Mohammed Ahamed Hajjam
Abstract
Arboviral infections have emerged as a significant public health challenge worldwide, particularly in tropical and subtropical regions where environmental conditions support the establishment and expansion of competent mosquito vectors (1). Among the most important mosquito-borne arboviruses affecting human populations are dengue virus (DENV), chikungunya virus (CHIKV), and West Nile virus (WNV), which continue to cause substantial morbidity due to their expanding geographic distribution, recurrent outbreaks, and potential for co-circulation in endemic regions.
