The cumulative total of cases is 6587, including 45 associated deaths (case-fatality rate 0.7%), since the beginning of the current outbreak in December 2017 along the Shabelle River.

WHO is providing leadership and support to the Ministry of Health response efforts to this continued outbreak. WHO has continued to support clinical care delivery, including supervision and monitoring of case management in cholera treatment centers. Surveillance and prompt rumour investigation have been ongoing. All alerts have been responded to across the country through the early warning alert and response network (EWARN), and routine collection and analysis of stool samples have continued at the NPHL. An oral cholera vaccination (OCV) campaign has been planned for February 2019, targeting 660 000 people living in internal displaced person (IDP) camps in six high-risk districts in Lower Jubba, Middle Shabelle, Lower Shabelle, and Banadir regions. Also, an expansion of reporting sites through the EWARN system has been planned, adding another 400 health facilities in the country.
