Months into the pandemic, there is now a
growing body of evidence to support the theory that the novel corona virus can
infect blood vessels, which could explain not only the high prevalence of blood
clots, strokes, and heart attacks, but also provide an answer for the diverse
set of head-to-toe symptoms that have emerged.
In a paper published in April in the
scientific journal The Lancet, Mehra and a team of scientists discovered that
the SARS-CoV-2 virus can infect the endothelial cells that line the inside of
blood vessels. Endothelial cells protect the cardiovascular system, and they
release proteins that influence everything from blood clotting to the immune
response. In the paper, the scientists showed damage to endothelial cells in
the lungs, heart, kidneys, liver, and intestines in people with COVID-19.
