<em>The USA had three serious epidemies of cholera, which is an intestinal infection. It happened between 1832 and 1866, the pandemic began in India, and swiftly spread across the globe through trade routes. New York City was usually the first city to be infected. They estimated that two to six americans died per day during the outbreak. The end of cholera's outbreak is unclear, but researchers believe that it was related to quarantines or climate changes. The last cholera outbreak in USA was in 1911, the scientists found out that the effective treatment included antibiotics, zinc supplementation and rehydration.</em>
