Bacteria are simple, single celled
organisms that may also exist in colonies. These microorganisms perform
many important functions in nature and some of them also cause diseases.
Examples of the waterborne diseases caused by bacteria are:
- cholera – in severe cases, can cause death within hours
- traveler’s diarrhea
- typhoid fever – can persist in the body, making survivors
Cholera and traveler’s diarrhea are typically treated by replacing
the fluids and salts lost from the body and sometimes antibiotics are given to shorten the duration of the symptoms. Vaccines are available
to prevent typhoid fever and antibiotics are given to persons who
have been infected. As with viruses and waterborne disease, maintaining
good public health practices is the best prevention.
