Pneumonia virus can spread throughout the body, to the lungs, throat, heart, liver, brain, kidneys and intestines.
Published on May 13 in the journal Nature Medicine, a research team at the University of Hong Kong said the pneumonia virus can attack many different parts of the body.
This finding helps explain why the symptoms of people infected with Covid-19 appear in many parts of the respiratory system. This includes blood clots that cause strokes in young people, blockage of the dialysis system, headaches and even kidney failure.
Covid-19 is classified as a respiratory virus, spread through respiratory droplets, but it can still cause diarrhea and many other digestive symptoms. The researchers also found virus traces in the faeces of patients with Covid-19. This evidence shows that it can be transmitted through waste.
Researcher Jie Zhou and colleagues at Hong Kong University tried to find out how the SARS-CoV-2 virus can thrive in the gut. In laboratory samples in both bats and humans, the virus invaded many internal organs. Viruses not only live but also grow exponentially.
“The human intestinal tract may be the infectious route of SARS-CoV-2,” the research team said.
“A 68-year-old female patient had a fever, sore throat, high cough and diarrhea after being admitted to the hospital at Princess Margaret Hospital. We isolated the infectious virus from her stool sample. Here we have demonstrated that the virus replicates in organic matter in the intestinal tract, ”Zhou said.
In addition, another team at the University Medical Center Hamburg-Eppendorf (Germany) also performed autopsies of 27 patients who died of Covid-19. They found traces of the virus in many parts of the patient’s body.
The pneumonia virus is mainly active in the kidney, which explains the rate of kidney damage is usually higher than other parts in Covid-19 patients.
Infection with SARS-CoV-2 virus can make underlying diseases worse. Conversely, people with heart disease, diabetes and especially kidney disease will also be more vulnerable to the virus because of the lower ability of self-healing than healthy people.
