What is the most common cold virus?

Rhinovirus spreads through respiratory droplets, close contact, and contaminated hands or surfaces. It commonly causes a blocked or runny nose, sneezing, sore throat, and cough. Several different viruses can produce the same pattern, so symptoms usually cannot identify the exact virus. A cold may irritate nearby areas and be followed by sinusitis, an earache, or acute bronchitis. Croup is a different airway illness that is more concerning when a child has a barking cough or noisy breathing.

Rest, drink regularly, and use warm fluids or saline to soothe the nose and throat. Wash hands, cover coughs and sneezes, and avoid close contact while feeling unwell. A pharmacist can help you choose symptom relief that fits your age, pregnancy status, and other medicines. Antibiotics do not treat viruses. Keep children away from smoke and seek advice before giving them any over-the-counter medicine.

Get urgent help for difficulty breathing, blue or grey lips, severe drowsiness, dehydration, or a child with noisy breathing at rest. Arrange medical advice if fever is persistent or returns after improvement, symptoms are worsening, chest pain develops, or a cough lasts longer than expected. People with significant lung disease or reduced immunity may need earlier review.

Ask whether the symptoms fit a cold, which relief options are safe with your medicines, and which changes would suggest a chest or ear complication. Mention breathing problems, fever, and how long symptoms have been present.
