The prevalence and long-term health effects of Long Covid among hospitalised and non-hospitalised populations: A systematic review and meta-analysis (1 December 2022)

Summary

This study in eClinicalMedicine aimed to bring together the global evidence on the prevalence of persistent symptoms in people who had experienced Covid-19 infection. The authors found, across the 194 studies included in the systematic review, that 45% of Covid-19 survivors, regardless of hospitalisation status, were experiencing a range of unresolved symptoms at around four months after infection. The authors state that current understanding is limited by heterogeneous study design, follow-up durations and measurement methods, and highlight that definition of subtypes of Long Covid is unclear, which hampers effective treatment and management strategies.
