Let is have a small over view about  Scarlet fever 🤒 here.  he rash of scarlet fever is caused by infection with a strain of GAS
that contains a bacteriophage encoding for production of an erythrogenic (redness producing) toxin, usually erythrogenic (also called pyrogenic) exotoxin A (designated SPE A). Scarlet fever is simply GAS  pharyngitis with a rash and should be explained as such to patients and their families. Although patients with the streptococcal toxic shock syndrome are also infected with GAS that produces SPE A, most GAS  pharyngeal infections are not associated with development of severe  invasive or systemic disease. The rash of scarlet fever has a texture like sandpaper and blanches  with pressure. It usually begins on the face, but after 24 hours, it
becomes generalized.

Accentuation of erythema occurs in flexor skin creases, especially in the antecubital fossae (Pastia lines). The erythema begins to fade within a few days. Desquamation begins within a week of onset on the face and progresses downward, often  resembling that seen after mild sunburn.

On occasion, sheet-like desquamation occurs around the free margins of the fingernails; this is  usually coarser than the desquamation seen with Kawasaki disease. The differential diagnosis of scarlet fever includes Kawasaki disease, measles, and staphylococcal toxic shock syndrome
