explaining cholera and how it spread consisted primarily of morbid poison entering the alimentary canal through means of contaminated water consumption. Snow believed this to be the basis of how cholera was contracted by individuals and believed improper sewage filtration was to blame as well as a means of spreading the disease from person to person.

People who work with sewage are at high risk‚ since the virus is always found in sewer systems (Kennamer). It can survive temperatures of 140° F for up to 60 minutes so sewage treatment isn’t always effective. HAV from unsuccessfully treated sewage can survive in oysters for five days‚ so contaminated oyster beds have caused outbreaks. It is especially a risk for oysters that are consumed
