It is undeniable that the epidemicCovid-19 Over the past three years, there have been a large number of cases and deaths in all parts of the world. Over the years, there have been several violent outbreaks. With each wave, a new infected person spreads widely. The latest number of infected people worldwide is 618 million (as of September 21).
Still, some people are still “surviving fromaddicted to covid“Come every wave This could include healthcare workers who spend months working among infected patients. or even someone who sleeps with a sick partner, if you havehigh risk exposure But still survived the infection of covids for such a long time. You might be a group of people calledSuper Dodgers” which scientists may want to hear from you.
A team of scientists from COVID Human Genetic Effort is working together to find a link to the number of COVID-19 cases. in the United States through the prevalence of antibodies. by collecting information according to the report of “US Centers for Disease Control (CDC)” and set the experimental problem that “Can a person develop antibodies against SARS-CoV-2 from infection?”
An experimental study was then conducted in which tissue samples were taken of people who said they had never been infected with coronavirus. It comes from a commercial laboratory in the US. taken to examine and analyzeThe results (as of September 13) indicate that 57.7% of the samples tested were Have been infected with SARS-CoV-2 at least once but does not show symptoms
When narrowed to only those under the age of 18, it is estimated that 79% of the samples tested had been previously infected with SARS-CoV-2 but did not show symptoms.
The results of the study showed that There is a small number of people in the United States. that seems to be able to avoid infection (Here they are unaware that they are infected. because there are no symptoms) So why is that? For this answer, scientists analyzed two reasons:
first There is a chance that people who believe they have never been infected with COVID-19 will suffer asymptomatic infection without knowing which researchers consider to be very common and undoubtedly likely to occur.
Second There may be genetic factors involved. Since the beginning of the pandemic It is clear that COVID-19 can make some people seriously ill while some people have flu-like symptoms. And some people hardly notice any symptoms at all, which varies from person to person. can be caused by many reasons But the most important factor is probably genetics.
When considering the reasons in the second paragraph more deeply, it is found that Large-scale international research has discovered 13 genetic code points in the human genome. linked to the sensitivity and severity of illness in people with COVID-19 It found that up to 20% of people have genetics that react strongly to coronavirus.
While some people, although infected with COVID as well, do not show any symptoms. or have few symptoms Studies have found thatThese people have a gene called “HLA-B*15:0” in their body cells. They are more likely to be infected with COVID-19 asymptomatically.
As a result, a team of scientists believe it is possible that some people are naturally immune to COVID-19, while not previously immune to COVID-19. They therefore want to study and find answers to the genetics of COVID-19. to understand that How does the genetic foundation of our immune system influence COVID-19?
They are also particularly keen to contact people who have not had any symptoms of coronavirus once. Despite repeated exposure to high-risk COVID-19 patients A team of scientists believe they will gain invaluable knowledge. About tackling COVID-19 that is still spreading around the world now According to the study, these people appeared to be resistant to infection.
“This discovery will allow us to develop new methods. in the fight against this epidemic through better and faster diagnosis This led to the development of new drugs for the treatment and prevention of infections. including new ways to develop vaccines and a better understanding of how infections work in the body; andTo achieve all these goals We need your help urgently.” said the COVID Human Genetic Effort team.
