2) Sero-prevalence of dengue among suspected cases reported to EDEWS in Yemen in 2024

Abstract

Background: Dengue is an endemic vector borne diseases in Yemen. Clinically, the disease is similar to the other mosquito transmitted disease like malaria, Chikungunya and west Nile virus.

Objective: to determine the sero-prevalence of Dengue virus among suspected patients in the southern and eastern governorates of Yemen during the year 2024.

Methods: it is a cross-sectional descriptive study that. Data used for this study were sourced from the Electronic Integrated Disease Early Warning System (EIDEWS), an extended surveillance platform that tracks epidemic-prone diseases in real time.

Results: A total of 8609 suspected dengue cases were reported in the year 2024 to the electronic early warning system in the southern and eastern governorates in Yemen during the year 2024. A total of 221 out (20.2%) of 1091 suspected cases of dengue were positive for IgM specific for dengue while 393 out of 831 clinically diagnosed dengue cases were positive for IgG specific for dengue (48.9%) given the dengue IgG: IgM ratio to 2.4. The highest sero-prevalence was observed in the age group 15-44 years (22.44%). Shabwah, Marib and Aden governorates has the highest prevalence of dengue. Coinfection was existing in dengue confirmed cases with Chikungunya (17.6%), west Nile virus (2.3%) and malaria (0.9%).

Conclusion: High endemicity of dengue were identified among patients with dengue like illness. Coinfection was existing in dengue confirmed cases with Chikungunya.
