First off, it doesn't matter where we go or how far we travel, we all have specific issues that worry us...Bathrooms, cleanliness, hydration, disease, medications...
Some of us are more susceptible than others to diseases and dehydration. Others are just as if not more resistant than the coloned people out there.
It just depends on your physical condition before you leave and where you are headed.
I have traveled a lot and all around, with my k pouch (a whole extra set of complications...irrigation, intubation, being able to sit down...) and have a pre-prepared kit with me at all times.
I carry a mini pharmacy with me including hand sanitizer, wipes, sterile wipes (they aren't all sterile!), antibiotics and antibiotic creams, neomedrol, various strengths of pain meds and NSAIDS, sometimes a few stronger meds like tramadol, antihistamines for allergic reactions, different sorts of bandages, ACE bandages for mild sprains, steri-strips and disinfectants for cuts, blister bandages etc
I usually only use the really unexpected stuff.
Like breaking a tooth or popping out a filling while away.
Or getting an abscess where I really don't want one (use the blister bandages over those, they work miracles!)
The only time that I caught a really nasty virus that had me throwing up my guts on a 20hr flight home was in San Francisco! It lasted for 35 days. I was so dehydrated by the time that I landed in Paris that I couldn't walk off of the plane on my own.
So if you have the chance to go to Africa, Go! Just take the necessary precautions.
And do not forget to have fun and take pictures!
