<p>A Field/full-scale cholera outbreak SimEx was conducted between 20-24th June 2023, in SWD. We used WHO SimEx Manual as guide. We developed a checklist to assess components of emergency preparedness and coordination. Four(4) health facilities(HFs) were selected. We coached 11 ‘mystery clients’(MCs) on signs and symptoms of cholera and made them to report at selected facilities. They reported with various degrees of diarrhoea(5-8x) and vomiting(2-3x) over a period of two(2) days at different times, and reported back to SimEx instructors, their experiences. From day 3-4, SimEx team visited the various HFs and the SWD health directorate. We interviewed clinical, surveillance and public health(SPH) teams, reviewed folders of MCs for case management and assessed coordination and IPC practices</p>
