Color-enhanced transmission electron micrograph of Vibrio cholerae, one of multiple pathogenic vibrios whose ecology is closely tied to changes in temperature. © James Cavallini/Science Source

The cholera epidemic that ravaged Haiti after its January 2010 earthquake resulted from a confluence of environmental factors, including unusually heavy rains following an intensely hot summer. © Reuters/Carlos Barria
None
It’s been suggested that the island nation’s limestone foundation may have contributed to the cholera epidemic by increasing the alkalinity of Haiti’s rivers, achieving a pH more favorable for V. cholerae growth. © John B. Crane
None
The devastation of drinking water and sanitation systems set the stage for widespread exposure to the pathogenic vibrio. © Reuters/Carlos Barria
None
With its low salinity and rising water temperatures, the Baltic Sea is becoming prime habitat for Vibrio species. During the exceptionally hot summer of 2006, at least 66 people developed vibrio infections after visiting Baltic beaches. © Kacper Kowalski/Panos Pictures
None
Planktonic organisms called copepods are the natural hosts for vibrios. The inset shows V. cholerae dividing on the surface of a copepod egg sac (arrows). A single copepod may carry 10,000 vibrios. Copepod: © Albert Lleal/Minden Pictures/Corbis; V. cholerae: Huq et al. (1983)

Filtering water through several layers of sari cloth is an easy way to reduce exposure to V. cholerae. The layered fabric makes a fine enough mesh to capture copepods—and the vibrios attached to them. © G.M.B. Akash/Panos Pictures

A pilot Vibrio Risk Map on the E3 Geoportal website identifies areas where environmental conditions may be conducive to vibrio growth. The model is updated daily with remotely sensed data on variables such as sea surface temperature and salinity. © European Environment and Epidemiology Network
