My coworkers laziness is beyond me

I work in a daycare and today hand foot and mouth has spread everywhere, a letter went out to parents and kids that had it got sent home. It's not in my class and I'm like well I don't want any of my kids getting sick. So I disinfect literally everything and wash everything and my coworkers don't even mop the floor. I know it's inevitable to keep anyone else from getting it but atleast you can try your best to keep the germs down. It just really bugged me.
