COVID-19 Prevention Actions
There are many ways your actions can help protect you, your household, and your community from severe illness from COVID-19. CDC’s COVID-19 Community Levels provide information about the amount of severe illness in the community where you are located to help you decide when to take
Prevention Actions to Use at All COVID-19 Community Levels
In addition to basic health and hygiene practices, like handwashing, CDC recommends some prevention actions at all COVID-19 Community Levels, which include:
- Staying Up to Date with COVID-19 Vaccines
- Improving Ventilation
- Getting Tested for COVID-19 If Needed
- Following Recommendations for What to Do If You Have Been Exposed
- Staying Home If You Have Suspected or Confirmed COVID-19
- Seeking Treatment If You Have COVID-19 and Are at High Risk of Getting Very Sick
- Avoiding Contact with People Who Have Suspected or Confirmed COVID-19
Staying Up to Date with COVID-19 Vaccines
COVID-19 vaccines help your body develop protection from the virus that causes COVID-19. Although vaccinated people sometimes get infected with the virus that causes COVID-19, staying up to date on COVID-19 vaccines significantly lowers the risk of getting very sick, being hospitalized, or dying from COVID-19. CDC recommends that everyone who is eligible get a booster and stay up to date on their COVID-19 vaccines, especially people with weakened immune systems.
If you are moderately or severely immunocompromised or severely allergic to COVID-19 vaccines: Talk with a healthcare provider about whether you are eligible for a medicine called Evusheld that you can take before you are exposed to the virus. This medicine is a combination of two monoclonal antibodies provided together. Evusheld can help prevent infection from the virus that causes COVID-19 for 6 months. See additional information for making a COVID-19 plan to protect yourself from infection.
Improving Ventilation and Spending Time Outdoors
Improving ventilation (moving air into, out of, or within a room) and filtration (trapping particles on a filter to remove them from the air) can help prevent virus particles from accumulating in indoor air. Improving ventilation and filtration can help protect you from getting infected with and spreading the virus that causes COVID-19. Spending time outside when possible instead of inside can also help: Viral particles spread between people more readily indoors than outdoors.
Actions that can improve ventilation and filtration include:
- Bringing in as much outdoor air as possible—for example, opening windows.
- Increasing air filtration in your heating, ventilation, and air conditioning (HVAC) system, such as by changing filters frequently and using filters that are properly fitted and provide higher filtration.
- Using portable high-efficiency particulate air (HEPA) cleaners.
- Turning on exhaust fans and using other fans to improve air flow.
- Turning your thermostat to the “ON” position instead of “AUTO” to ensure your HVAC system provides continuous airflow and filtration.
