Key Points

  • The aim is to evaluate the prevalence of SARS-CoV-2 antibodies in COVID-19-unvaccinated children and assess associated factors.
  • Conducted a cross-sectional study on unvaccinated children
  • Analyzed household size and member history of SARS-CoV-2 infection
  • Assessed activities and masking practices among participants
  • No significant link between antibody positivity and household size or member history of illness
  • Vaccination of household members associated with lower antibody positivity rates
