of COVID-19 cases, consider wearing a mask in crowded outdoor settings and for activities with close contact with others who are not fully vaccinated.
If you are fully vaccinated and have a condition or are taking medications that weaken your immune system, you may need to keep taking steps to protect yourself, like wearing a mask. Talk to your healthcare provider about steps you can take to manage your health and risks.
