So I was on antibiotics which made me come out in a huge rash from head to toe. Servere allergic reaction and was told to go up. Whilst there, a couple with a child came in. Child with a few spots. Mum announced to everyone that daughters class had chickenpox last week with few being sent home. They'd brought child in just to "check" if it was chickenpox. Daughter seemed fine in herself. Low and behold she's seen and yes she has chickenpox. Now the whole waiting room (full of tiny babies) has been contaminated. If I'm being unreasonable then I apologise, but isn't this dangerous?? If a child's really ill with it then I completely understand but just to check?? Is this OK or AIBU?
