According to light articles, a “light zero” coronavirus can affect many other organs, including the heart and blood vessels, kidneys, intestines, and brain, the magazine article said. the science,
2.4 million people have already become ill in the world, and more than 165 thousand people have died.
“A disease can affect almost any part of the body with devastating consequences,” said cardiologist Harlan Krumholtz from Yale University and Yale University Hospital in New Haven, USA. “His ferocity is impressive.”

Blood coagulation
According to experts, with coronavirus blood coagulation turns some mild cases into life-threatening emergencies.
Is there an excessive immune response behind the worst cases? Can immunosuppressive treatment help? How do you explain the surprisingly low levels of oxygen in the blood that some doctors observed in patients but did not breathe? Here are some of the questions that scientists are trying to answer.
Magazine the science explains how the virus develops rapidly and fatally in approximately 5% of patients who are seriously ill.
Immune attack system
Some doctors note that many patients are seriously ill from an over-reaction of their immune system, known as the “cytokine storm,” which is known to cause other viral infections.
“The true morbidity and mortality from this disease is probably due to this disproportionate inflammatory response to the virus,” says Jamie Garfield, a pulmonologist who treats patients with COVID-19 at Temple University Hospital.
However, other doctors are not convinced of this theory.
“It seems that there has been a rapid movement to link COVID-19 to these hyperinflammatory conditions. I really did not see any convincing evidence that this is so, ”says Joseph Levitt, a resuscitator in pulmonary therapy at the Medical School of the Medical University. Stanford
Heart damage
In Brescia, Italy, a 53-year-old woman had all the classic symptoms of a heart attack, but tests showed that the patient had COVID-19.
“How the virus infects the heart and blood vessels remains a mystery, but dozens of works have already confirmed that such damage is common,” he says. the science,
Infection can also lead to a narrowing of blood vessels. There are reports of ischemia in the fingers and toes, a decrease in blood flow, which can lead to swelling, pain in the fingers and tissue death.
Possible symptoms of coronavirus
Loss of taste and smell, conjunctivitis and dermatological wounds are other possible symptoms of coronavirus.
In addition, according to another study, 27% of 85 hospitalized patients in Wuhan suffered from kidney failure.
“The lungs are the main battle zone. But part of the virus may be affecting the kidney. And just like on the battlefield, if two places are attacked at the same time, each gets worse, ”says Hongbo Jia, a neuroscientist at the Suzhou Institute of Biomedical Engineering and Technology of the Chinese Academy of Sciences.
Brain and intestines
Other unexpected symptoms found in patients with COVID-19 focus on the brain and central nervous system.
Neurologist Jennifer Frontera of the Langone Medical Center at New York University, who has treated thousands of patients with COVID-19, said the science Neurologists are required to evaluate 5 to 10 percent of patients with coronavirus in their hospital.
According to him, “there is probably a huge underestimation” of the number of patients who have brain problems, especially because many are in a state of sedation and ventilation.
In early March, a 71-year-old woman from Michigan returned from a Nile River cruise with bloody diarrhea, vomiting, and abdominal pain. Although doctors initially suspected that she had a common stomach virus such as salmonella, the patient later developed a cough.
Doctors performed a PCR test with a nasal swab, and the result was positive for coronavirus. His case adds more evidence that the new coronavirus, like its cousin SARS, can infect the mucous membrane of the lower digestive tract.
Latin American Confirmation
The new data coincides with the diagnoses made by some doctors in Latin America.
In Chile, Dr. Sebastian Ugarte, head of the intensive care unit of the Clinic named. Indisi warned on social media that “now new signs appear on the skin” as symptoms of a coronavirus.
Ugarte attached a series of images to accompany his warning on Twitter.
At the same time, in Paraguay, the director of the National AIDS and STI Program in Paraguay, Dr. Nicholas Aguayo, in his social networks reported on the case of a young patient “due to significant nosebleeds and gingivorrhage (bleeding in the gums).” He noted that he had never had a fever, sore throat or cough.
During a physical examination, he said, in addition to bleeding from the nose and gums, he had “petechiae and ecchymoses on the skin, that is, purple activity (skin spots).” The rest of the medical examination was normal.
He noted that routine laboratory tests did not show anything surprising. However, a blood test showed “peripheral pancytopenia”, that is, a decrease in blood cells. In this regard, doctors diagnosed with immune thrombocytopenic purpura, which was confirmed after further examination.
“However, it attracted my attention that there were a lot of dysplastic disorders in the bone marrow cells, as if an important virus had acted on it,” the doctor said, so the patient was examined for COVID-19. which was positive.
“This case is extremely important for healthcare providers because it exhibits an atypical form of manifestation, such as a hemorrhagic disease, and without any initial signs of a respiratory manifestation,” Aguayo said on his social network Twitter.
“Of course, the virus caused immunological chaos in the patient and manifested itself as immunological thrombocytopenic purpura,” he concluded. The patient finally recovered.
