A study at the University of San Diego claims to have proof that COVID-19 is not a respiratory illness, but a vascular one.
This could explain blood clots in some COVID patients and other issues like “COVID feet”, which are not classic symptoms of a respiratory illness.
The study, published in the journal Circulation Research, shows with precision how virus damages the cells of the vascular system.
It was already known that besides the various symptoms of COVID-19 that coincide with respiratory problems, there are other cardiovascular issues that affect other parts of the body.
