He further added that some areas showed over one half to two third of sampled population to have positive samples for COVID antibodies. Nine hundred fifty-nine (959) samples were positive for IgG against SARS-CoV-2 living a sero-prevalence of 40.6%., he said, adding that out of the 2,361 participants, 1,335 were male and 1,026 were female and the sero-prevalence was significantly higher among females (459/1026=44.7%) as compared to males (500/1335=37.5%).
Moreover the sero-prevalence also increased significantly with age and those with a history of ILI-symptoms in the previous three months, and those with a history of contact with a known COVID-19 case had higher sero-prevalence as compared to their counterparts with no such history, he said, while adding that out of a total of 115 participants who reported having a positive COVID-19 test (RAT/RT-PCR) ever, 95 (82.6%) were sero-positive and among the 432 participants who reported a negative COVID-19 test (RAT/RT-PCR), 159 (36.8%) were sero-positive.
