About half of the 109 Covid-19 patients (ages 22 to 94) treated at Central Hospital of Wuhan, researchers there reported, developed acute respiratory distress syndrome (ARDS), in which fluid builds up in the small air sacs of the lungs. That restricts how much air the lungs can take in, reducing the oxygen supply to vital organs, sometimes fatally; half of the ARDS patients died, compared to 9% of patients who did not develop the syndrome.
