Some people who are infected may not have symptoms. For people who have symptoms, illness can range from mild to severe.
Adults 65 years and older and people of any age with underlying medical conditions are at higher risk for severe illness.
People ages 5 years and older should get COVID-19 vaccines to prevent getting and spreading the illness. Everyone ages 16 and older can get a booster shot.

Face Coverings Dos & Don’ts
CDC recommends wearing masks in public settings where other social distancing measures are difficult to maintain, such as grocery stores, pharmacies, and gas stations. Masks may slow the spread of the virus and help people who have the virus and do not know it from transmitting it to others.

Social Distancing
Social distancing, also called “physical distancing,” is one of the best ways to avoid being exposed to COVID-19 and slowing its spread. To practice social or physical distancing, stay at least 6 feet (about 2 arms’ length) from other people, do not gather in groups, stay out of crowded places, and avoid mass gatherings.
