ICMR conducts sero survey in 15-district across India, says less than 1% population have Covid-19 infection

India's first sero-survey on COVID-19 spread has found that lockdown and containment measures were successful in preventing a rapid rise in infections, but a large proportion of the population still remains susceptible, said ICMR. The sero-survey has found that 0.73 per cent of the population in the districts surveyed had evidence of past exposure to SARS-CoV-2 , said Prof Balram Bhargava, DG, ICMR, Delhi.
