Infectious and Parasitic Diseases

CONTENTS
Cholera
Cholera
is an infectious disease caused by the Vibrio cholerae bacteria. The vast majority of cases can be traced to water sources contaminated by human waste. The bacteria causes diarrhea which can lead to dehydration. The dehydration, combined with other chemical changes within the body, can cause death within five days of symptoms first appearing.
Plague
Plague
is a highly infectious disease caused by the Yersinia pestis bacteria, which is most commonly transmitted to humans by fleas from infected rats. In the mid-1300's, an epidemic of plague killed an estimated 25 million people in Europe over a span of five years.
Typhoid Fever
Typhoid Fever
is an infectious disease caused by Salmonella typhimurium bacteria. Relatively rare in areas with modern sanitation practices, it is a serious health threat in the developing world, especially for children. Worldwide, typhoid fever affects more than 21 million people annually, with about 200,000 people dying from the disease.
