I am a healthcare professional with some public health and sanitation training and worked/traveled in Africa, Asia quite a lot, especially in the lesser known destinatios. So for regular life? Not much. I do adhere to basic sanitary rules (cook it,peel it or leave it) and make sure the water I use is clear when I am in these areas. But otherwise just the normal stuff like washing your produce before eating it, washing your hands after having a leak,etc. In my daily life it is rather unlikely to come in contact with the really nasty shit. (okay, only when you work with raw chicken…that stuff is nasty)

But work-wise? I am an extremist in that regard. I still wear a mask when seeing patients (more out of fear that I might infect them unknowingly), I absolutely desinfect my hands as often as required, I adhere to sanitation rules (e.g. for putting in iVs) religiously and make my students do the same. And when I am a patient I absolutely make sure that staff does the same when treating me.

The reason for that is quite simple: I saw too many hospital acquired infections and had a minor one myself. And that is unnecessary - and the stuff you get there is the one to truely fear. That will fuck you up badly.
