ETEC (Enterotoxigenic Escherichia Coli)

Escherichia coli (E. coli) is a bacterium that normally lives in the intestines of humans and animals. Most types of E. coli are harmless, however some cause disease. Enterotoxigenic E. coli (ETEC) is the most common cause of diagnosed travelers’ diarrhea. It is also a major cause of diarrheal disease in developing countries, especially among children.

Ebola

Ebola virus disease (EVD) is a serious illness that is often fatal in humans. The Ebola virus was identified during an outbreak in Zaire (now the Democratic Republic of Congo) in 1976. Once in humans it can spread very easily to others by direct contact with the bodily fluids of a living or deceased person who had Ebola, and through contaminated surfaces and objects.

Campylobacter

Bacteria of the genus Campylobacter, enteric pathogens, causes the zoonosis infection, Campylobacteriosis. Campylobacteriosis causes 25% of traveler's diarrhea and is extremely widespread, especially in countries without proper sanitization.  Diarrhea in American military alone, from diseases such as Campylobacteriosis, has caused medical costs totaling over 124 million dollars.
