Impact of climate and landuse variability based on dengue epidemic outbreak in Subang Jaya

Dengue disease has continually been a major public health problem in Malaysia. The numbers of cases have risen yearly and it had become more serious in the early of 21
^st
century. Therefore, effort to reduce the number incidences must be taken seriously and should be supported from various agencies. Concerted effort from various agencies is vital effectively manage the dengue problem. Despite all of the effort taken by the Ministry of Health in fighting dengue in Malaysia, the numbers of cases have risen yearly and it had become more serious in the early 21
^st
century. Subang Jaya was chosen due to its highly reported dengue cases year by year. Meteorological data and landuse pattern being consolidated using GIS software and its components as an analytical tool. As a results, weather variables including relative humidity, temperature and precipitation have significant correlation with confirmed dengue cases distribution; Rainfall (t = 0.750**), (t−1=0.649**), (t−2=0.430**). For temperature (t = −0.405**), (t−1= −0.414**), (t−2= − 0.485**). As for relative humidity, the correlation is not continuously significant throughout the year 2006 until 2010 but still have good correlation weightage in 2006 for (t−1 = 0.662**). In line with that, hotspot identification of dengue cases map was fabricated by clustering pattern analysis. So, it will benefit the decision makers as well as the planning actors in just not to concentrating on the current conventional method in controlling dengue occurrence but also to better understand other contributing factors which statistically proved to have correlation with the dengue cases distribution number in Subang Jaya.
