Some teenagers have suffered from long Covid for more than two years, researchers have found. However, the majority who had long Covid three months after first testing positive will recover, according to the largest study of its kind.
Experts said that more work is needed to understand why some children still have ongoing health problems two years after infection.
Researchers from across the UK, led by experts from University College London (UCL), examined data on thousands of older children and teenagers.
Young people aged 11 to 17 were asked about their health three, six, 12 and 24 months after taking a PCR test for the Covid virus between September 2020 and March 2021.
