What are the first signs of COVID-19?

COVID-19 can start with a combination of general viral symptoms rather than one defining sign. You may develop [Fever](/symptoms/fever/), [Headache](/symptoms/headache/), [Muscle Aches](/symptoms/muscle-aches/), tiredness, [Runny Nose](/symptoms/runny-nose/), or reduced appetite. Some people notice [Loss of Smell](/symptoms/loss-of-smell/) or [Loss of Taste](/symptoms/loss-of-taste/), although these changes are not present in every illness. Symptoms can overlap with other respiratory infections, so symptoms alone cannot confirm the cause.

Stay home while you feel unwell and reduce close contact with other people, especially those at higher risk of severe illness. Rest, drink fluids, and follow local advice about testing and returning to normal activities. Keep a record of when symptoms began and any medical conditions or medicines you use. Contact a clinician early if you are pregnant, immunocompromised, or have a condition that may increase the risk of severe COVID-19; treatment decisions can depend on timing.

Seek urgent medical help for trouble breathing, persistent chest pain or pressure, new confusion, difficulty staying awake, or pale, grey, or blue lips or skin. If fever or weakness is worsening, you cannot keep fluids down, or you are concerned because of an underlying condition, contact a clinician promptly. More condition information is available under [COVID-19](/conditions/covid-19/).

Ask whether testing is advised, how long to limit contact, which treatments may be suitable for your health history, and which warning signs should trigger urgent care.
