  • Seroprevalence survey, for antibodies to SARS-CoV-2, of healthcare workers (HCW) working in three Government run hospitals in Mumbai was carried out in June 2020 Among the 801 HCWs tested, seroprevalence was 11 1% Males (13 5% vs 8 9% in females) and ancillary workers (18 5% vs 6 9% in doctors and nurses) were more likely to be seropositive Sixty-two (7 74%) had been previously diagnosed with RT PCR test for SARS-CoV-2 Of these, 44 (71%) were seronegative Upto 28 days after a positive PCR test, 90% of subjects were found to be seropositive This reduced to less than half (38 5%) between 29 and 42 days None of 28 infected HCWs who had the RT-PCR more than 50 days ago tested positive for antibodies It seems likely that cellular immunity plays a larger role in defence against the illness
  • Seroprevalence survey, for antibodies to SARS-CoV-2, of healthcare workers (HCW) working in three Government run hospitals in Mumbai was carried out in June 2020. Among the 801 HCWs tested, seroprevalence was 11.1%. Males (13.5% vs. 8.9% in females) and ancillary workers (18.5% vs 6.9% in doctors and nurses) were more likely to be seropositive. Sixty-two (7.74%) had been previously diagnosed with RT PCR test for SARS-CoV-2. Of these, 44 (71%) were seronegative. Upto 28 days after a positive PCR test, 90% of subjects were found to be seropositive. This reduced to less than half (38.5%) between 29 and 42 days. None of 28 infected HCWs who had the RT-PCR more than 50 days ago tested positive for antibodies. It seems likely that cellular immunity plays a larger role in defence against the illness.
