Epidemiology of COVID-19 infection in young children under five years: A systematic review and meta-analysis. meta-analysis estimates suggest that 50% of young COVID-19 cases were under one year old, 53% were male, 43% were asymptomatic, and 7% had severe disease that required intensive-care-unit admission. Although all the children in the study had a confirmed diagnosis of COVID-19, 71% were treated with antibiotics. Vaccine 05-DEC-2020.
Antibody responses 8 months after asymptomatic or mild SARS-CoV-2 infection. Antibody positivity differed significantly between the immunoassay methods, suggesting a possible explanation for previous studies’ findings of waning humoral immunity in survivors of asymptomatic or mild COVID-19.
