Herd Immunity Needed To Combat Corona Virus Infection

Ujjain 04.05.2020. Herd Immunity Is the only Iasting solution to the Coronavirus .There is no alternative to herd immunity.
In a nation of 1.3 billion people the herd immunity strategy, would allow a majority of the population to gain resistance to the virus by becoming infected and then recovering, could result in less economic devastation and human suffering than restrictive lockdowns designed to stop the virus.
No country can afford a prolonged period of lockdowns, and least of all a country like India – A Prominent  Epidemiologist and Indian Federation of Hospital Administrator, Executive Member, Dr Naresh Purohit told Blue Eyes.
Dr. Purohit, who is also Advisor, National Integrated Disease Surveillance Programme, stated that we  may be able to reach a point of herd immunity without infection really catching up with the elderly. And when the herd immunity reaches a sufficient number the outbreak will stop, and the elderly are also safe.
“The lockdown would have limited impact on the spread of the
Coronavirus, preventing
only 20-25% of infections that might eventually be detected at the peak of the pandemic.”averred the physician
Dr Purohit  expressed concern that the lockdown has caused “economic hardship ”, “pain and suffering ”, particularly for the poor.
The Physician pointed that in a lockdown we are not confronting the virus but simply trying to hide from it. Once the lockdown is lifted, the virus, which has not disappeared, will hit us again. The only way a lockdown can be an effective defence against the virus is if it continues for twelve months  or more till a vaccine is discovered. But that is a prospect which seems unfeasible.
Dr Purohit explained that herd immunity means allowing India’s young population to expose themselves to the virus and build up immunity.  Approximately 70% will have to acquire immunity for herd immunity to be effective. At that point, it will also cover the elderly, who are most at risk.
“In trying to build herd immunity, India has a great advantage over countries like the US, the UK, Italy, Spain and France because of the age profile of its population. Close to 90% of Indians are under 60. The experience of the virus in all other countries has established that people under 60, because of their resilience, either do not get infected or are infected only sub-clinically.” added Dr Purohit
However, a small percentage of this age group will develop the disease and an even smaller fraction of them will die (which in India may still amount to a few lakh people). Dr Purohit  apprehended that this is  the cost that has to be paid to keep the rest of India safe. He accepted this is the sacrifice  India is asking of its young population so that the country as a whole can survive.
Dr Purohit averred  two very important concerns need to be borne in mind as India attempts to build herd immunity.
First, the elderly have to be protected by isolating them from the young.
He observed that in India where, in urban slums or villages, families live together in one room, it would be difficult to separate from the young but this needs to be tackled innovatively. In rural India, the elderly could be encouraged to sleep outdoors. In slums, the percentage of the population over 60 is very small. “Unlike rich Indians, poor Indians do not live long lives,” averred Dr Purohit about the sad reality of India.
Second, Dr Purohit said that while going for herd immunity, every attempt must be made to ramp up the country’s health facilities. He added that if the elderly are protected, then the health facilities as they are should be able to handle the small number of younger people who fall ill and ensure their treatment and survival.
Dr Purohit stated that whilst India tries to build herd immunity, big gatherings must continue to be banned. This means cinemas , theatres (multiplexes), malls, gyms and restaurants must stay closed.
