Masks Protect You & Me

Masks are an additional step to prevent people from getting and spreading COVID-19. They provide a barrier that keeps respiratory droplets from spreading. When we all wear masks, we take care of each other and everyone is protected.

For the most protection, take all these steps.


  • Wear a mask
  • Stay 6 feet apart
  • Avoid crowds and poorly ventilated places
  • Wash your hands

  • At least 10 days since symptoms first appeared AND
  • At least 24 hours with no fever without fever-reducing medication AND

COVID-19 in Children and Teens

While fewer children have been sick with COVID-19 compared to adults, children can be infected and get sick with COVID-19. Children can spread the virus that causes COVID-19 to others. The symptoms of COVID-19 are similar in adults and children and can look like other common illnesses, like colds, strep throat, or allergies. The most common symptoms of COVID-19 in children are fever and cough. Monitor your child daily for symptoms, keep track of who your child comes into close contact with. If your child gets sick, keep them home and call their healthcare provider.

Resources for Children and Teens, and Other Populations

According to a new CDC MMWR, since March, 277,285 COVID-19 cases in children have been reported. The rate of COVID-19 among adolescents aged 12–17 years was approximately twice that in children aged 5–11 years. Underlying health conditions were more common among school-aged children who experienced severe outcomes related to COVID-19.  In addition to K-12 schools and people age 15 to 21, CDC has developed one-stop shop toolkits for different populations with web resources, FAQs, posters, and other information.
