How common is runny nose in COVID-19?

COVID-19 can irritate the upper airways and cause watery nasal drainage. Because a runny nose also occurs with colds, influenza, and allergies, this symptom cannot identify COVID-19 by itself. Consider the full pattern, recent exposure, and current public-health guidance. Testing, when available and appropriate, can help clarify the cause. People at higher risk from respiratory infection should seek timely clinical advice if new symptoms begin, since early assessment may affect treatment choices.

Follow current local advice about testing, staying away from others, and returning to normal activities. Rest, drink fluids, and use simple saline measures for nasal irritation. If you test positive or suspect infection, reduce close contact with vulnerable people and improve ventilation where possible. Contact a healthcare professional promptly if you have a long-term medical condition, a weakened immune system, or symptoms that are becoming more intense. Do not start prescription treatment without individual medical advice.

Get urgent medical help for difficulty breathing, persistent chest pain or pressure, new confusion, inability to stay awake, or blue, grey, or unusually pale lips or skin. Seek advice if fever or breathing symptoms worsen, you cannot maintain fluids, or you are concerned because of pregnancy, age, or a chronic condition.

Should I test now or repeat testing? How long should I limit close contact? Am I eligible for early treatment because of my health history? Which medicines can I use for nasal symptoms?
