History of Dengue in Malaysia
In November 15, 1902,Skae reported the first known published account of an outbreak of dengue in Malaya. He described a dengue outbreak in the northern state of Penang from December 1901 to March 1903. Severe dengue (Dengue Haemorrhagic Fever) was first observed in Malaya in the city of Georgetown, Penang in November 1962.
From the 1960s dengue cases began to spread into the urban areas of Penang and Kuala Lumpur. By the early 1970s, DHF had spread to the whole Malaysia and has since caused a significant health burden to the population in Malaysia.
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.
From Jan. 1 through May 31, Malaysia has seen 49,830 dengue fever cases, with greater than half reported from Selangor State (26,704). Johor state has seen 6800 cases followed by Kuala Lumpur with 3400. Through mid-May, 109 dengue related fatalities have been reported.
