Roughly eight of 10 people in Haryana, or 76.3% of the states population, have antibodies against SARS CoV2 the virus that causes Covid-19 the third sero survey, which also had the largest sample size, has found. Gurgaon, the district that has reported the most cases so far in Haryana, has slightly better seropositivity with 78.3% of the population having antibodies.

According to data released on Monday, seropositivity is 78% in urban areas and 75% in rural areas of Haryana. Kurukshetra, with 85%, has the highest seropositivity and Faridabad (64.2%) the lowest in the state. In Faridabad, however, the survey will be carried out again. As 14% of the samples were found to be inconclusive, we are planning to carry out another sero survey. All the samples were processed at a lab in Panchkula to ensure that the samples are uniformly treated, said health minister Anil Vij.

A sero survey involves testing a group of individuals to monitor trends in the prevalence of an infectious disease. Due to the high proportion of asymptomatic or mild infections, data available only for lab-confirmed cases does not capture the real spread of Covid in the population. Hence, serological detection of specific antibodies against SARS CoV-2 can better estimate the true number of infections.
