Researchers at the University of Oxford in the UK have published a preliminary study over the weekend that may teach about the sophistication of the corona virus by causing microscopic changes in recoverers in a way that will affect them in the long run and make treatment difficult.
The researchers, who followed 36 subjects (including a control group), show that in those who suffer from "long cube" (the phenomenon of long-term complications even after recovery from the virus), abnormal pathological findings sometimes appear that may explain why there is shortness of breath even long after That the virus is neutralized in the body.
Shortness of breath is one of the familiar symptoms of "Long Cubid", but current research explains what causes it, and in fact refutes the hypothesis that it is a by-product of other symptoms related to the effect of the virus.
According to the study's lead researcher, Dr. Emily Fraser, the study is the first indication that long-term cobid patients have defective lungs but because the changes are so small and difficult to detect, they may last for a long time.
The study may show that the virus produces a kind of abnormal finding inside the small parts of the lungs or pulmonary blood vessels, "she explained, although it is not yet clear what the clinical significance of the findings is. The study is still in its early stages While breathing with a special gas.
