About COVID

COVID is an infectious disease caused by a virus that infects the lungs and breathing passages, such as the nose, mouth, and throat. It can cause mild to severe respiratory illness, including dry cough, shortness of breath, fatigue, fever, diarrhea, head and body aches, and loss of taste and/or smell.
 

Who is most at risk for COVID?

Anyone can get COVID. People at increased risk of severe COVID illness and complications, including hospitalization and even death, include: People ages 65 years or older, those who are unvaccinated or not up to date on their COVID vaccinations, and people with certain medical conditions.

How does COVID spread?

A person with COVID can spread the virus when they cough, sneeze, or speak with others from a close distance. COVID is more likely to spread in poorly ventilated areas and crowded indoor settings. Less commonly, you can also catch COVID if you touch a surface contaminated with the virus and then touch your eyes, nose, or mouth.
 

How is COVID prevented?

Staying up to date with the latest COVID vaccine is the most effective and safe way to prevent severe illness, hospitalization, or death due to COVID infection.

What should I do if I have COVID symptoms?

COVID symptoms mimic symptoms of the flu and other viruses. Anyone with COVID symptoms should get tested.
