COVID-19 Basics

COVID-19, an illness caused by SARS-CoV-2, can spread easily from person to person. Current federal guidelines recommend that you wash your hands often, avoid close contact, cover your nose and mouth with a mask when indoors or around large groups of people, and get a COVID-19 vaccine when it’s available to you.

If you have symptoms of COVID-19, get tested and be sure to call your health care provider for medical advice.

Did You Know...

COVID-19 variants like Delta, Gamma, and Lambda develop when SARS-CoV-2, the COVID-19 virus, spreads from person to person and makes copies of itself.

COVID-19 tests and vaccines are free to anyone who needs them through a federal program.

Anyone, including children, can spread SARS-CoV-2, even when they have only mild symptoms or no symptoms at all — and especially if they have not received a COVID-19 vaccine.
