Cholera / ETEC

Dukoral - Cholera / ETEC Vaccine for Travel

What is Cholera and ETEC?

Cholera is a highly contagious bacterial infection caused by the Vibrio cholerae bacterium, which can cause severe diarrhea and dehydration. It is mainly spread through ingestion of contaminated water or food (typically seafood).  

Enterotoxigenic E.coli (ETEC) is a type of bacteria that also causes diarrhea but does not have the same severity like cholera. It can be contracted in areas where sanitation and hygiene are poor or could occur from consuming contaminated or improperly cooked food.  

How to Cholera / ETEC?

Cholera and ETEC can be prevented by practicing good hygiene habits such as washing hands with soap and clean water, especially before handling food and after using the bathroom. Safe drinking water is essential in prevention of these illnesses; it is recommended that tap water be boiled or treated prior to consumption.  

Additional food safety measures include avoiding: raw or undercooked seafood, unpeeled fruits or vegetables that have been washed in contaminated water, and unpasteurized dairy products. 

Is Cholera / ETEC Vaccine Necessary?

Travelers should consult a healthcare professional for advice on vaccinations and preventative medication when planning trips to areas at risk for cholera/ETEC exposure. Dukoral, which is monovalent, provides protection against cholera, and some protection against traveler’s diarrhea. The WHO recommends vaccination for those traveling to regions where these diseases are prevalent.
