ALERT: Study Shows Blood Clots Fill Lungs of Black COVID-19 Victims

You may not hear much about blood clots, but they are a serious health condition that can even be fatal. Deep vein thrombosis, or DVT, is a blood clot that forms in a vein deep in the body. Blood clots occur when blood thickens and clumps together.

These clots can happen anywhere in the body, but usually occur in the lower leg or thigh.
