Cholera - the threat is not over

Abstract

Community health Cholera – The Threat Is Not Over A Water Research Commission funded study successfully assessed the source of several disease-causing pathogens, their route through and survival in the environment, thereby forming a basis for the development of appropriate catchment management and intervention strategies to reduce the health risk to water users. The most common source of contamination of surface waters is human and animal wastes. The introduction of waterborne pathogens by these sources is of particular concern, especially since there are still millions of people in South Africa who, out of necessity, make use of these unsafe sources for drinking water and other uses. At present, most of the water industry’s efforts are focused on the removal of waterborne pathogens during water treatment rather than preventing these pathogens from entering the environment.
