WSJ Feeling ill? The cause might be years old.

The link between new health problems and your past health history appears to be particularly prevalent with Covid. A new Nature Medicine study found that health problems stemming from even mild Covid infections can emerge as many as three years afterward. The study found a greater risk three years later of problems in the gut, brain and lungs, including irritable bowel syndrome, mini-strokes and pulmonary scarring.
