How Does the Herd Immunity Effective Against Coronavirus:
The scope of infection of the coronavirus started from China has now reached Africa through Asia, Europe. The number of deaths from this is increasing every day. Given the increasing infection of the coronavirus, governments in many countries around the world are engaged in an effort to stop it. While scientists are busy preparing its medicine and vaccine on the one hand, on the other hand, inexpensive test kits and equipment like ventilators are being made. Lockdown has been done in many countries of the world including India. People imprisoned in homes are wondering when the corona crisis will end! Meanwhile, a report has come that if people develop herd immunity, that is, it will prove to be important in combating corona.
It is known that diseases like polio and smallpox have also been defeated by increasing herd immunity through a vaccine. According to a report, Britain's Chief Scientific Advisor Sir Patrick Valence advised the government to reduce the impact of the coronavirus by spreading it to a large population, so that the 'herd immunity', a collective immunity, would develop and corona To be finished. However, the UK Health Ministry denied that no such decision has been taken by the government yet.
UK Health Ministry spokesman Matt Hancock has said that mass deterrence is a natural by-product of any epidemic. That is, with the outbreak of the epidemic, herd immunity develops in people on their own. The best example to understand herd immunity is polio. The whole world was frightened by this disease that disabled people, but almost all the population of the world including India has become immune from polio.
What is herd Immunity:
Herd immunity is a very old process of medical science, in which more than 60 percent of the population of the country has to be infected with the virus so that their body becomes immune to fight this virus and in the future, this virus infection will not spread in them. According to the Center for Disease Control and Prevention, herd immunity is developed by vaccination or infection. By adopting this, the chain of the spread of the disease in a society or group can be broken.
How does it work:
In order to develop herd immunity, the first way is to find out the spread of the disease and the necessary herd immunity limit. Epidemiologists use the RO, the basic fertility standard, to find the limit. This is called Basic Reproductive Number-R0. It tells how many more people can be infected by a single infected person. Based on this standard, its use can be further enhanced. According to the ICMR report, one person suffering from corona can infect the other four people. This number may also increase in community transmission.
How effective against corona:
Most people infected with corona are those with a weak immune system. This includes elderly patients with heart patients or BP patients. If vaccination is the method of vaccination, it may take a very long time. Infections can also be risky. According to experts, the same people can be included in this process, within which there can be continuous development of immunity. In this case, it may take too long to use herd immunity.
If there is pressure on scientists to adopt herd immunity against this dangerous coronavirus, then it will be able to do the right thing, there is no evidence nor inference can be made. British virologist (virologist) Dr. Jeremy Rossman says vaccines are not available to protect people against the coronavirus, so herd immunity may not be a good public health strategy. Other public health experts are also insisting on adopting preventive measures such as social distancing and cleanliness to protect people and themselves from their growing infection.
