Some patients with corona may develop microscopic blood clots, and the small clots that form during the initial infection with the Covid virus usually dissolve naturally, but they may persist in long-term Covid patients.
What prediction did Bill Gates make for the future? And how does long-term Covid exhaust the body? How does corona affect the brain, blood circulation and lungs? What is its relationship to microscopic blood clots?
Bill Gates heralds a decrease in the risk of “Covid” and warns of a more dangerous pandemic
We start with the founder of “Microsoft” Bill Gates, who said that the risk of severe Covid-19 infection has decreased significantly, but warned of the possibility of another pandemic caused by a different pathogen, according to a report in the “The Hill” website ( the hill).
In an interview with CNBC’s Hadley Gamble at the annual Munich Security Conference in Germany, the billionaire said the novel coronavirus has spread through enough of the population that “risks are greatly reduced by this exposure”.
The Omicron variant was first discovered in South Africa and spread like wildfire in the United States after it was discovered around the holiday season. Gates said that the strain, known to cause less serious disease but still highly contagious, “overcame” health officials who gave vaccines to the public and individuals who had previously been infected, yet “the risk of serious disease, which is mainly associated with the elderly and obesity or Diabetes, it’s reduced dramatically now due to exposure to infection.”
But Gates warned that there are a lot of viruses in the world, and that another pandemic is likely to be from a germ in the coronavirus family.
“There are a lot of diseases,” he said. “We will have another pandemic. Next time there will be another pathogen.”
Other researchers also said another pandemic is likely to be around the corner, including the Center for Global Development.
Gates explained that there are two solutions to approach the next epidemic if the world learns from fighting the Corona virus.
“The first solution is to make sure that the available quantities (of vaccines) are allocated in a more rational way, and the second is to have a lot of capacity so that you can provide all of humanity with two doses in a very short period of time,” he said.
Gates called on the world to invest now in ways to prepare for a future pandemic. He added that producing enough vaccines for the world “must be what we aspire to.”
Public health experts have warned against declaring the pandemic over, but countries are largely abandoning mask mandates and COVID-19 restrictions, or planning to drop them as case numbers decline.
How does long-term Covid exhaust the body?
Millions of people still experience fatigue, cognitive problems and other long-term symptoms after they recover from the coronavirus, and the exact causes of the disease, known as long-term COVID-19, are still unknown.
In a report published by the American newspaper ” The New York Times “, writer Josh Keeler says that new research provides evidence explaining the effects that the disease has on the body and why it can be so debilitating.
Long-term COVID diagnosis
The writer says that patients with highly contagious coronavirus may end up in hospitals or on ventilators until their symptoms are diagnosed, and the negative effects on the body as a result of the severe Covid virus, which include pneumonia, low oxygen level and inflammation, usually appear in traditional diagnostic tests.
The writer explains that long-term Covid is different; It is a chronic disease with a variety of symptoms, which are difficult to diagnose using conventional laboratory tests; The difficulties in diagnosing the disease led to their symptoms being misdiagnosed as psychosomatic, but researchers who delved into the diagnosis of Covid patients for a long time found clear dysfunction throughout the body.
Circulation and Covid
The writer says that many long-term Covid patients had difficulties with physical activity long after the initial injury, and they also suffer a relapse if they exercise, as preliminary studies indicate that circulatory dysfunction may impair the flow of oxygen to muscles and other tissues. , which limits air capacity and causes extreme fatigue.
One study, according to the author, says that patients with long-term Covid symptoms had unexpected responses to riding a bike, despite the safety of their heart and lungs, their muscles were only able to extract part of the normal amount of oxygen from small blood vessels while they were driving. bicycle, which significantly reduced their ability to exercise.
The author explains that one possible reason for this condition is that chronic inflammation may lead to damage to nerve fibers that help control blood circulation; Damaged fibers are associated with dysfunctions such as heart rate, breathing and digestion, which is very common in long-term Covid patients.
microscopic blood clots
The writer refers to another problem that South African researchers found in the circulatory system, which is microscopic blood clots, as small clots that form during the initial infection with the Covid virus usually dissolve naturally, but they may persist in long-term Covid patients, and these clots can block the capillaries. The tiny blood vessels that carry oxygen to tissues throughout the body.
The author continues, saying that inflammatory substances called cytokines, which are often elevated in long-term Covid patients, may infect the mitochondria that supply the cells of the body with energy, making them less able to use oxygen, and the walls of blood vessels may also become inflamed, limiting the absorption of oxygen.
The brain and corona
In his report, the author states that even people with mild cases of Covid can suffer from persistent cognitive impairments, including decreased attention, memory and word-finding; According to Dr. Avindra Nath, clinical director of the National Institute of Neurological Disorders and Stroke, the potential long-term neurological problems of Covid constitute a major public health crisis, and researchers have found a wide range of dysfunction in the brains of long-term Covid patients.
The writer notes that although it is unclear how often the virus directly penetrates the brain, it appears – according to the researchers – that a mild infection causes significant inflammation in the brain.
A research group has also found that long-term Covid-19 may significantly reduce the amount of blood that reaches the brain, a finding that has also been seen in patients with chronic fatigue syndrome.
Lungs and Covid
Shortness of breath is a frequent symptom of long-term Covid patients, but common lung tests often return to normal. A team of British researchers has found preliminary evidence of lung damage in a small group of long-term Covid patients who have never been hospitalized; The detailed lung function survey indicated that most patients consumed oxygen less efficiently than healthy people, even if their lung structure appeared to be normal, and the researchers cautioned that a large group of patients would be needed to confirm these findings.
