Many people who have tested positive for coronavirus do not show any symptoms, and according to a new study conducted by Peking University in China, the combined rate of asymptomatic infections was 0.25% in the tested population and 40.5% among confirmed cases, according to the “Times of India” website. In this report, we learn how to discover that you are silent carrier of corona You don’t show any symptoms.
The study published in JAMA Network Open found that asymptomatic infection could be a potential source of transmission of corona, due to the fact that asymptomatic people usually do not show symptoms or telltale signs, but are as infectious as asymptomatic carriers.
Scientists and doctors are still trying to understand how the coronavirus affects different individuals and why some have symptoms while others do not.
Why do some people show symptoms of corona and others do not?
While the elderly, those with pre-existing comorbidities, the immunocompromised, and the obese are at increased risk of severe symptoms and complications, some individuals have no symptoms at all. Why?
Researchers have been looking at this since the emergence of the virus, but they have not reached a firm conclusion. However, some theories have emerged. Experts believe that it is either due to the body’s stronger innate immune response to the virus or because some people are exposed to a smaller viral load.
Age is thought to be another reason behind asymptomatic coronavirus infection, as young people show much greater amounts of asymptomatic cases than older adults.
A Duke University study found that children aged six to thirteen years had the highest number of asymptomatic cases.
One theory behind this is that young people suffer from more respiratory viral illnesses in general, which is why by the time they contract COVID-19, it becomes less severe.
Some genetic differences have also been traced back to asymptomatic corona infection. For example, some people have different forms of the ACE2 protein that make them susceptible to coronavirus infection and complications. Thus those without these differences are less likely to develop symptoms.
Moreover, if you have had COVID-19 in the past or developed immunity caused by the vaccine, experts believe you may have an asymptomatic infection. This is also known as cross immunity, i.e. the idea of being exposed to a virus through infection or vaccination.
How do you know that you are pregnant with corona without symptoms?
There is no special way to tell if you have an infection without symptoms.
However, the only way to be sure of this is with a corona test.
Corona testing has become a very crucial step in the fight against the deadly virus. RT-PCR or a rapid antigen test can help determine the presence of the virus in the body.
But a person certainly may not be tested if they do not have symptoms. Hence, in case you are exposed to a confirmed case of corona, make sure to isolate yourself from others and get tested immediately until you get a negative test report and unless you do, stay isolated.
