Scarlet Fever: Scarlet fever, also known as scarlatina, is an illness resulting from an infection with group A streptococcal bacteria, affecting a small number of individuals who have strep throat. The time between getting strep and developing scarlet fever is brief, usually around 72 hours, but it can vary from 1 to 7 days. The illness typically starts with a fever and may be accompanied by chills, vomiting, abdominal discomfort, and more.The strep bacteria produce a toxin that leads to a rash, which usually appears 1 to 2 days after symptoms begin. Initially, the rash shows up on the neck and chest, then spreads over the entire body. It starts as small red spots that gradually become raised. After a few days, the redness begins to fade, leaving behind a rough, "sandpaper-like" texture. During the red phase of the rash, bright red lines, known as Pastia's lines, may develop in the underarm and groin creases. The rash typically lasts about 3 days. As it fades, peeling may occur around the fingertips, toes, and groin area.A throat culture should confirm the presence of group A Strep, and a rapid throat swab test is available. Treatment involves using antibiotics, often penicillin, to combat the infection, and managing symptoms with pain relievers, rest, and adequate hydration. With timely treatment, scarlet fever is generally not severe, and patients usually start to feel better within 24 hours of beginning therapy. It is rare for the bacteria to spread to other body parts, but if it does, it could lead to complications such as ear infections, glomerulonephritis, or rheumatic fever.
