A significant proportion of SARS-CoV-2 infections in Africa were identified as asymptomatic. With the surge Omicron variant, asymptomatic participants epidemiological surveys key to accurately estimating seroprevalence and true population. This study assessed seroprevalence, active infections, circulating variants Accra, Ghana, during wave. Secondary objectives included assessing association between sociodemographic factors, vaccination, adherence recommended prevention control measures. We conducted a cross-sectional survey Greater Accra December 2021 using standardized questionnaire. Serum naso-oropharyngeal swab samples collected from 1027 individuals aged ≥ 5 years for estimation total antibodies detection infection. The found an overall 86.8% [95% CI: 84.53–88.77]. PCR test positivity was 10%, with Delta accounting 44.1% 8.8% respectively. Vaccination (cOR = 10.5, 95% 4.97–26.9, p < 0.001) older age, particularly 60+ age group 6.05, 2.44–20.2, 0.001), associated increase odds seropositivity among participants. High indication high exposure transmission rates and/or vaccine-induced seroprevalence.
