| Summary: | INTRODUCTION: The frequency and magnitude of
epidemic disease continued to increase in tandem with
rapid urbanisation. Mosquitoes carrying the dengue virus
can increase following unplanned and unhealthy
urbanisation. In the large urban regions, crowded human
populations live in intimate association with equally large
mosquito populations provides the ideal home for
maintenance of the viruses and the periodic generation of
epidemic strains. METHODS: Data from e-Dengue
registry including the urban sub-districts, between 2014 to
2018 were reviewed. Descriptive analysis was conducted
to examine the epidemiology of Dengue fever in the urban
regions of Hulu Langat district, Selangor which consist of
Kajang, Cheras and Ampang sub-districts. RESULTS:
Total incidence rate of Dengue in urban sub-districts in
year 2014 was 1,060 per 100,000 populations (n=10,254)
while in year 2018 the incidence decreased to 691 per
100,000 populations (n=6,762). Most of the cases were
contributed by sub-district Kajang (43%) and Ampang
(23%). Meanwhile the cases were mostly recorded from
premises of landed houses (61%) and strata (21.1%).
Case-fatality rate was increasing in trend from year 2014
to 2017 (0.18% to 0.22%) however noted to decrease in
2018 with 0.15%. Most of the death were from Kajang
sub-district (37%), followed by Ampang (36%).
DISCUSSION: Dense population in urban regions
contributed to Dengue hyperendemicity in Hulu Langat.
Orchestrated holistic approach in controlling Dengue
outbreak in urban regions must be conducted wisely. |
