Vibro cholerae is a Gram-negative bacterium transmitted through feces and unsanitized water. The bacteria secrete a protein known as cholera toxin that affects the intestines, causing abrupt onset of watery diarrhea that lasts 4-6 days. If left untreated, death due to dehydration can occur within hours. The disease is particularly dangerous for children, pregnant women, and their fetuses, as it may cause premature labor and fetal death.
