Abstract for: Cholera response model: Yemen Al-Hudaydah

As of November 2020, the World Health Organization reported 2.5 million suspected cholera cases and nearly 4,000 deaths in Yemen. In Yemen, humanitarian response is particularly needed when epidemics occur during or as a consequence of conflict and political upheaval. This study aims to quantify and evaluate the lessons learned from the 2017 and 2018 cholera responses. The model extended the classic infection structure with empirically-grounded operational structures: oral rehydration corner, diarrhea treatment center, water and sanitation intervention, vaccination, and data surveillance system. The data collected are epidemiological data: and cholera response (interventions) data. The model demonstrates that individual and joint-interventions can have varying degrees of effectiveness depending on the supply, demand, and progression of the epidemic (timing). Deconstructing the interventions from BASE (historical behavior) to Business as Usual (BAU) has shown significant impacts from the humanitarian cholera response in 2017. A 55% more deaths if nothing has been done in Al-Hudaydah. On the other hand, a 30% of death can be prevented if interventions, especially vaccination, can be initiated earlier. A user-friendly interface was created to facilitate policy testing and engage multi-sector stakeholders in more effective communication during the cholera response planning.
