  • Among the 305 affected districts, 23 districts did not report any case the last three consecutive 3 weeks.

Governorate and District level

  • The trend at country level over the past 3 weeks is considered stable.

  • At governorate level, the trend from W38-W40 increased in Saada governorate (+12%).

  • No governorate is reporting a CFR higher than 1%.


  • WHO is strengthening the data collection and reporting.

  • The following recommendations are still very important and must be applied in all DTCs and ORCs:
    ALL line listed cases 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.

  • the cholera line list register should not be used for the recording of all visits to DTC and ORC: one register to record consultations at DTC and ORC and one line list register only for those that meet case definition of suspected cholera must be put in place.
