Cholera update

Cholera is a bacterial infection, mostly transmitted through the consumption of water contaminated with the Vibrio cholerae bacteria. Outbreaks can occur periodically in any part of the world where water supplies, sanitation, food safety and hygiene practices are inadequate. Overpopulated communities, usually in the developing world, with poor sanitation and unsafe drinking water supplies are most frequently affected.
