People traveling in the wilderness can acquire infectious diseases. These can be caused by organisms such bacteria, viruses, protozoans, or fungi. They can be transmitted through drinking contaminated water, or by transmission from one person to another.
Does anyone know of any reliable, quantitative data comparing the probabilities of getting different infectious diseases while hiking in the wilderness?
Quantitative doesn't mean it has to be high precision -- even order of magnitude numbers would help in sorting out what are the more important risks. It would be good to differentiate symptomatic infections from asymptomatic ones, and to avoid data that are confounded by a normal background rate of infection. (E.g., giardia has a 3-7% prevalence in the US, and is almost always asymptomatic.)
