The survey was conducted from May 11 to June 4 and included 28,000 individuals whose blood samples were tested for IgG antibodies using the COGID armor ELISA kit.
Furthermore, seropositivity was highest in the age group of 18–45 years (43.3 percent), followed by those between 46–60 years (39.5 percent) and lowest among those aged over 60 (17.2 percent).

The survey report stated that a total of 64,68,388 adult infections were estimated in India by the beginning of May.
“Our survey findings indicated that overall spirality was lower in India, less than one percent of SARS-CoV-2 as of May 2020.
The survey report asserts that low prevalence in most districts is an indication that India is in the early stage of the epidemic and that the Indian population is still susceptible to SARS-CoV-2 infection.
It also emphasized the need to continue to implement context-specific prevention measures, including testing for all symptomatology, isolating positive cases and detecting high-risk contacts for slow transmission, and preventing overlapping of the health system Cast light on.
Males were associated with increased serospectivity, with a higher risk of exposure to urban slums and potentially infected individuals.
According to the survey report, seroprevalence occurred in four parts of the districts between 0.62 and 1.03 percent.

The stratification of districts as zero cases (15 districts), low (22 districts), medium (16) and high (17) was done on 25 April based on the perceived number of Kovid-19 cases.
Based on an overall adjusted seroprevalence of 0.73 percent and the reported number of Kovid-19 cases, it was estimated that there were 82–130 infections in India for every confirmed case of RT-PCR of Kovid-19.
As a part of the survey, a total of 30,283 houses were visited from 700 groups in 70 districts in four sections. About one-quarter (25.9 percent) of the groups surveyed were from urban areas. The report stated that a total of 28,000 people attended.
About half (48.5 percent) of the participants were aged between 18 and 45 and 51.5 percent (14,390) were women. In all, 18.7 percent of participants had a high risk of exposure to potentially infected individuals.
The survey mentions that Kovid-19 cases can be detected in zero stratum districts due to poor testing as well as poor access to testing laboratories.
In four of the 15 districts in this stratum, Kovid-19 testing laboratories were not available at the district headquarters and samples were transported to state headquarters hospitals for diagnosis.
The survey report stated that the current monitoring of communalism in the situation of districts with less than zero incidence of Kovid-19 cases underscores the need to strengthen surveillance and increase the trial of suspected cases.
