Reviews on Long COVID:A scope of the literature. Update October 2024

• For this update, we identified 38 published reviews and 35 review protocols for Long COVID. • The number of reviews (n=38) is more than July 2024 (n=33) and April 2024 (n=36), but fewer than January 2024 (n=42) and October 2023 (n=46). • As in many of the previous reports, the largest category of reviews focused on symptoms or effects (14/38) and the second largest was on treatment or rehabilitation (11/38). • We identified eight reviews on risk factors with or without prevalence, three on pathobiology or mechanisms, one on prevention, and one on diagnosis or monitoring tools. • The number of protocols (n=35) is fewer than in every previous report. • As in previous reports, the largest two categories of protocols focused on the prevalence of symptoms or effects (13/35), and treatment or rehabilitation (10/35). • We identified six protocols focused on risk factors with or without prevalence; five on pathobiology or mechanisms; and one on diagnosis or monitoring tools.
