Children with bumps like small rice grains accompanied by itchiness, fever and sore throat are mostly considered to be scarlet fever. It is an acute infectious disease caused by streptococcal infection, with three main clinical manifestations, fever, pharyngitis and rash. Fever is mostly persistent and high, and the level and duration of fever are consistent with the amount and length of the rash. The rash is most often seen as a milia-like rash on top of diffuse congestion throughout the body, and in the skin folds, the rash is dense in reddish lines called pachyderms or linear rashes. The rash usually lasts for 48 hours and peaks, then fades in the same order as the rashes, and begins to peel after the rash subsides. This condition must be seen in hospital and treated with a full course of antibiotics, usually penicillin or cephalosporin for 7-10 days.
