I don't know where to ask this, here's the deal:

Since I reproduced I'm taking my family to safe resorts. We've been twice to Sinai - once in Taba and once in Sharm El Sheikh. Both times ended up with us puking and shitting our guts out after a week. Something like that never happened anywhere else in Egypt or in rest of the world (East Africa, Caribbeans, South America, SEA etc.) and we exclusively eat hotel food and drink bottled water.

Was that just a bad lucks? Anyone knows something about some particular virus or bacteria in Sinai?
