As part of the objective for strengthening existing surveillance system and improving the speed and efficiency of data collection, analysis and public health response, the Electronic Disease Early Warning System (eDEWS) was implemented by the World Health Organization (WHO) in collaboration with the Ministry of Public Health & Population (MoPHP) to strengthen the national disease surveillance capacity and capabilities, which remains weak in Yemen. The eDEWS is an initiative to use the mobile software and electronic means for more efficient transmission of surveillance data, automated analysis and information sharing and development of, integrated, and interoperable surveillance systems at federal, governorate and district levels. The overall goal of eDEWS is to minimize morbidity and mortality due to communicable diseases through detection of potential outbreaks at their earliest possible stage and to facilitate timely interventions.
