Cold and fever symptoms: what to know

A cold commonly causes a blocked or runny nose, sneezing, sore throat, cough, and tiredness. Fever can add warmth, chills, sweating, headache, muscle aches, and reduced appetite. COVID-19, acute bronchitis, bronchiolitis, and croup may begin with overlapping respiratory symptoms, especially in children. Symptoms do not identify a specific infection by themselves. Age, existing illness, exposure history, breathing, hydration, and the direction of change are more useful than one isolated symptom.

Rest, drink regularly, and choose light meals as tolerated. Saline nasal drops or spray may ease congestion; warm fluids can soothe a throat. Use a thermometer and write down symptoms and medicines. Follow package directions and professional advice for fever relief, especially for children, pregnancy, liver or kidney disease, or use of combination cold products. Avoid smoke and share less personal space while fever or active respiratory symptoms continue.

Seek urgent help for breathing difficulty, blue lips, chest pain, confusion, severe dehydration, a seizure, or inability to wake normally. Arrange prompt review for a child who is working hard to breathe, a fever in a very young infant, worsening symptoms after initial improvement, or symptoms in someone with significant heart, lung, or immune problems. A persistent or severe headache, stiff neck, or unusual rash also needs urgent assessment.

Ask which symptoms need monitoring, whether an infection test is useful, which medicines are safe, and when normal activities can resume. Mention breathing rate or effort, fluid intake, temperature readings, exposure to illness, and any chronic conditions.
