Why do some people not have symptoms of corona while killing others?

Corona virus is the limit of society, with its small size that cannot be seen with the naked eye, Corona was able to haunt the whole world within months. Many countries rushed to take unprecedented precautionary measures to limit the outbreak of the Corona epidemic, which the World Health Organization described as the worst health crisis facing the world, so the study was suspended, the movement of citizens was restricted, the borders were closed by land, air and sea, in addition to the quarantine of millions ... and others.

The Corona virus, Covid 19, has resulted in the death of at least 73,139 people in the world so far since its appearance in December in China, specifically in the city of Wuhan.

This epidemic is transmitted from person to person through small droplets that are scattered when coughing or sneezing. So it is important to keep people more than XNUMX meter away. These droplets also fall on surrounding objects and surfaces, and when you touch them and then touch your eyes, nose or mouth, people can become infected as well.

The symptoms include fever, cough and difficulty breathing. However, the danger lies when a person is infected with the virus without experiencing symptoms or showing only minor symptoms.

5% appear on them

In this context, the specialist in bacterial and incurable diseases, Dr. Roy Nisnas, told the Arab News Agency, that "there are many diseases that we have picked up and we do not show symptoms, such as polio, and others," explaining that "95% of people do not show symptoms and 5% do not show them."

Nisnas added: “With regard to Corona, we do not yet know how many people do not show symptoms, we need more studies after and a blood test for antibodies, and at that time we know the people who have antibodies, how many people have been infected and how many have not.” They get infected, because immunity overcomes the virus most of the time.”

Various factors

In addition, he pointed out that “the incubation period of the Corona virus can vary from one person to another, and there are several factors, including the strength or weakness of immunity, the amount of the virus that entered his body, and thus the delay beams to appear.”

Regarding the danger of infected people without symptoms, he replied: “The danger is in the period in which they carry the virus without being aware of the issue, and therefore do not take their precautions and cause the infection to be transmitted to others. But if the virus has left their body, there is no danger after that.”

He also added, "There is still no definitive answer about whether there is a certain period for them to be virus-free, as there are studies that are taking place so far."

A specific blood group?

And about whether there is a particular blood group that is more susceptible than others to contracting the virus, Nisnas said: “It is said that o+ defends its condition more, but this is not certain. I do not imagine that there is a study confirming this issue.”

He stressed that people should self-quarantine for a minimum of 14 days, after which they are tested.

On whether the person who recovered from Corona should remain in quarantine, Nisnas said: “We have to wait two days, after which two consecutive examinations are performed, and if they are negative, in principle we allow the person to return to normal life,” but he indicated that “there are questions.” Also about this topic because there are people who have the virus re-emerging after a while.”

It is noteworthy that, according to the latest statistics, at least 73,139 people have died in the world since the emergence of Corona in December in China. More than 1,310,930 infections have been diagnosed in 191 countries and regions, according to official figures, since the outbreak of COVID-19 began. However, this number reflects only part of the real outcome, because a large number of countries do not conduct examinations except for cases that require transfer to hospitals.

Of these injuries, at least 249,700 people have recovered as of Monday.
