This is all completely wrong. Varicella Zoster (aka the Chicken Pox virus) causes a period of hypercoagulability in adults which causes DVTs and pulmonary embolisms reasonably often. It's well documented, although most doctors are not familiar with it. So that part of the response is wrong. And the study it cites (a) does not support it's answer, and (b) is not relevant.

edit: this is the kind of wrong answer that can kill people.

Noted! I'll work on fixing the underlying problem, and more importantly I'll add bigger/better disclaimers to make sure nobody is taking these answers too seriously.

Right.

Obviously there's an NLP issue going on, where the "rare" in the quoted snippet is scoped to the complication under discussion.
