What should you know about coronavirus symptoms?

Possible symptoms include cough, fever, sore throat, headache, fatigue, muscle aches, a blocked or runny nose, and a general feeling of being unwell. Some people have only a few symptoms, while others become more ill. Symptoms can begin after exposure and may change over the following days. The presence of a symptom does not prove COVID-19, because flu, other infections and non-infectious conditions can feel similar.

A [COVID-19](/conditions/covid-19/) diagnosis uses the overall picture, including your history, examination and testing when suitable. Note when each symptom started, whether it is improving, and whether breathing or daily activity is becoming harder.

Follow local advice about testing and limiting contact while you are unwell. Rest, drink fluids regularly and choose simple food if your appetite is low. Improve ventilation and avoid close contact with people who could become seriously ill. Take medicines according to the label and ask a pharmacist or clinician if you are pregnant, have another condition, or use regular medicines. Check your symptoms at intervals rather than relying on one brief improvement.

Call emergency services for severe difficulty breathing, chest pain or pressure, sudden confusion, inability to wake or stay awake, or blue or grey lips or skin. Seek prompt medical advice for worsening breathlessness, persistent fever, inability to drink, very little urine, or severe weakness. A cough with breathlessness or chest pain needs assessment for complications including [Pneumonia](/conditions/pneumonia/). Ongoing symptoms after infection, such as fatigue, may warrant review for [Long COVID](/conditions/long-covid/).

Ask whether you need testing or treatment, how to protect household members, and which changes require urgent review. Give the clinician your symptom timeline, temperature readings if taken, medical conditions and current medicines.
