In a Nicaraguan population-based cohort, SARS-CoV-2 seroprevalence reached 28% in the first six months of the country’s epidemic and reached 35% six months later. Immune waning was uncommon. Individuals with a seropositive household member were over three times as likely to be seropositive themselves, suggesting the importance of household transmission.
