What should you know about strawberry tongue and fever?

The tongue may look unusually red, swollen, or dotted because the taste buds stand out against an inflamed surface. Fever with this change may occur alongside a sore throat, swollen glands, rash, cough, runny nose, vomiting, or eye symptoms. Viral illnesses are possible, while some bacterial illnesses can also cause a red tongue and fever. The appearance alone cannot identify the cause. Babies, young children, older adults, and people with weakened immunity may become unwell more quickly.

Offer frequent fluids and rest, and choose cool, soft foods if the tongue or throat is sore. Measure temperature with a reliable thermometer and note the timing of fever, rash, medicines, and changes in drinking or urination. Avoid giving leftover antibiotics. A clinician may need to examine the throat, skin, eyes, and tongue and decide whether testing is appropriate, particularly when fever persists or the person looks unwell.

Seek emergency help for breathing difficulty, inability to swallow saliva, rapidly increasing tongue or throat swelling, blue or grey lips, severe drowsiness, confusion, a seizure, or signs of shock. Arrange same-day medical advice for a child who is unusually sleepy, refusing fluids, passing very little urine, or developing a widespread rash. Prompt assessment is also needed for persistent fever, severe pain, or rapid deterioration.

Which accompanying signs help distinguish a viral illness from another cause? Does the throat or skin need examination or testing? How can I keep fluids going, and which fever medicine is suitable?
