cholera
Cholera () is an infection of the small intestine by some Strain (biology), strains of the Bacteria, bacterium ''Vibrio cholerae''. Symptoms may range from none, to mild, to severe. The classic symptom is large amounts of watery diarrhea last ...
, Colwell discovered that cholera can lay
dormant in unfavorable conditions and then resume normal functions when conditions are favorable again.
Many of her research papers have focused on abating the spread of cholera in the developing world by improving ways to track its spread and researching inexpensive methods for filtrating out the infection agents of cholera in water systems. Some of these tracking methods include observing weather patterns, surface water temperatures,

concentrations, and rainfall patterns. Colwell's findings of
correlations between these phenomena showed that the infection rate of cholera is connected to water temperatures. This rising temperature causes
algae blooms that host cholera bacteria, and rainfall and extreme weather patterns aid in spreading cholera among water systems. Colwell also concluded that

Present-day climate change includes both global warming—the ongoing increase in Global surface temperature, global average temperature—and its wider effects on Earth's climate system. Climate variability and change, Climate change in ...

cloth or nylon mesh filters placed over water pots to acquire safe drinking water from their local waterways. These inexpensive and readily available materials yielded a 48% reduction in cholera, when compared with the control: absence of any type of filter.
