how covid spreads

Knowing more about COVID helps you make smart choices.

COVID moves through the air in tiny bits of moisture called aerosols from a contagious person. We release aerosols when we sneeze, cough, talk, or even breathe. You get COVID by breathing in aerosols that are carrying virus particles. The more virus you breathe in, the more likely you are to get sick.

vaccines and boosters

Vaccines reduce your risk of serious illness.

Vaccines are the most important way to protect yourself and others. Keeping up to date on your vaccines increases your protection. Vaccines sharply reduce your risk of going to the hospital or dying due to COVID. They also reduce your risk of getting long COVID. Right now, no cure for COVID works for everyone, every time. Staying up to date on your vaccines gives you the best chance to avoid getting infected at all.

masks

Masks help filter moisture carrying COVID from the air you breathe.

A mask that fits closely over your nose, mouth, and chin reduces the amount of virus you breathe in. If you're infected, it reduces the amount of virus you add to the air around you, where other people might breathe it in. If there’s a lot of COVID going around your area, wearing a mask will help protect you when:

  • You're indoors with people you don't live with.

  • You're outdoors in a crowd.

Any mask is better than no mask. Cloth masks give the least protection. Surgical masks are better if they fit well. KN95 or KF94 masks are really good, and N95 masks are the best.

sharing air

Social contact increases your risk of infection when COVID is spreading in your community.

If COVID infections are spreading in your community, being around people outside your household, especially indoors, is more risky. The more time you or other members of your household spend with others around other people, the higher your risk is. If fewer people in your area have COVID, then spending time with people outside your household is less of a risk.

testing

Testing lets you know if you're infected — so you can start treatment right away.

If you're at high risk of getting very sick from COVID, you need to know if you're infected as quickly as possible so you can start treatment. A few medications are available to treat COVID, but they have to be started very soon after symptoms begin.

If your immune system doesn't work, you can get treatment that will help keep you from getting very sick.

Certain diseases and medications keep the body's immune system from working properly. If your immune system can't do its job, COVID is much more likely to make you very sick or to kill you.   Unfortunately, because vaccines work by teaching the immune system how to respond to a virus, people with weak immune systems don't get as much protection from vaccines as other people do. If you're one of these folks, you can take medication that will help increase your protection from the virus. The protection should last for about six months.  You need a prescription to get this medication. If you don't have a doctor, call Combat COVID at 877-332-6585 for information and assistance.
