37% of people had at least one long-COVID symptom diagnosed in the 3-6 month period after COVID-19 infection. The most common symptoms were breathing problems, abdominal symptoms, fatigue, pain and anxiety/depression.
This new study from the University of Oxford and the National Institute for Health Research (NIHR) Oxford Health Biomedical Research Centre (BRC) investigated long-COVID in over 270,000 people recovering from COVID-19 infection, using data from the US-based TriNetX electronic health record network. The study reports on how commonly nine core long-COVID symptoms were diagnosed, and how this rate compared to people recovering from influenza.
