Coronavirus destroys lungs. But doctors are finding its damage in kidneys, hearts and elsewhere.

The new coronavirus kills by inflaming and clogging the tiny air sacs in the lungs, choking off the body’s oxygen supply until it shuts down the organs essential for life.

But clinicians around the world are seeing evidence that suggests the virus also may be causing heart inflammation, acute kidney disease, neurological malfunction, blood clots, intestinal damage and liver problems. That development has complicated the treatment of the most severe cases of covid-19, the illness caused by the virus, and makes the course of recovery less certain, they said.
