Cholera is a bacterial infection that can cause severe diarrhea and dehydration. It is spread through contaminated water and food, and is most common in areas with poor sanitation and hygiene.

Cholera can be prevented through a combination of interventions, including improving access to safe drinking water and sanitation, promoting good hygiene practices, and implementing effective water treatment and distribution systems. Vaccines are also available to prevent cholera infection

Treating cholera requires prompt rehydration with oral rehydration solution or intravenous fluids, as well as antibiotics to kill the bacteria. Early treatment is critical to prevent severe dehydration and death.
