How COVID-19 causes infection and strategies for prevention
|What COVID-19 does||What we can do|
|COVID-19 is an airborne disease.||Wear an effective mask!|
|COVID-19 binds to your cells to make more virus.||Get vaccinated to keep antibody levels high and
prevent COVID-19 from binding to your cells!
|COVID-19 uses your cells as “virus factories.”||Take sensible steps to avoid exposure to keep
COVID-19 out of your cells!
|COVID-19 does not care what happens to your body or anyone else’s!||Care about public health!|
Layers of defense minimize risk
No single COVID-19 safety measure is guaranteed to prevent infection. Each layer of protective measures we add lowers the risk of infection:
- Masks minimize the risk of transmission by capturing and redirecting the potentially contaminated aerosols produced as we breathe, talk, and eat.
- Physical distancing from others reduces the concentration of potentially contaminated aerosols and droplets that we share.
- Vaccination trains our bodies to defend themselves before we get infected, allowing us to mount an effective response upon infection.
- Ventilation and air filtration reduce the concentration of potentially contaminated aerosols in an enclosed space.
