Cholera is an intestinal infection caused by bacteria known as Vibrio cholerae. The main symptoms of this disease are diarrhea and vomiting. Transmission of cholera primarily occurs by consumption of contaminated food or drinking water. In the video, which can be used on smart phones, we describe several techniques that can be used to help prevent cholera, including methods of treating water, washing of hands, and seeking medical advice if/when one has the symptoms of cholera.
