How long does COVID stay in your body?

The body's immune system responds to the infection and gradually removes the virus. A lingering cough, tiredness, reduced concentration, joint pain, or changes in taste and smell does not by itself prove that active virus remains. Recovery is not identical for everyone, and symptoms can fluctuate with activity, sleep and other illness. Persistent or returning symptoms may need assessment for Long COVID or another explanation rather than being assumed to represent ongoing infection.

Pace daily activities and increase effort gradually instead of pushing through a marked symptom flare. Sleep regularly, eat what you can tolerate, drink enough to keep urine pale, and keep a brief record of symptoms and triggers. Reduce close contact when acutely unwell and follow current public-health advice. If fatigue, low mood, concentration problems, or changes in smell and taste interfere with work or daily life, arrange a clinical review.

Get urgent help for severe breathing difficulty, chest pain, new confusion, inability to stay awake, or blue or grey lips. Seek prompt advice for worsening symptoms, dehydration, a fever that returns, or a new symptom after initial improvement. Medical review is also appropriate when symptoms persist and prevent normal activities, because support and targeted checks may help.

Ask whether your symptoms fit expected recovery, whether testing would add useful information, and how to pace activity safely. Share when the infection began, which symptoms remain, what makes them worse, and how they affect sleep, work and exercise.
