Can You Get COVID-19 Twice?

It is as of now obscure whether an individual grows long-term immunity after recuperating from COVID-19.

Numerous clinical analysts believes that individuals who recoup from COVID-19 ought to grow generally vigorous resistance for at any rate a couple of months.

Researchers and public health authorities still do not know how the human immune system responds to SARS-CoV-2 and whether or not people develop long-term immunity after recovering from COVID-19.

Fears about a potential absence of immunity arose in response to ongoing media reports of individuals testing positive for COVID-19 after already recovering from the ailment. 

It is hard to state whether these people tested positive as a result of a second infection. While the chance exists, all things considered, distinguishable degrees of the infection stay in the body considerably after indications resolve.

The immune system wards off remote pathogens, for example, bacteria’s and viruses. Specific resistant cells, called B-lymphocytes or B-cells, distinguish proteins called antigens on the outside of attacking cells.

At the point when a B cell distinguishes another antigen, it causes the creation of proteins, called antibodies, that dilemma to antigens.

Once an antibody locks onto an antigen, it attracts other cells that destroy the target.

At the point when B cells produce another immune response, they can keep making a similar counteracting agent if a similar antigen shows up later on. This is called adaptive immunity. 

Hypothetically, individuals who get COVID-19 ought to develop corresponding antibodies. Nonetheless, it is hard to state at this phase how these antibodies will react to future disease.

Immunity offers insurance that reaches out past the individual level. At the point when adequate people have built up a powerful neutralizer reaction, extra advantages, for example, “herd immunity” become a chance.

Herd immunity occurs when a certain percentage of a population develops immunity to an infectious disease.

It not only the ones who are not immune to that particular virus, but it can also slow down and even stop the spread of infectious diseases.

It is said that a population can develop herd immunity in one of three ways:

  • When the mass population comes in contact with the disease and generates a fighting immune response.
  • Many people receive inactive or weak strains of the disease through vaccination.
  • A combination of both ways above occurs.

The bad thing is that it is believed that herd immunity will not stop the spread of coronavirus at the moment. It needs a vaccine which is yet to be developed. If we allow our mass population to come in contact with this deadly virus, it would could lead to hundreds of thousands of deaths. Older individuals and those with chronic health conditions have a higher risk of developing severe, life-threatening symptoms of COVID-19.

What Do Researchers Have To Say About This

It is said that Herd immunity may not be a feasible or safe option right now. But, researchers are trying to understand how the immune system reacts to SARS-CoV-2.

Luckily, it creates the impression that a great many people who contract SARS-CoV-2 contamination rapidly create antibodies.

Specialists from Shanghai released a primer report. The discoveries of the primer examination recommend that individuals can create shifting degrees of resistance to SARS-CoV-2.

Individuals must remember that this fundamental examination isn’t peer-checked on. The scientists behind this investigation assessed a little example of people with gentle COVID-19. Subsequently, their discoveries may not make a difference to the more extensive worldwide populace.

Specialists and public health specialists don’t have the foggiest idea of how the resistant framework responds to coronavirus or whether individuals who recuperate from COVID-19 grow long haul immunity.

In the meantime, experts suggest that people continue to take preventative measures, such as physical distancing and self-quarantining, if necessary.
