Analysing electronic health records from more than 273,000 US patients with Covid-19, researchers found 37% had one or more long Covid symptoms recorded between 3 and 6 months after diagnosis, and this was significantly higher than the risk of post-viral symptoms following the flu. Long Covid risk was higher in people with more severe initial illness, and slightly higher in females and young adults. This study sheds fresh light on long Covid since earlier studies have largely drawn on self-reported data or small studies, and the authors say clinical services need to deliver evidence-backed treatment of long Covid.
