new Delhi: National Capital Delhi (Delhi) And Mumbai (MumbaiIn sero surveys ()Sero surveysCorona virus (in)Coronavirus) In the hope of protecting the epidemic at the community level, scientists have said that the collective immunity against Kovid-19 in the country (Herd immunity) Looking at many socio-economic groups, it can develop in some areas only and can stay for a short time instead of long.
Let us know that herd immunity develops when in general 70 to 90 percent of people develop immunity against it after suffering from an infectious disease. But as far as the Novel Corona virus is concerned, there are many issues due to which there is no consensus on this subject.
Shahid Jameel, CEO and Virologist of the Wellcome Trust / DBT India Alliance, said, “There are no clear data that can tell how much of the infected population will develop herd immunity.” Many epidemiologists believe that it will be around 60 percent for SARS-COV-2. He said that herd immunity will be achieved at different times in different parts of the country.
A recently published research in the journal Science has revealed that herd immunity against Kovid-19 can be achieved even with a lower number of infected people than previously estimated.
“Herd immunity is determined by how many people in the population have developed immunity to an infection,” says Upasana Ray, Senior Scientist and Virologist at CSIR-IICB, Kolkata. It develops indirect immunity in those people of the population who have never been exposed to infection. This definitely means that the more people get infected and develop immunity, the lower the risk of getting infected by the rest of the population.
Satyajit Rath, a disease immunologist at the National Institute of Immunology, New Delhi, says, “In India, where there are socio-economic groupings, herd immunity is more likely to develop in different parts of the country rather than develop together.” It may not last long. ‘
