Doctors still don't understand exactly how or why the coronavirus is causing blood clots.

Here are the coronavirus symptoms associated with blood clots.

Doctors treating coronavirus patients are seeing blood clots cause kidney failure, heart inflammation, and even immune system complications.

A study of the autopsies of 12 German patients who died of COVID-19 found that about 60% had undiagnosed deep-vein thrombosis — when a blood clot forms in a vein located deep inside your body, like the legs or arms.

Strokes occur when arteries carrying blood vessels to and within the brain get blocked (which clotting can cause), or when a blood vessel ruptures.

A Dutch study of 184 coronavirus patients in the ICU found that nearly one-third of them had blood clots.

Doctors have also reported clotting in the small blood vessels in coronavirus patients' skin, which causes rash-like patterns. .

Some experts believe the reaction may be due to small blood clots in the blood vessels of the feet?

"It's possible that this is a skin reaction or caused by a small clog or micro-clots in the blood vessels found in the toes," pulmonologist Humberto Cho told the Cleveland Clinic.

Scientists still aren't sure why COVID-19 is causing clots

According to Oxley, when the virus binds to ACE2 receptors in the walls of our blood vessels, the vessels become inflamed, which can cause clotting

"One of the theories is that once the body is so engaged in a fight against an invader, the body starts consuming the clotting factors, which can result in either blood clots or bleeding," Harlan Krumholz, a cardiac specialist at Yale-New Haven Hospital Center, told The Washington Post.
