vaccines and boosters

Vaccines lower the chance you will infect other people.

The main reason to get vaccinated and stay up to date with boosters is to protect yourself from serious illness. When you’re fully vaccinated and boosted, you’re less likely to get infected. And if you're not infected, you can't spread the disease to others.

masks

Masks help keep you from accidentally infecting others.

When people first get infected with COVID, they may not have any symptoms for a few days. Some people never get symptoms at all. That means you might have COVID and not know it. By wearing a mask, you not only protect yourself, you protect the people around you, too.

testing

Rapid tests tell if you have a lot of COVID virus right now, which might make you contagious to others.

When you know you might be contagious, you can make responsible choices about getting together with other people. But a test tells you only if you are infected at that moment. The longer it’s been since your last test, the more likely it is that things have changed. Knowing when you need to test is a critical part of living in a world with COVID. Knowing when testing is a good idea — even if it isn't strictly required — will keep your friends and family even safer.

Isolation and quarantine prevent you from infecting others.

Isolation and quarantine serve the same purpose — they help protect the public by preventing exposure to people who have or may have a contagious disease. When you know you have COVID, you need to isolate. When you've been in close contact with someone who has COVID, you may have to quarantine. Knowing what you have to do in those situations helps you keep your loved ones and your community safer.
