John is 5 years old. One day he comes to the breakfast table with a bright red face, almost as if he had been slapped. When you look more closely you can see thousands of tiny red bumps on the skin. He has a milder rash on his arms and legs and just a few red bumps on his trunk. He isn’t acting sick and doesn’t have a fever. He had chicken pox when he was 3 and his immunization schedule is up to date. He sticks his tongue out at you while you’re examining his skin and that reminds you to check his throat, which looks normal, no redness. He says his throat hasn’t felt sore. Your mom mentions that he has had a runny nose for the last few days, but he hasn’t felt ill.
