Critical if you get burned. Neosporin and silvadene cream are very handy. Use baby wipes to help cleanse the wound then bandage with ointment. Iodine-based disinfectant for scrubbing out wounds. Less potent anti-diarrheal medication but good for indigestion.
Foot rot and jock itch are significant problems.
Benadryl is good for allergic histamine release blockade. Good oral hygiene is critical. Good for applying antibiotic ointments to wounds. It may taste horrid but it beats a dose of amoebic dysentery. Good ones are expensive and almost all are heavy.
