COVID-19 is a disease caused by a virus. Many people who have COVID-19 can have mild symptoms. Other people can have severe illness or die. Older adults or people with certain diseases, such as diabetes, have more risks related to COVID-19 than others.

The best protection against COVID-19 is to take the recommended vaccines to be up to date. You are considered up to date if you have received the updated Pfizer-BioNTech or Moderna COVID-19 vaccine.
