Estimated prevalence of post-COVID-19 symptoms over time, stratified by epidemic periods, age group, and severity (IMAGE)
Caption
Survival analysis was conducted using the Turnbull method to estimate the prevalence of persistent post-COVID-19 symptoms. The x-axis indicates months since recovery from acute infection. Curves represent infection period groups: blue, Wild (Apr 2020–Feb 2021); light blue, Alpha (Mar 2021–Jun 2021); green, Delta (Jul 2021–Nov 2021); red, Omicron 2022 (Dec 2021–Jul 2022); and orange, Omicron 2024 (Jan 2024–Jun 2024). A) Adults; B) Children. Left panels: any level of symptom severity; right panels: symptoms interfering with daily life.
