The country's capital Delhi is moving towards herd immunity from the coronavirus. Official figures from the Ministry of Health say that only 6.33 lakh people have been found infected with a corona in Delhi, but according to sources, a recent sero survey suggests that the total number of infections here could be more than one crore. In fact, last Sunday, Delhi's fifth solo survey has revealed the results, in which 50 percent of people have been found to be corona infected, that is, these people got hit by the coronavirus and then after recovering their body developed antibodies against this virus. Has gone.


According to media reports, under the fifth serosurvey, samples of 28 thousand people were taken in 11 districts of Delhi, out of which about 50 percent, ie 14 thousand people have been found to have antibodies against corona infection. Here is one such district, where antibodies against corona have been found in about 60 percent of people. Certainly, this result of the serosurvey indicates signs of herd immunity in Delhi.


What is herd immunity?

If a disease spreads to a large part of a population and people recover from it, then their body develops immunological properties against that disease. This helps prevent their disease resistance from growing. This is called herd immunity.


How many people must be infected to get herd immunity?

It is generally believed that 70 to 90 percent of the population needs to be immunized to reach the level of herd immunity, that is, they should have immunological properties against the disease. At the same time, according to Johns Hopkins University, to reach the level of herd immunity, about 80 percent of the population needs to be immunized.

Herd immunity can also develop with the help of a vaccine

Herd immunity can also be achieved through vaccination, which is being tried. According to the Ministry of Health, more than 1.6 million people have been vaccinated in India so far. The government plans to vaccinate around 300 million people by July.
