Cholera is caused by the bacterium Vibrio cholerae and is not a viral infection. Vibrio cholerae infections are mostly caused by contaminated water and food. Cholera is mainly spread by patients and carriers, mainly through the digestive tract. Misuse of water and food contaminated with Vibrio cholerae can lead to infection. Flies and daily life contact can also lead to indirect transmission. It is common in summer and fall in China, and is commonly found along the coast. Cholera is mostly acute in onset, with clinical manifestations of massive diarrhea, vomiting, accompanied by dehydration, low blood potassium and other symptoms, and in severe cases, circulatory failure and acute renal failure can occur. Because of the strong transmissibility, once diagnosed, it should be strictly isolated and promptly treated. If you are suffering from cholera, you should be admitted to the hospital and treated under the guidance of a doctor.
