Fortunately, this is such an exceedingly rare event (only the second documented case, if true), it becomes newsworthy.  Perhaps, it's a matter of the "exception proving the rule" on the great effectiveness of Pre-exposure prophylaxis (PrEP).

From the story:

A New York City physician has documented a case in which a male patient taking Truvada (tenofovir/emtricitabine) as pre-exposure prophylaxis contracted a rare, highly drug-resistant strain of HIV while apparently taking PrEP daily as prescribed.
 
This is the second such case of documented PrEP failure in a man who has sex with men (MSM), following the February report at the 2016 Conference on Retroviruses and Opportunistic Infections (CROI) in Boston of a Toronto MSM on PrEP who contracted HIV under similar circumstances.

I agree, only 2 cases just goes to show how effective PrEP is in the real world.
