For some, Covid can cause symptoms that last weeks or months after the infection has gone. This is sometimes called post-COVID-19 syndrome or "long Covid".
How long it takes to recover from the virus is different for everybody, as many feel better in a few days or weeks, with most making a full recovery within 12 weeks, and for some, symptoms can last longer.
The chances of having long-term symptoms do not seem to be linked to how ill you are when you first get Covid, and people who had mild symptoms can still have long-term problems.
