Inflammatory Cells Trapped Inside Microscopic Blood Clots - Long COVID - South Africa Study

"Lingering COVID-19 symptoms in “long haulers” may be caused by an overload of inflammatory cells “trapped” inside insoluble microscopic blood clots, according to researchers at Stellenbosch University in South Africa."
"The researchers also noted a significant discovery, that the samples of blood plasma collected from acute COVID-19 and “long COVID” patients continued to deposit insoluble pellets at the bottom of the tubes of samples."
