The PubMed database was searched on 4 January 2021 for research investigating lengthy COVID amongst youngsters, leading to one paper together with a case description of 5 youngsters in Sweden. Further, Google Scholar was searched, and one preprint examine from Italy, together with 75 lengthy COVID youngsters with out controls, was discovered.

Furthermore, the ClinicalTrials.gov web site talked about ongoing research which reported a excessive prevalence of long-lasting signs. Still, the research had been small, didn’t embody the youngest age teams, and lacked management teams and laboratory-confirmed SARS-CoV-2 experiences. Few research reported signs to be additionally extremely prevalent amongst controls. Moreover, most research used a cutoff of 4 weeks for lengthy COVID, whereas the World Health Organization (WHO), in October 2021, outlined lengthy COVID to be lasting eight weeks.

Results

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. Long 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 kids aged 12 to 14 years.
