This approximate article in this approximate form is recycled every few years with no real evidence to back it up as an independant mental illness. I don't dispute that pop culture misrepresent any number of real life places and experiences. But roughly 1 in 1600 people will experience a psychotic episode in any given year. That a small handful get diagnosed, perhaps for the first time, during vacation isn't any cause for alarm or special diagnosis. It's even less surprising that the prevalence of this comes from countries where mental health issues are under diagnosed and overly stigmatized-- when the person coincidentally has an episode during vacation in a place with more progressive views of mental health they finally get recognized.
