Improving Ventilation in Your Home


Small particles that people breathe out can contain virus particles, including the virus that causes COVID-19. If a guest visits your home, improving ventilation (air flow) can help prevent virus particles from accumulating in the air.

Improving ventilation can help you reduce virus particles in your home and keep COVID-19 from spreading. You may or may not know if someone in your home or if a visitor to your home has COVID-19 or other respiratory viruses.

Ventilate your home by getting fresh air into your home, filtering the air that is there, and improving air flow. Good ventilation, along with other preventive actions, can help prevent you and others from getting and spreading COVID-19 and other respiratory viruses.

Use CDC’s Interactive Home Ventilation Tool to learn how you can decrease the level of COVID-19 virus particles during and after a guest visits your home.

COVID-19 Treatments and Medications


If you test positive for COVID-19 and are more likely to get very sick, treatments are available that can reduce your chances of hospitalization and death.

People who are more likely to get very sick include older adults (ages 50 years or more, with risk increasing with age), people who are unvaccinated, and people with certain medical conditions, such as chronic lung disease, heart disease, or a weakened immune system.


Medications to treat COVID-19 must be prescribed by a healthcare provider and started as soon as possible after diagnosis to be effective. The Treatment Locator (hhs.gov) can help you find a location that offers testing and treatment or a pharmacy where you can fill your prescription.

The combination of COVID-19, flu, and RSV could continue to stress the healthcare system this fall and winter.

As people start to travel and gather for the holidays, it’s vitally important that we protect ourselves and others from COVID-19 and all respiratory viruses.

COVID-19 Community Levels

CDC uses COVID-19 Community Levels to determine the disease’s impact on counties and recommend prevention measures.


CDC also tracks cases, laboratory tests, vaccinations, deaths, and other pandemic data and provides them on our COVID Data Tracker.
