How COVID-19 Spreads

The virus that causes COVID-19 is spreading very easily and sustainably between people. In general, the more closely a person interacts with others and the longer that interaction, the higher the risk. People can spread the virus without even knowing that they are sick.

COVID-19 is spread in three main ways:

Breathing in air when close to an infected person who is exhaling small droplets and particles that contain the virus.
Having these small droplets and particles that contain virus land on the eyes, nose, or mouth, especially through splashes and sprays like a cough or sneeze.
Touching eyes, nose, or mouth with hands that have the virus on them.

Know the Risk

Avoid or limit your time where COVID-19 spreads more easily, especially if you aren't fully vaccinated:

Crowded places with many people nearby
Close-contact settings, especially with close-range conversations
Confined spaces with poor airflow

The risk increases the longer you spend in any of these settings and in places where these factors overlap. Click to learn more about safer social interactions.

Protecting Yourself & Others

The best ways to protect yourself from COVID-19:

Get vaccinated
If you aren’t vaccinated, keep six feet apart from others and wear a mask when you go out
Wash your hands often with soap and water or use a hand sanitizer that contains at least 60% alcohol
