Guidelines for cholera control.
This manual was designed to help national health workers, particularly managers of diarrheal disease control programs, to implement cholera control activities within the context of national programs. Recent knowledge of the bacteriology and epidemiology of cholera is presented, followed by a discussion of necessary preparations for cholera control. Case fatality rates of as high as 50% have been reported in unprepared communities, but the rate diminishes to under 3% when proper treatment becomes available. Preparations for cholera control including formation of national epidemic control committee, surveillance activities, health education activities, training in clinical management of acute diarrhea, laboratory services, establishment of mobile control teams, and logistics are described. The epidemic phase of a cholera outbreak requires intensification of ongoing diarrheal disease control activities. Components of the epidemic phase program including early case finding, establishing treatment centers, treatment, epidemiological investigation, laboratory support, control and prevention are discussed. Basic supplies for a mobile control team are listed.
