Abstract
CANTO-OSORIO, Francisco et al. Seroprevalence of SARS-CoV-2 in Mexican children and adolescents in primary and secondary education age. Salud pública Méx [online]. 2021, vol.63, n.6, pp.803-806. Epub Feb 27, 2023. ISSN 0036-3634. https://doi.org/10.21149/12847.
Objective:
To estimate the seroprevalence of SARS-CoV-2 in school aged children in Mexico.
Materials and methods:
We categorized children and adolescents who participated in the 2020 National Health and Nutrition Survey on Covid-19 according to school age and educational level. In seropositive participants, we identified the proportion of asymptomatic infections. We estimated prevalence ratios using a log-binomial regression model.
Results:
Seroprevalence of SARS-CoV-2 for primary and secondary education were 18.7% (95%IC: 14.9, 22.5) and 26.7% (95%IC: 22.1, 31.3), respectively. Asymptomatic infection was more frequent among primary school children (88.5% [95%IC: 80.5, 93.5]).
Conclusions:
In primary schoolchildren seroprevalence for SARS-CoV-2 was low and infections were usually asymptomatic.
