If there hadn’t been any cases of human infection in 30 years, can this really be explained by the cattle smuggling? Feels like something else must have changed

  They mention cattle illegaly raised in nature reserves. There may have been some surviving population of flies there.

    There was a 'barrier' somewhere between Mexico and South America where sterile male flies were regularly released. They outnumbered natives and stopped reproduction cycle. Till recently. Now without control flies spread north into their historical territory. With warming climate they can spread even further. Wiki has a bit of info on it: https://en.wikipedia.org/wiki/Cochliomyia_hominivorax https://en.wikipedia.org/wiki/Cochliomyia_hominivorax
