Whilst i totally appreciate that this issue may be causing concern let's look at it in black and white and without all the media frenzy...
Sadly 103 Mexican deaths
Mexican Population circa 110 MILLION!
It is affecting the tinyest speck of dust on the planet. I am 100% confident that the relevant authorities will contain this before it does indeed become an issue for Cancun-bound tourist's.
Just my humple opinion and take on things.
