Fever, rash and runny nose: what to know

A runny nose means mucus is draining from the nose; it may be clear, cloudy, or thick. Fever supports an infectious explanation, while allergies more often bring sneezing, itchy eyes, and recurring clear discharge without a fever. A common cold, influenza, or COVID-19 can combine nasal symptoms with fever and a rash may occur alongside some viral illnesses. Facial pressure, worsening blockage, or pain after initial improvement can occur with sinusitis. The rash’s shape, distribution, itch, and speed of spread matter, particularly if it involves the eyes or mouth.

Rest, drink fluids, and use a clean tissue or elbow when coughing or sneezing. Saline nasal spray or drops may ease congestion; gentle blowing helps prevent pressure from forceful blowing. Keep the room comfortably cool and avoid smoke or strongly scented products. Do not start antibiotics because of mucus colour alone. Check fever medicines carefully against the label and ask a pharmacist about suitable options for children, pregnancy, allergies, or regular medicines. Consider staying home from close contact while fever or significant respiratory symptoms continue, and ventilate shared spaces.

Seek urgent help for difficulty breathing, blue or grey lips, severe drowsiness, confusion, dehydration, a stiff neck, seizure, facial swelling, or a purple or non-blanching rash. Arrange prompt assessment when fever is persistent or returning, the rash spreads quickly, there is severe headache or facial pain, or the person is an infant, pregnant, elderly, or immunocompromised. A clinician may assess the throat, lungs, skin, and hydration, then decide whether testing is useful.

Ask: Does the rash fit an infection or an allergy? Should I test for influenza or COVID-19? What symptoms would suggest sinusitis? Which nasal or fever medicines are suitable for me? How long should I avoid close contact, and when should I return if the symptoms do not settle?
