Looks like chickenpox or measles, itchy rash, its small little bump. no other symptoms except the rash he has it everywhere on hos body except in his mouth ears and face - although it looks like there is some rash by his hairline?

See your DR.: This sounds like a problem that needs to be seen by a Dr either in person or on telemedicine. History including age of the patient and previous medical problems as well as other findings including throat, tongue and fingernails are important to determine the cause. Make sure to keep this person isolated until a diagnosis is made so that it cannot spread to others.
