Am I wrong for being annoyed?

I have COVID and have to quarantine. I live with my grandparents. Well my aunt (moms sister) always brings her kids here so she can go out (she goes out every weekend and sometimes during the week) she always makes my grandma babysit even when she’s sick. Well I feel annoyed that they all know I have COVID but are still bringing their kids to my house and telling me “just stay away from my kids and don’t get them sick”. I feel like it’s so dumb having them here and they should just not go out if they can’t find another baby sitter. Am I wrong for thinking this? what if I accidentally give the kids COVID and their little bodies can’t handle it?
