Dengue in Malaysia Essay -- Health, Diseases

Dengue has now emerged as one of the major commonplace health problems in Malaysia. It was first reported in 1901 in Penang and since consequently the disease has become endemic concentrating mostly in urban areas. The objectives of this theatre of operations were to utilize the temporal role-spatial model to determine high risk areas for the dengue fever outbreak. This hear examined a total of 25000 confirmed dengue fever cases, geo-coded by utter in the city of Subang Jaya between Jan 2006 and December 2009, were included in the study. The results were bony from a measurement of the iii temporal risk characteristics (Frequency, duration and intensity) in order to determine the severity and magnitude of outbreak transmission.The set of the three indices were considered high in a spatial unit when their standard set were positive. Measurement of the three temporal risk indices found that there were areas with probatory high value for each of the temporal indices. This sug gested that areas within Subang Jaya Municipality had incompatible temporal characteristics for dengue occurrence. The utilization of three risk measures enabled to identify higher-risk areas for the occurrence of dengue fever, concentrated in the citys northern region. The correlation coefficient for all the three types of relationship was above 0.7. The value indicated that there was a robust correlation between each temporal risk indices. Even though case notification data are subject to bias, this information is easy in the health services and can lead to important conclusions, recommendations and hypotheses. As a recommendation, the temporal risk indices can be utilized by public health officials to characterize dengue rather than relying on the handed-down case incidence data.... ...rrupted cases. This index gives an idea of the persistence of transmission and represents the fairish duration, in weeks, of epizootic waves that occurred in the given period.Intensity inde x (), characterized as the mean incidence of cumulative dengue cases occurring in consecutive weeks per epidemic wave that had persisted for more than two week. It can be expressed as = TI / OEwhere TI is the incidence rate during the given period and OE is exposit above. It assesses the severity of transmission, and is based on sequences of weeks with the occurrence of uninterrupted cases. High values mean time-concentrated transmission.The dengue cases were provided by MPSJ where dengue cases were summarized according to the housing area, on a weekly basis. Therefore, this study used a week as a temporal unit for better comparison on different indices.
