Prevalence Of Immunoglobulin G (Igg) Against Severe Acute Respiratory Syndrome Coronavirus 2 (Sars-Cov-2) And Evaluation Of A Rapid Medsan Igg Test In Children Seeking Medical Care

In 208 children seeking medical care, the seropositivity rate of anti-SARS-CoV-2 IgG antibodies was 8.7%, suggesting an infection rate similar to that observed in adults but >100-fold the incidence of RT-PCR-confirmed pediatric cases. Compared with the gold-standard combined ELISA + immunofluorescence, the MEDsan IgG rapid diagnostic test performed accurately.
