27% Mumbai health workers have Covid-19 antibodies

The second sero-survey of SARS- CoV2 in Mumbai has found that only 27 per cent of health workers have developed antibodies despite being in constant contact with Covid-19 patients, the city civic body said on Friday.

According to the Brihanmumbai Municipal Corporation (BMC), in the first and as well as in the second round of sero-survey, approximately 27 per cent health workers, who are more exposed to the virus than ordinary citizens, were found to have developed antibodies against the infection.
