The second national seroserve of the ICMR states that about seven percent of India’s population, whose age is 10 years or more, had been infected with SARS-CoV-2 by August. Their number will be around 74.3 million. In this, the maximum number of urban slums are followed by urban non-slum and rural areas. According to a report by the Lancet Global Health Pre-Print, less than 10 percent of data in India indicates that a large proportion of the population remains highly susceptible to the novel corona virus.
Transmission expected to continue in most states
The report states that transmission of infection is expected to continue in most Indian states until the extent of herd immunity is achieved by natural infection or vaccination. While there is no information about the border right now, most estimates say it is more than 50 percent.
According to the report, one out of every nine people with no symptoms associated with COVID-19 was found to have SARS-CoV-2 antibodies. The report says that our data supports the expansion of testing strategy. These should include people who do not have symptoms. They found only 3 percent of sero-positive individuals with symptoms of COVID-19. This shows the limitations of testing due to symptoms. With this comes the importance of universal prevention measures.
The report has revealed that one in 15 people, aged 10 years or more, had SARS-CoV-2 infection by August 2020. The adult’s seroprevalence increased 10-fold between May and August 2020. The proportion of infections and cases less in August than in May shows a good increase in testing across the country.
