(Emma Reynolds/ CNN) — Older people, women and those with a wide range of symptoms in the first week of their illness appear to be most likely to develop “long Covid,” according to a preprint paper posted online by researchers at King’s College London on Wednesday.
The paper defines “long Covid” as having symptoms persist for more than four weeks, while a short duration of Covid was defined as less than 10 days, without a subsequent relapse.
About 1 in 20 people with Covid-19, or 4.5%, are likely to experience symptoms for eight weeks or more, the preprint analysis of data from the Covid Symptom Study app showed. The analysis has not been published in a peer-reviewed journal.
The data was collected from 4,182 users of the app in the UK who reported testing positive for coronavirus and regularly logged their health information in the app. (…)
