|Guidelines for Cholera Control (WHO - OMS, 1993, 68 p.)|
As an outbreak of cholera subsides, emphasis should shift from emergency control measures to preparedness for future outbreaks and long-term efforts to improve the safety of public water supplies and sanitation facilities.
Public health education programmes must continually stress the principles of good personal hygiene, and the importance of using only safe water, of the safe disposal of excreta, and of safe food practices.
Ideally, a water supply system in urban areas should provide potable water under constant positive pressure through a system piped into private homes. The water should be treated with an effective chemical such as chlorine. Properly operated facilities for disposing of excreta in all households are a goal towards which all local authorities should strive.
In rural areas, water sources should be protected from surface contamination, and latrines should always be situated so as to drain away from water sources and catchment areas. The installation of simple devices such as tube wells should be encouraged.
Cholera will ultimately be brought under control only when water supplies, sanitation, personal hygiene, and food handling practices are safe enough to prevent the transmission of Vibrio cholerae O1.
