How long should you wear a mask after COVID?

Masking reduces the chance of passing respiratory droplets and aerosols to people nearby, but no single sign proves that transmission has ended. Risk is higher in crowded, poorly ventilated indoor spaces and around people who may become seriously ill. A lingering cough can remain after infection, while fatigue or loss of smell can continue without meaning that you are infectious. Follow workplace, healthcare and local public-health instructions when they are stricter.

Choose a comfortable mask that seals around the nose, cheeks and chin, and replace it when damp, dirty or damaged. Improve ventilation, avoid close indoor contact while unwell and cover coughs. If you must meet someone vulnerable, mask and shorten the visit. Wash hands before touching the mask, handle it by the straps and avoid repeatedly adjusting the front. Return to activities gradually if fatigue is still limiting you.

Arrange medical advice if fever returns, symptoms worsen after improvement, or breathing becomes harder. Seek urgent help for severe breathlessness, chest pressure, fainting, new confusion, blue or grey lips or inability to stay awake. A clinician can help distinguish ongoing COVID-19 symptoms from complications or Long COVID.

Ask when you can safely stop masking in your setting, whether you need extra precautions around a high-risk household member, and what to do if symptoms fluctuate. Mention any persistent cough, fatigue or low mood.
