Coronavirus Disease 2019

The FAQ about COVID-19 variants will be updated as experts at the Centers for Disease Control and Prevention (CDC) share more information. Check the CDC’s COVID-19 webpage often for updates.

Viruses change through mutation often. When a virus has one or more mutations it is called a variant. New variants are expected to occur and become more diverse. Sometimes new variants show up and go away. Other times, they last for longer periods of time.

COVID-19 has some variants that allow it to spread more easily. Experts monitor the spread of all COVID-19 variants. To learn more about the COVID-19 variants being tracked, visit the CDC’s About Variants of the Virus that Causes COVID-19 webpage.

COVID-19 spreads when an infected person breathes out droplets and very small particles that have the virus in them. These droplets and particles can be breathed in by other people or land in their eyes, nose or mouth. They can also land on surfaces and be spread through touch.

The CDC has more details on how COVID-19 spreads.

Flu and COVID-19 are both respiratory illnesses that spread easily, but they are caused by different viruses. COVID-19 is an infection caused by the coronavirus (SARS-CoV-2). Flu is an infection caused by the flu virus (influenza viruses). Because some of the symptoms of flu and COVID-19 are similar, it may be hard to tell the difference between them based on symptoms alone.
