What should you know about spring fever?

Fever is a body response that can occur with respiratory infections, skin infections, or illnesses spread through close contact. The accompanying pattern matters: cough and breathing symptoms may point toward a respiratory illness, while a rash, painful skin, vomiting, or marked weakness needs separate attention. A fever does not identify one diagnosis by itself, and the direction of symptoms over time is useful to a clinician.

Measure temperature with a reliable device, note when it rises, and record other symptoms, recent travel, sick contacts, new medicines, or animal exposure. Avoid assuming that warm weather itself explains a measured fever.

Rest, drink fluids regularly, wear light clothing, and keep the room comfortably cool. Follow the label or a clinician's advice before using fever medicine, especially for children, pregnancy, liver disease, kidney disease, or medicine interactions. Stay home from close contact while unwell and wash hands. Arrange a medical review when fever persists, returns, or is accompanied by worsening cough, rash, pain, or reduced drinking.

Seek emergency help for difficulty breathing, blue or grey lips, a seizure, severe confusion, a stiff neck, collapse, or a rapidly spreading painful rash. Get prompt advice for a very young infant with a fever, an older adult who becomes unusually drowsy, or anyone unable to keep fluids down.

Ask what infection or other cause fits the full symptom pattern, how often to monitor temperature, whether testing is needed, and which fever medicines are safe with your health conditions.
