Post-Acute COVID-19 Syndrome (PACS) in Adults, Published: April 2022. “Introduction – Public Health Ontario (PHO) is actively monitoring, reviewing and assessing relevant information related to Coronavirus Disease 2019 (COVID-19), caused by severe acute respiratory coronavirus 2 (SARS-CoV-2). This rapid review concentrates on results from systematic reviews and meta-analyses, updating the evidence on the prevalence of PACS, PACS symptoms by organ system and risk factors for developing PACS. The update includes more meta-analyses and primary research with larger sample sizes and includes a new section reporting on the impacts of PACS on daily living. This rapid review replaces Persistent Symptoms and Post-Acute COVID-19 in Adults –What We Know So Far (April 9, 2021).

Key Messages

• The definition of and diagnostic criteria for post-acute COVID-19 syndrome (PACS) are not yet well established. This rapid review considered PACS as persistent or new sequelae present 3or more weeks after severe, mildly symptomatic or asymptomatic SARS-CoV-2 infection.
• Pooled mean prevalence results for any experience of PACS, extracted from nine systematic reviews, ranged from 51%–80%.

“It is estimated by @PeterHotez [Director of the Port Stephens GP Super Clinic, OzSAGE Member] that there are roughly 32 million people with long Covid currently in the USA.”
