Some of the symptoms of so-called long-covid, the ailments that can persist for months after a Covid-19 infection, may be caused by inflammatory molecules trapped inside tiny blood clots, a scientist at South Africa’s Stellenbosch University said.
High levels of inflammatory molecules were found in micro clots in blood samples from people with long-covid, Resia Pretorius, a researcher at the university, said in a statement on Monday. The molecules contained fibrinogen, a clotting protein, and alpha(2)-antiplasmin, which prevents the breakdown of blood clots, she said.
