Neglected tropical diseases


Dengue fever is an acute febrile disease transmitted by the bite of an Aedes mosquito infected with any one of the four dengue viruses. Dengue fever, with its severe manifestations Dengue Haemorrhagic Fever (DHF) and Dengue Shock Syndrome (DSS), has emerged as a great public health concern, spreading to all tropical and sub tropical countries in the world. An estimated 2.5 billion people in more than 100 countries are at-risk and an estimated 50 million dengue infections occur annually in the world. It is of particular importance in South East Asia, which bear high burden of dengue.

The increasing incidence, severity and frequency of dengue epidemics are linked to trends in human ecology, demography and globalization, and may have been influenced by climate change. However, there is strong commitment from global community to tackle the reversing trend of dengue. The component to achieve effective dengue prevention and control include: diagnosis and case management; integrated surveillance and outbreak preparedness; sustainable vector control with integrated vector management approach; and research.The goal to reduce dengue burden can only be achieved with several enabling factors for implementation, including advocacy and resource mobilization; partnership, coordination and collaboration; optimal community participation through communication strategy for behavioral outcomes; capacity building and adequate monitoring and evaluation.
