evidence: Doing an autopsy on a COVID-positive body is risky, but they had the special protective equipment and high-containment room they needed to do it. And maybe they could learn something that would help save some of the hundreds of thousands of people around the world who will fight COVID-19 for their lives in the months to come. [...] Marshall says that the risk of infection that this virus poses has changed how they perform all autopsies, regardless of whether the person was suspected to have COVID-19 or not. [...] That’s an important finding because ICU physicians in the Netherlands, New York and other places have been reporting that 20 to 40 percent of COVID-19 patients in intensive care have blood that clots abnormally. These doctors worry that tiny clots may be interfering with blood circulation in those sickest with coronavirus. That could be one reason the mortality rate among these patients is so high.
