The coronavirus not only causes pneumonia but can also attack blood vessels throughout the body, leading to organ failure, according to a new study published in the medical journal Lancet.
“Viruses not only attack the lungs, but also attack blood vessels everywhere,” said Frank Ruschitzka, author of the study from the University Hospital of Zurich, according to the South China Morning Post .
The team found that the virus is not only causing pneumonia. “It invades the endothelial cell layer, which is the defense line of blood vessels, weakening the defense gland and disrupting circulation,” the smallest blood vessel, the author said.
This causes blood flow to the organs to decrease and eventually to stop blood circulation. Therefore, patients have problems in all organs such as the heart, kidneys, intestines.
That explains why smokers or those with underlying disease that have impaired endothelial function or unhealthy blood vessels are at risk from SARS-CoV-2.
The study, published April 17, found traces of the virus in endothelial cells (mucous cells inside blood vessels) and in inflamed cells, in Covid-19 patients. .
Although the study looked at only three cases, Ruschitzka said examination of other Covid-19 patients also found that blood vessel mucosa was “full of virus” and that vascular function was disrupted in all organs.
From these findings, the team proposed therapies to stabilize endothelial cells simultaneously to prevent virus replication.
In addition to finding a vaccine to prevent the virus from spreading, Ruschitzka said that promoting vascular health may be the most important in treating Covid-19 patients.
John Nicholls, a professor of pathology at the University of Hong Kong, thinks more research is still needed.
“While many structures may look like virus components under a microscope, other lab technologies will need to be conducted to really confirm the virus infection,” the South China Morning Post said . Mr. Nicholls.
- ‘The world is nearing the peak of the global Covid-19 spread’ – Coronavirus 2019
According to experts, the world is getting close to the peak of the global spread of Covid-19, and the disease is well beyond its current containment efforts.
Several countries affected by the Covid-19 epidemic are racing to prevent an outbreak, including Iran , Italy and South Korea .
Tedros Adhanom Ghebreyesus, director general of the World Health Organization (WHO), said Monday that the international community needs to act quickly before the “window of opportunity” for disease control is completely closed. .
Paul Hunter, a professor of medicine at the University of East Anglia, agrees with the warning Tedros issued, saying there is not much time to prevent the disease, according to the Guardian .
“Recently, the WHO director-general said that the door to the opportunity to control the disease is now closing. Every 24 hours, we are getting closer to the peak, after which we cannot prevent it. stop the global pandemic, “the professor said.
Mr. Hunter added that while the number of infections in China , the starting point for Covid-19, is decreasing, some other countries are “developing extremely worrying”.
The number of infections in South Korea has skyrocketed since the outbreak, according to Professor Hunter. “The identification of a major epidemic cluster in Italy is a major concern for Europe and we anticipate that there may be more confirmed cases in the next few days,” he said.
He said the situation in Iran was noticeable for the Middle East . “The deeper problem with the cases in Iran is the larger armed conflicts in the region,” he said.
Dr. Robin Thompson, an epidemiologist at Oxford University, pointed out that the number of infections in Italy doubled from February 21-22.
“This is an important stage of the corona virus outbreak. It is important to quickly isolate even minor illnesses in affected areas to prevent human-to-human transmission in Europe. And must follow public health guidelines, “Mr. Thompson said.
On February 23, President Moon Jae In announced that the Korean government had raised the national alert to the highest level, the red alert, according to Yonhap.
In Italy, the number of new strains of coronavirus infection has increased from 5 in the morning of February 21 to more than 130 in the morning of February 23, and there are now at least 152 people positive for the virus, according to official figures. .
