Epidemiology of Dengue in Malaysia


In Malaysia, dengue is predominantly an urban disease due to the abundance of the principle vector Aedes aegypti which is at a close proximity to high densities of susceptible hosts. The states of Selangor, Wilayah Persekutuan Kuala Lumpur and Johor are the areas that have been largely affected by the disease and are reporting high numbers of cases.

Factors like population growth in urban areas, the indiscriminate disposal of waste coupled with the lack of efficient solid waste management and the increased and efficient movement of dengue viruses in infected humans through modern transportation have all contributed to the marked increase in the occurrence of dengue.


After reporting 120 836 dengue fever cases in 2015 , the highest number of cases reported, Malaysia appears to be continuing that trend with summer upon us and the health ministry has reported nearly 50,000 cases through the first five months on 2016.
