Cholera is a bacterial infection in the small intestine that causes intense, watery diarrhea. Sometimes it can be so severe that a person becomes severely dehydrated and needs to be hospitalized in order to receive intravenous fluids and antibiotics.
The infectologist is a medical specialist and diseases caused by infectious agents such as bacteria, viruses, fungi and parasites.
Remember that for the proper selection of health professional that treats cholera you must consider the nature, severity and symptoms you are presenting.
