Spatial density of dengue incidence: A case study of a dengue outbreak in Seksyen 7, Shah Alam

Abstract

Dengue is a major vector-borne disease caused by any one of four closely related dengue viruses. The viruses are transmitted to humans by the bite of an infected mosquito (Aedes aegypti or Aedes albopictus). The study was conducted in the Seksyen 7, Shah Alam where there is a marked increase of dengue cases evidenced during the last few years. This study aimed to establish spatial density of dengue incidence in Seksyen 7, Shah Alam using Geographical Information System (GIS) and spatial statistical tools. Methodology: We analysed 23 ovitrap index and 2389 dengue cases from 2013 to 2014. Data were collected from Petaling District Health Office and Shah Alam City Council. Spatial statistical tools were used to show spatial correlation of dengue cases and kernel density was implemented to identify dengue hotspot localities. Results: The result showed that dengue cases were spatially random (p
