Abstract |
Two recent headline causing events have reinforced the concern about the spread of diseases through waterborne routes. These events include the current cholera epidemic in the Western Hemisphere that has caused more than 750,000 reported cases of cholera through April, 1993, and the more recent cryptosporidiosis outbreak in Milwaukee, Wisconsin where 370,000 people had watery diarrhea during the time frame of concern. The paper discusses the types of information gathered in three case studies from past suspected waterborne disease outbreaks and how the data were used to implicate water as a mode of transmission. |
