Young and middle-aged people, barely sick with covid-19, are dying of strokes, by Ariana Cha.

Thomas Oxley wasn’t even on call the day he received the page to come to Mount Sinai Beth Israel Hospital in Manhattan. There weren’t enough doctors to treat all the emergency stroke patients, and he was needed in the operating room.

The patient’s chart appeared unremarkable at first glance. He took no medications and had no history of chronic conditions. He had been feeling fine, hanging out at home during the lockdown like the rest of the country, when suddenly, he had trouble talking and moving the right side of his body. Imaging showed a large blockage on the left side of his head.

Oxley gasped when he got to the patient’s age and covid-19 status: 44, positive.

The man was among several recent stroke patients in their 30s to 40s who were all infected with the coronavirus. The median age for that type of severe stroke is 74. …

Reports of strokes in the young and middle-aged — not just at Mount Sinai, but also in many other hospitals in communities hit hard by the novel coronavirus — are the latest twist in our evolving understanding of the disease it causes. The numbers of those affected are small but nonetheless remarkable because they challenge how doctors understand the virus. Even as it has infected nearly 2.8 million people worldwide and killed about 195,000 as of Friday, its biological mechanisms continue to elude top scientific minds. Once thought to be a pathogen that primarily attacks the lungs, it has turned out to be a much more formidable foe — impacting nearly every major organ system in the body.

The idea that COVID just attacks the lungs and is treatable using ventilators turns out to be only partly correct, and often wrong. It is also a blood-clotting disease that causes stokes and organ failures. There is neurological damage being reported as well. This virus has multiple ways of attacking the body, which is unusual. The suspicions that it came from a biowarfare lab are growing.
