Cholera is an infectious epidemic disease associated with the loss of large amounts of body fluids, so the mortality rates of this infection are high if not treated, especially when children and infants are infected, and people with weakened immunity, although Cholera is estimated to affect about 3-5 million people each year, causing more than 100,000 deaths worldwide, and cholera was common in the United States in 1800, but now it is. A rare disease, due to the remarkable development of living conditions and health systems, the cause of cholera is caused by the infection of the cholera bacteria, which was discovered by the German scientist. Robert Koch in 1883, where these bacteria live in shallow and salty water environments on microcrusties, and can exist in the form of colonies covering the surfaces of plants, rocks, and water.

Hypokalemia: Hypokalemia: Hypokalemia occurs in the case of cholera as a result of the loss of large amounts of blood with stools, and may affect the development of nerve and heart function, and can threaten the life of the injured.
Hypoglycemia: Children are the most likely to develop hypoglycemia as a result of low eating, and low blood sugar can be associated with loss of consciousness, seizures, or even death.
Kidney failure: a problem that can threaten the life of an injured person, as the kidney loses its ability to get rid of some electrolyte, body waste, and excess fluids.
