Where does rashes for chicken pox start?

Face or scalp...: The pox lesions of chicken pox may arise anywhere on the body; however, typically most parents are first alerted to this viral infection when spotting the lesions on their child's face or scalp. Since this area is unclothed, it allows a greater likelihood for discovery; these also have the most generous blood supply, thereby increasing the viral load in these areas. Clothed areas may have pox, too.
