Don't use playgrounds
The CDC warns that it's not quite time yet to resume playing on playgrounds, even outdoor ones. For one thing, they can get more crowded than open areas, not to mention it's challenging to socially distance on a narrow bridge, platform, or staircase like those that playgrounds often have. For another, the surfaces on playgrounds can be challenging to clean and keep clean. And though the CDC has determined that the novel coronavirus doesn't spread as easily on surfaces as we originally thought, you'll still want to minimize your risk by avoiding contact with areas where you don't know how many people have touched it recently or the last time it was cleaned. Unfortunately, there are lots of coronavirus mysteries scientists still can't explain.
