Untreated scarlet fever: risks and next steps

Scarlet fever is a bacterial infection associated with Strep Throat. It may cause a rough rash, sore throat, fever, red tongue, or swollen glands. Without assessment and suitable treatment, symptoms can continue and the infection may be passed through close contact.

Complications are not the usual outcome, but they can involve areas beyond the throat. This is why improvement in the rash or throat does not replace a clinical review. A clinician can check hydration, examine the throat and skin, and decide whether testing or antibiotic treatment is needed.

Contact a healthcare professional promptly, especially if the rash and throat symptoms are continuing or worsening. Keep a note of the first symptoms, temperature readings, fluid intake, and any medicines used. Rest and drink regularly if swallowing is comfortable.

Reduce spread by washing hands, covering coughs and sneezes, cleaning frequently touched surfaces, and not sharing cups, towels, or utensils. If antibiotics are prescribed, take them according to the prescriber’s directions and do not use leftover medicine.

Seek urgent medical help for difficulty breathing, inability to swallow fluids, severe dehydration, confusion, unusual sleepiness, facial swelling, or a rapidly worsening rash. Prompt review is also needed for severe throat pain, neck swelling, persistent vomiting, or new joint, chest, or urine symptoms after the illness.

Ask whether the symptoms fit scarlet fever, whether a throat test is appropriate, what treatment is recommended, when contagion is reduced, and which later symptoms should trigger review.
