Students at a charter school where I work came to school with red itches on their body. The nurse put some cream on them and I was surprised they allowed them in school that way. I wondered if they had chicken pox or scabies. It was small red marks on their body, arms, and I remember the cream they had on was pink,... think it would be good to see a doctor as well as check with the nurse about the rash that is going around the school. If you had chicken pox as a child you shouldn't be getting it a 2nd time. However, if it's scabies they wouldn't be using calamine lotion on it.
Scabies is spread to others through close skin-to-skin contact. It is easily treated with an insecticide lotion applied to the skin. Two applications of treatment are needed, one week apart. Scabies is caused by a mite (like a tiny insect) called Sarcoptes scabiei. The mite is a parasite, meaning it lives off the host (a human) with no benefit to the host. Scabies mites are tiny. They have a cream-coloured body, bristles and spines on their back, and four pairs of legs. The female mite is bigger (about 0.4 mm x 0.3 mm) compared with the male (0.2 mm x 0.15 mm).
