How long after having COVID can you get it again?

A new infection is possible when your immune protection decreases or a different virus variant is less well recognised by your immune system. A positive test or new symptoms after recovery may reflect reinfection, but lingering symptoms alone do not prove that the virus has returned. Loss of smell, loss of taste, fatigue, or joint pain can continue during recovery and may also occur with Long COVID.

The timing depends on your previous illness, immune health, exposure, vaccination history, and the variants circulating around you. Someone who has had COVID-19 can still pass it to others during a new infectious episode.

If symptoms return, stay away from people at higher risk while you arrange testing and follow current local public-health advice. Rest, drink fluids, and monitor how you feel. A clinician can help distinguish a new infection from ongoing recovery, especially if symptoms such as difficulty concentrating or fatigue are interfering with daily activities.

Keep vaccination advice current for your age and health needs, and improve ventilation when sharing indoor spaces. Do not rely on a previous infection as complete protection.

Seek urgent medical help for severe trouble breathing, persistent chest pain or pressure, new confusion, inability to stay awake, or blue, grey, or very pale lips or skin. Contact a clinician promptly if symptoms are worsening, you are pregnant, or you have a condition or treatment that weakens immunity.

Ask whether your symptoms fit reinfection or ongoing recovery, which test is appropriate, how long to reduce close contact, and whether you need early treatment because of your medical history.
