The closer you are to someone who has COVID, the more of their breath reaches you.
The more of their breath you breathe in, the bigger the dose of virus you get.
We know now that COVID can travel a lot farther than 6 feet, especially indoors.
We also know it can stay in the air for a long time, especially in places without a lot of fresh air.
So, the longer you spend in a room with a person who has COVID, the more likely you are to breathe in enough virus to make you sick.
If you’re up to date on your vaccines, you're less likely to get infected. Remember that being up to date includes getting all recommended boosters.
If you're not infected, you can't spread the virus.
Washing your hands is a great way to help keep yourself from getting sick.
It's especially important to wash after you've been in a public place and before you eat.
Avoiding touching your eyes or nose helps, too. If you have virus on your hands, it can get into your body that way.
However, COVID infections usually come from breathing in air that has virus in it. That's why — for COVID — these tools are more important than hand-washing:
Staying away from places with lots of people.
Avoiding places that don't have a lot of fresh air.
