if you keep your nails trim, start using a probiotic before you leave, take babywipes so can clean your hands then that’ll help with illness. If you’re there for a while you’l prob get more accustomed- i was there for 6 months and didnt get ill then went to nepal and got an amoebic cyst :S when i went back with my gf for 2 months she didn’t get ill at all and i was ill most of the time (a hangover from my friend in my gut)
its still amazing though, honest!
