The coronavirus virus is showing no signs of slowing the epidemic, reaching new countries and claiming more lives.
According to the World Health Organization (WHO), as of Friday, the virus has infected more than 972,640 people worldwide.
For herd immunity, it does not matter whether immunization comes from vaccination, or people who had the disease. Importantly, they are immune.
As more people become infected with COVID-19, the disease caused by the virus, there will be more people who recover and who are immune to future infections.
"But it doesn't have to be - and it won't be - that way," said Matthew Bialis, a professor at the Institute of Infection, Veterinary and Ecological Sciences at the University of Liverpool.
Reducing the number of people that infect a person - socially disruptive measures such as closing school, working from home, avoiding large gatherings and frequent hand washing - at which point herd immunity decreases , It can be reduced.
From an Epidemiology point of view, the trick is to reduce the number of people we're in contact with . so that we can reduce the number of contacts that we infect, and herd immunity starts earlier.

what is herd immunity?
Swarm immunity refers to a condition where enough people in a population are immune to infection that is capable of preventing that disease from spreading effectively.For herd immunity, it does not matter whether immunization comes from vaccination, or people who had the disease. Importantly, they are immune.
As more people become infected with COVID-19, the disease caused by the virus, there will be more people who recover and who are immune to future infections.
Will this slow down the COVID-19 epidemic?
With the new coronavirus outbreak, current evidence suggests that one infected person is infected between two and three others on average. This means that, if no other measures are taken, 50 to 70 percent of the population with immunity can kick in herd immunity."But it doesn't have to be - and it won't be - that way," said Matthew Bialis, a professor at the Institute of Infection, Veterinary and Ecological Sciences at the University of Liverpool.
