Introduction. Currently, sequencing has been the only tool for the identifcation of circulating severe acute respiratory syndrome
coronavirus-2 (SARS-CoV-2) variants. However, it is known to be an expensive and laborious approach involving high technical
expertise. Considering the reduced adherence to preventive measures postlockdown in Accra, this study presents an alternative
method that leverages polymerase chain reaction (PCR) to identify circulating SARS-CoV-2 variants in the Accra Metropolis
postlockdown. Methods. Tis prospective cross-sectional study was conducted between July and December 2022. Nasopharyngeal
samples were collected from 268 consenting participants. Samples were subjected to nucleic acid extraction and followed by real-
time polymerase chain reaction for the detection and quantifcation of SARS-CoV-2 RNA. SARS-CoV-2 positive samples were
subsequently subjected to variant identifcation using rapid PCR. Findings. Te prevalence of SARS-CoV-2 within the Accra
Metropolis was 30.2%. Te majority of the SARS-CoV-2 infection was diagnosed in females, participants aged 41–50years, and
symptomatic participants. Participants aged ≤10 years and females recorded the highest viral load while participants aged
41–50years recorded the highest number of infections. Te SARS-CoV-2 variants detected were Alpha (64.2%), Delta (22.2%),
and Omicron (13.6%). Predictors of SARS-CoV-2 infection identifed were chills, cough, headache, body weakness, sore throat,
and dyspnoea in order of decreasing association with SARS-CoV-2 infection. Tere was a strong association between symptom
status, gender, age, and SARS-CoV-2 infection. Conclusion. Tere was a high prevalence of SARS-CoV-2 within the Accra
Metropolis postlockdown within the sampling period. Te Alpha variant of SARS-CoV-2 is the predominant circulating variant,
and persons presenting with symptoms are most likely to be diagnosed with COVID-19. Children aged ≤10 years serve as
a reservoir for infection transmission.
