Most companies won't allow children of their employees to be there even if they are well. The insurance companies won't cover them if something happens. It is a huge liability, and I can't imagine that your supervisor doesn't know that. What if the bank got robbed? I know that's an extreme example, but it could happen. There could be a fire, anything that could cause the child harm. All of that is beside the fact that now, the supervisor faces having all of the employees come down with an illness, and being short handed. It's just plain stupidity on the supervisor's part.
Furthermore, it is childish for everyone to behave like school children; giving you dirty looks, and the "silent treatment". If I were you, I'd just continue to do my job, and be pleasant to everyone. If they continue to behave the way they are, go to your supervisor's boss or your human resources dept. My guess is that if HR knew about this, the supervisor would be reprimanded. Good luck.
