A lot of people mention cases like these, I'd like to see some figures, also taking into account that pulmonary problems and fatigue, for one, are common to other diseases (even treatable ones).
To be clear: I have no interest in downplaying severe effects of this infection. But I want to look at the whole picture.

Note that the JAMA editorial acknowledges the need for further studies, because the numbers are very small (compared to the known number of patients):
> We wish not to generate additional anxiety but rather to incite other investigators to carefully examine existing and prospectively collect new data in other populations to confirm or refute these findings.
Which is AFAICS the crux of the matter. No one knows how widespread these problems are.
