Worldwide, 49% of COVID-19 survivors reported persistent symptoms 4 months after diagnosis, estimates a meta-analysis of 31 studies published late last week in The Journal of Infectious Diseases.
Long COVID prevalence among hospitalized patients was 54%, while it was 34% for outpatients.
Estimated global prevalence of long COVID was 43%, although estimates ranged from 9% to 81%, which the study authors said may be attributable to differences in sex, region, study population, and follow-up.
