Your parents or guardians, brothers and sisters can visit you any time. You might also be able to have other visitors. But only if they’re old enough! Visitors have to be age 16 at least.
It’s important for visitors to wash their hands right when they come to see you. If they touched germs somewhere, a good washing will keep them from spreading them to you and others. So go ahead: remind them to wash those germs down the drain.
