Long COVID Risk Likely Exaggerated Due to Flawed Research, Says New Study

The actual risk of long COVID has been distorted, according to a new study, due to methodological flaws including overly broad definitions and a lack of appropriate, or any, comparison groups in epidemiology studies looking at the incidence, prevalence, and control of the condition, also known as post-acute sequelae of COVID-19 (PASC). The study was published in BMJ Evidence Based Medicine.

The authors of the study are affiliated with the Epidemiology and Biostatistics department at the University of California San Francisco, the University of Southern Denmark and St George's University of London, UK.
