In adults of 74 years old and
above, death rates for diarrheal diseases are five times greater. Diarrhea is
caused by infectious organisms, which include bacteria, viruses, protozoa, and
helminths. These organisms are transmitted from the stool of one individual to
the mouth of another. (fecaloral transmission).
I THINK humid but I'm not completely sure
Clear,clean water because when you Hand sanitized you need clear clean water.
Hope this help!
Have a good day:)
