According to the survey, 64,68,388 infections were estimated in India in early May.

new Delhi: The much-awaited findings of the first national Cesarovay conducted by ICMR published in the Indian Journal of Medical Research indicated that 0.73 percent of adults in India were exposed to SARS-CoV-2, with 6.4 million infections overall. early May.

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 based on the reported number of COVID-19 cases as of 25 April.

Based on the total adjusted adjustment of 0.73 percent and the reported number of COVID-19 cases, it was estimated that there were 82–130 infections in India for each RT-PCR confirmed case of COVID-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 states that COVID-19 cases can also be detected due to poor testing in Zero Stratum districts as well as poor access to testing laboratories.

In four of the 15 districts in this stratum, COVID-19 testing laboratories were not available at district headquarters and samples were transported to state headquarters hospitals for diagnosis.

The survey report noted that the current finding of communalism in sections of districts with less than zero incidence of COVID-19 cases underscores the need to strengthen surveillance and increase the testing of suspected cases.
