My experience of chicken pox (admittedly only 2 kids and one of them was only 10 weeks when he had it) is that you have a couple of days of fever and general viral unwellness before the spots, so I don't believe for one minute that the woman who posts her kid in hospital when she has a temperature didn't mention it AT ALL. I reckon it's just a spot from some medical (cleaning) grade chemicals she's lashed on her, probably had some eczema and her mother has made it worse.
