When the pandemic hit the United States in late March, many hospital systems were too overwhelmed trying to save lives to spend too much time delving into the secrets of the dead. But by late May and June, the first large batch of reports — from patients who died at a half-dozen different institutions — were published in quick succession. The investigations have confirmed some of our early hunches of the disease, refuted others — and opened up new mysteries about the novel pathogen that has killed more than 500,000 people worldwide.
Among the most important findings, consistent across several studies, is confirmation the virus appears to attack the lungs the most ferociously. They also found the pathogen in parts of the brain, kidneys, liver, gastrointestinal tract, spleen and in the endothelial cells that line blood vessels, as some had previously suspected. Researchers also found widespread clotting in many organs.
