EEIP RIDRM Cholera

 

Cholera is an acute diarrheal illness caused by enterotoxins produced by Vibrio cholera bacteria. Illness occurs when bacteria, in contaminated water or food, are ingested. Although rare in the United States, cases have increased globally since 2005. It is important for travelers to know where cholera cases occur. A vaccine (Vaxchora) is available that prevents severe diarrhea caused by most common type of cholera bacteria.
