In 30 percent of people with advanced cases of the Corona virus, serious blood clots, according to medical experts.

Experts say strokes, also known as thrombosis, may contribute to the death of a number of patients.

One of the body’s usual reactions to the virus is the formation of these clots, due to acute inflammation in the lungs.

People with HIV around the world have multiple medical complications, some of which may be fatal.

Last March, as the virus spread around the world, doctors noticed a steep increase in stroke rates among hospital patients, usually contrary to what was expected.

They also noticed other surprises, including the discovery of thousands of small clots in the lungs of some patients.

Viral infection also increased deep venous thrombosis, which is the stroke of the feet.

This condition is considered a danger to life, if one of the clots separates from the veins of the foot and moves in the blood towards the lungs, to block the blood circulation in the upper arteries.

“Real trouble”

The artist, Brian McClure, was transferred to the hospital last month, after suffering from pneumonia caused by the Corona virus. But as soon as he arrived, he did the radiographic images, until he turned out to be facing a bigger battle to survive.

He says: “I showed the image of the lungs and the quality of blood clots in them, and I was told that it is very dangerous. Then I started to feel serious. I understood that if I did not improve, then I would be in real trouble.”

Maclor is now recovering at home.

“The past few weeks have carried an overflow of data, and it has become clear, I believe, that clotting is a major problem,” says Robin Aria, a blood clotting and blood clotting doctor at King’s College Hospital (London).

And the doctor adds: “The problems especially affect patients with covid in intensive care, as several recent studies have shown that half of them suffer from pulmonary embolism and blood clots in the lung.”

Dr. Robin Arya believes that the numbers of patients with advanced cases of Covid, who develop blood clots, may be about 30 percent higher than the data published in Europe.


Inside the hospital, the professor’s team of hematologists is analyzing patient samples that show how the Coronavirus changes their blood and becomes sticky, making it easier to form thrombosis. This change in blood viscosity results from acute inflammation in the lungs.

Professor Aria says: “In patients with advanced conditions, we notice a flow of chemicals in the blood, which has a harmful effect on stimulating blood clotting.” All of this leads to the deterioration of the patient’s condition.

According to Professor Beverly Hunt, a specialist in thrombosis, glutinous blood has wider ramifications than thrombosis, because it leads to higher rates of strokes and heart attacks. “Yes, sticky blood contributes to high death rates,” she asserts.

Blood thinners experiences

In addition to all these medical challenges, studies show that blood-thinning medications currently used to treat blood clotting do not always have the required effect. Also, increasing the doses of these drugs to higher levels is a risk for people who are exposed to potentially fatal bleeding.

According to Professor Arya, the balance is “precarious” between the treatment of clotting and causing bleeding.

Currently, there is a huge push for medical staff from all over the world to cooperate with a view to finding a safe and effective way to treat the problem of coagulation caused by the Corona virus.

Experiments are underway to find the typical caliber of blood thinners, for use around the world.

However, some experts believe that another possible solution is to find a way to reduce acute lung inflammation, which causes sticky blood formation, that is, to solve the source of the problem in the first place.
