scarlet fever
A skin condition that is due to a
streptococcal sore throat or any other streptococcal
infection. The group A streptococcal bacteria pro-

appears on the neck and chest, then spreads over

desquamation (peeling) may occur around the fin-
gertips, toes, and groin area. Scarlet fever is usually
not a serious illness when treated promptly with
antibiotics such as penicillin. However, untreated
