Conclusions and actions

  • In response to the continued increases in numbers of suspected cholera cases, WHO and health authorities are still strongly recommend the following:
  1. Strictly apply case definition. All cases that are line listed MUST meet the case definition of suspected cholera. There must be the presence of acute watery diarrhoea, defined as 3 or more loose stools in the past 24 hours.
  2. Strengthen laboratory testing. At a minimum, 1 in 10 patients should be tested with rapid diagnostic test (RDT). Where feasible, exhaustive testing of all admissions to DTC is recommended. All RDT positive cases should be tested for culture.
  3. Strengthen data collection and reporting. Partners should use one register to record consultations at DTC and ORC, and use the line list register ONLY for those that meet case definition of suspected cholera
