Furthermore, most research used a cutoff of 4 weeks for lengthy COVID, whereas the World Well being Group (WHO), in October 2021, outlined lengthy COVID to be lasting eight weeks.

Outcomes

A complete of 10997 responses (28.8%) and 33016 responses (22.4%) had been obtained for instances and controls, respectively, between 20 July 2021 and 15 September 2021. The imply age of the instances and controls was ten years and 10.6 years, respectively. Lengthy COVID was current in 31% (n = 427) youngsters aged 0 to three years, 26.5% (n=1505) youngsters aged 4 to 11 years, and 32·5% (n = 1077) of youngsters aged 12 to 14 years.
