The great mystery of COVID-19: Being infected, why do some people die without symptoms?

Currently, the number of corona-positive cases has crossed the 1 million mark and the number continues to rise at an alarming rate. However, not all infected people respond equally to corona virus.

According to statistical data, patients have a wide range of symptoms and the exact reason for this phenomenon is still a big question. However, scientists have identified a number of factors that have certain effects on the symptoms of human disease.

Although the most common symptoms are fever, cough and shortness of breath, there are many cases in which the patient does not experience any of the above symptoms. A study of 204 patients in Hubei province, China, published in the American Journal of Gastroenterology showed that just over half of patients experienced gastrointestinal symptoms, such as loss of appetite, nausea, vomiting and diarrhea.

The New York Times reported that corona virus can sometimes affect the nervous system and cause seizures. In other cases, people with COVID-19 infection also experienced muscle aches and exhaustion.

In contrast, there are patients who are positive for the virus but have only mild symptoms or no symptoms at all.

So why does corona virus affect everyone so differently?

Kathryn Jacobsen, health expert at Yahoo News, said: “It can be hypothesized that humans are not machines. There are many factors that influence the body’s response to pathogens. For corona virus, the two most important factors seem to be age and health status “.

The effect of age on corona virus symptoms seems to be quite noticeable. “The way the body responds to infection changes with age. Anyone can get seriously ill and die from coronavirus, but the death rate is highest in the elderly.”

People with many underlying medical conditions are also susceptible to related symptoms. “People with heart, lung, diabetes or other illnesses are often more severely affected,” Jacobsen said. However, the direct correlation of some health problems and symptoms caused by COVID-19 has not been studied specifically.

Another possible reason is the level of coronavirus infection in patients. Writing in the New York Times, Dr. Joshua D. Rabinowitz and Caroline R. Bartman – two geneticists – said: “Just like a poison, the virus is more dangerous when the number is greater. For example, entering an office where a person who has been COVID-19-positive by passing is not as dangerous as sitting next to an infected person for 1 hours. “

For corona virus, it is still too early to know exactly what factors affect the health of a specific individual. According to Jacobsen, smoking, nutrient levels and chemicals in the body, the use of drugs and genes are all factors to consider.

People at high risk of hospitalization due to corona virus have been asked to increase vigilance to prevent infection. “However, that does not mean that people who are not at high risk do not need to protect themselves. Low risk does not mean no risk.”

“Since it is impossible to know for sure who will have mild symptoms when infected and who will have severe symptoms or death, the safest option is to follow the directions of local, state and national governments to protect yourself from corona virus “.
