COVID-19 symptoms: when to monitor, test and seek urgent help
COVID-19 symptoms overlap with many respiratory infections. This guide explains warning signs, when early clinical contact matters, and how to reduce exposure to others while unwell.
Symptoms vary and can overlap
COVID-19 can cause fever, cough, tiredness, sore throat, headache, muscle aches, changes in taste or smell, nasal symptoms, nausea, vomiting or diarrhoea. These symptoms can also occur with influenza and other respiratory infections, so symptoms alone cannot reliably identify the cause.
Start with the situation around you
Consider when symptoms began, recent close contact, whether you live or work with someone at higher risk, and whether your condition is improving or worsening. While unwell, reduce close contact with others when practical, improve ventilation, and use a well-fitting mask if you need to be around people.
When testing or early clinical advice matters
People at higher risk of severe illness should contact a healthcare professional promptly when they develop compatible symptoms or test positive, even when symptoms are mild. Some treatments have a limited time window and the right option depends on personal health, medicines and local availability. Do not self-start prescription treatment.
Urgent warning signs
Seek urgent medical help for trouble breathing, persistent chest pain or pressure, new confusion, inability to wake or stay awake, or pale, grey or blue lips, nail beds or skin depending on skin tone. This list is not complete: seek care for any severe or rapidly worsening symptom.
Recovery and follow-up
Most people recover without hospital care, but symptoms and recovery time differ. Rest, fluids as appropriate, and following local health advice may help. Contact a clinician if symptoms do not improve, return after getting better, or interfere with daily life for a prolonged period.
