What Causes Allergic Skin Rash On Arms And Ears After Snorkeling?

My 11 year old son went on a 3 night school field trip to Catalina Island in California. They did a lot of snorkeling and hiking. One week after returning several kids are breaking out with a red bumpy rash on the top of their hands, arms, and ears. The rash is not itchy. The school has no idea what it is.

Hi...by what you quote I feel this could be a hand foot mouth disease epidemic going on in the school. This is one viral illness among all other exanthemas which can cause fever followed by rash over palms and soles. It is a self-limiting disorder and itching can be really worrisome. I suggest you use any over the counter antihistamine if you have one with you now. You can use Hydroxyzine at 1-2mg/kg/dose (Maximum 10mg) every 6th to 8th hourly for 7 days.
This can even cause some peeling of skin in the next 4-6 weeks and do not worry about it.
