Typical symptoms of cholera infection include stomach pain and rumbling, nausea and vomiting, with fevers being uncommon. The diarrhea caused by cholera contains a good number of the Vibrio cholerae bacteria, and it has the potential to affect other people, if ingested or if the bacteria spread to water or food. So high levels of sanitation are important to reduce the spread of cholera. It is extremely important to properly dispose of diarrhea and vomit from an infected person, regularly wash hands, and sanitize any contaminated items. Once recovered, people do not carry the disease, and also do not have immunity, meaning they can be reinfected if exposed to the bacteria again. The disease does not typically spread from person to person through casual contact.
