The Center for Disease Control in the United States announced changes to guidelines for masking today. The CDC suggests masks don’t need to be worn for those who are vaccinated when walking, running, or biking outdoors with members of their household. Those who are vaccinated can attend a small outdoor gathering with fully vaccinated and people who are not vaccinated. Fully vaccinated people in the U.S. can also dine at an outdoor restaurant with friends from multiple households. Mask wearing must continue when attending a large outdoor event like a concert or football game. However, in the case of indoor activities, Americans, for the most part still have to wear masks.
