<unk>  is "caused by drinking water or eating food contaminated with the<unk>  bacterium. In an epidemic, the source of the contamination is usually the feces of an infected person that contaminates water and/or food. The disease can spread rapidly in areas with inadequate treatment of sewage and drinking water". This is an extremely important factor of how the<unk>  epidemic was able to spread throughout the city of<unk> , KY. There were 7,000 people living in this city and clean water was not a main priority in the 1800s. It is important to note that there were usually wells that farmers and slaves got their water from. These wells were shared by many which made the<unk>  epidemic nearly impossible to prevent.
