Scarlet fever face rash: what to know

Scarlet fever commonly produces a fine, rough rash that can feel like sandpaper. It often begins on the chest or stomach and may spread, while the face can look flushed. The area around the mouth may remain relatively pale. Rash appearance varies with skin tone, and a rash can be harder to see than to feel. A face rash alone cannot establish the diagnosis; fever, sore throat, swollen neck glands and examination findings help a clinician judge whether group A strep infection is involved. Other rashes can resemble it.

Contact a clinician if a new rough rash appears with fever or sore throat, especially if the person is a child. Keep the skin cool, use gentle fragrance-free washing, and discourage scratching. Do not share towels, cups or cutlery while an infectious throat illness is possible. If the diagnosis is confirmed, take prescribed antibiotic treatment as directed. Keep the person home according to the clinician’s advice and wash hands regularly. Read more about Fever, Sore Throat and Antibiotic Treatment.

Seek same-day medical advice for a rapidly spreading rash, high fever, worsening throat pain, difficulty drinking, or a person who is becoming weak or unusually sleepy. Get urgent help for breathing difficulty, swelling of the lips or tongue, skin that blisters or peels extensively, purple spots that do not fade with pressure, confusion, or signs of dehydration such as very little urine. A rash with eye pain or facial swelling also needs prompt assessment.

Ask whether the rash pattern fits scarlet fever, whether a throat test is needed, which skin-care products are suitable, when the person can return to school or work, and what to do if the rash changes after treatment. Tell the clinician when the rash began and whether fever or throat symptoms came first.
