Coronavirus Variants: Is there a way to know if you are an asymptomatic COVID carrier?

The SARs-COV-2 virus has proved to be extremely unpredictable and mysterious in many ways. The same virus that has claimed so many lives, sometimes, triggers no response whatsoever is people who are also called asymptomatic.

While there is no exact reason behind why some people develop symptoms and others don’t, according to many theories and experts, 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.

Innate immunity is something that we’re born with, a defense system that protects against all antigens. Some people are believed to have a strong innate immune response, which is the first line of defense. The virus fails to even reach the adaptive immune system which is composed of targeted antibodies. That said, having a strong innate immune system is extremely crucial. This explains why people with compromised immunity, diabetes, obesity and other chronic illnesses fall under the high risk category.

Additionally, how much virus you’re exposed to may also play a role in determining whether you’ll develop symptoms or not. Studies have found that those exposed to high viral load have had more distressing symptoms than those with low viral load exposure.
