So a pool in your backyard should be a-okay to splash around in — but take extra precaution if you head to a public area with a pool that other people are swimming in. As long as all of the chemicals and levels of that pool are where they should be, you don't have to worry about catching COVID-19 from the water. But in the summer, public pools are often packed. And if a mask-less person sneezes in your general vicinity while you're in a lounge chair nearby, that could be a problem.
