Herd immunity: The herd immunity is still far away for the countries battling the corona


Study claims - Heard immunity is far away, as percentage of infected in Corona affected countries is still in single digit

Herd immunity was considered an effective weapon to fight the corona

• Herd immunity was considered an effective weapon to fight the corona, but according to the latest studies, the herd immunity is still far away for the countries battling the corona. Because, in countries where corona is spread, the percentage of infected people is in single digits. Herd immunity is the level after which the virus cannot spread widely.
• There is no set standard for this, but according to experts, more than 60% of people must be infected for this. New York State, Public Health England, Carlos Health Institute and Sweden's Public Health Agency have done extensive research on this. According to this, the risk of infection still remains among the most affected cities.
• Countries like Sweden and Britain tried to increase the level of immunity in citizens by keeping a limited lockdown, but here also 7 to 17% people were hit. New York is the most affected in the US, with 20% of citizens infected in early May.
One study said that 10% of people wanting to return to work became infected.
• A study has been done in China about herd immunity, but no results have been found. A study of hospitals in Wuhan said that 10% of people wanting to return to work became infected. According to Epidemiologist Michael Mina of Harvard University's TH Chan School of Public Health, it is clear from all the studies that no country is likely to reach herd immunity recently.
• In the new test for corona, antibodies in the blood of people and proteins prepared by the immune system are being tested to fight infection. It can be detected in those who have infection but do not show symptoms. At present, the biggest challenge is to identify such patients from Corona.

Immunity can prove like a fire brigade to extinguish a corona fire

• Carl Bergstorm, a professor of biology at the University of Washington, explains that these studies cannot be fully grounded. But they can definitely find out how much coronavirus has actually spread and its potential. The range of herd immunity can be different everywhere.
• Because it depends on factors like population density and social interaction. Herd immunity may also arise in people regarding the corona, but cannot say how effective it will be in all cases, how strong it will be and how long it will last. At the same time, Dr. Mina says that immunity can work like a fire brigade in this disease.
