What causes asymptomatic covid 19 infection? When COVID-19 hit, it was an unprecedented time for the world. You know what you went through; we all know what we went through.
One was not aware of the consequences the virus could produce for the human race.
Everything was in the city, but as days passed, more details unfolded with time. A new study reports a link between the presence of a genetic mutation and asymptomatic cases of COBIT 19.
Now it reveals that some people, even when they contract the COVID-19 virus, are twice as likely to not develop symptoms.
If a particular genetic variant is present in their body, it further States If people have two copies of this variant, they are eight times more likely to never develop any symptoms of covet.
Nearly 30 000 people participated in the 15-month study in the United States. The genetic variant is an HLA mutation in humans. Leukocyte antigens are a group of genes that protect one against infectious diseases.
These genes encode proteins that allow our body to identify invading pathogens. The presence of this specific variant pushes immune systems to quickly track down and destroy viruses that cause covert 19. Now humans carry two copies of HLA genes, one from each parrot.
These genes can have certain mutations that determine how susceptible a person is to a particular viral infection.
Research suggests that during the pandemic, at least 20 percent of the millions of covert infections were asymptomatic.
Now that these asymptomatic cases pose a major problem to curb the spread of the virus, they unknowingly contributed to the transmission of the infection as they were difficult to identify and therefore isolate, according to experts.
These findings can help in the development of the next generation. COVID-19 vaccines that not only reduce disease severity but also prevent symptoms.
