Abstract

In a Nicaraguan population-based cohort, SARS-CoV-2 seroprevalence was 34%, with higher prevalence in children compared to adults. Having a seropositive household member was associated with a two-fold probability of individual seropositivity, suggesting a role for household transmission. Co-morbidities and preventive behaviors were not associated with SARS-CoV-2 seroprevalence.

    5 We used an in-house enzyme-linked immunosorbent (ELISA) assay to measure antibodies (IgG, IgA, and IgM) to the receptor binding domain (RBD) of the SARS-CoV-2 spike protein, which we have previously shown to be highly sensitive and specific for detecting antibodies for at least six months among individuals experiencing symptomatic infection.

    About SciScore

    SciScore is an automated tool that is designed to assist expert reviewers by finding and presenting formulaic information scattered throughout a paper in a standard, easy to digest format. SciScore checks for the presence and correctness of RRIDs (research resource identifiers), and for rigor criteria such as sex and investigator blinding. For details on the theoretical underpinning of rigor criteria and the tools shown here, including references cited, please follow this link.
