Surveillance for Diarrheal Diseases

All health facilities that serve the refugee population should maintain case records of diarrheal diseases as part of the routine HIS. Records should include the degree of dehydration at the time of presentation. Case definitions should be standardized. Dysentery cases should be recorded as a separate category.

Any increase in the number or severity of cases, change in the type of diarrhea, rise in diarrhea-specific mortality, or change in the demographic breakdown of the cases should be reported. A case definition for cholera should be established for the purpose of surveillance. Any suspected cholera cases should be reported immediately.

Sample case definitions for cholera and dysentery are provided below.
