Dengue fever threatens more than 200 million people in Indonesia. The disease has spread to over 400 of Indonesia's 497 districts, 26 of which have been declared hyper-endemic. These districts are all situated in West Java, the most densely populated province in the country. A study was conducted to detect clusters of dengue incidence during 2007-2013 in Cimahi City, which is situated in the Bandung metropolitan area in West Java. A temporal-spatial analysis based on population data from the local Bureau of Statistics, and monthly analysis of dengue incidence from the local Municipality Health Office, were performed using SaTScan™. This retrospective space-time analysis with a Poisson distribution model and monthly precision revealed 24 significant clusters (P<0.001) throughout the seven-year study period. The most likely cluster was detected in the centre of Cimahi City and followed as it moved to the northern part of the city. Several primary and secondary clusters were identified in villages surrounding Cimahi City over time, and our conclusion is that we identified a dynamic spread of dengue fever initiated from the city centre to surrounding areas during the study period. In general, clusters were more common in the first quarter of each year. An in-depth investigation to understand relevant risk factors in high-risk areas in Cimahi city is encouraged.

Although at present the number of malaria cases in Pangandaran is low, a time will increase again because malaria is a re-emerging disease. To determine the potential of reemergence of malaria, have done the research by identifying the pattern of disease, the malaria parasite, knowledge, attitudes and behavior as well as the mobilization of the population, and environmental factors and entomology malaria. The collected data were analyzed to determine the potential reemergence of malaria using dynamic analysis system. Identification of the parasitological are showed that all of the blood sample results were all negative Plasmodium spp  The results of interviews showed that the state of knowledge in the category malaria mostly not good (64.58%), 28.23% of respondents have a regular ART wander, 11.53% of them never came home ill with malaria. While the environmental status of settlement of respondents relation to malaria transmission mostly (67.99%) is not good. Survey entomologist discovered 1,037 mosquitoes which consists of 8 species of Anopheles spp. Most are An. vagus (67.89%) while the least is An. indefinitus. Based on the methods of arrest, most in catching a rest at home (98.46%) and least is the catch UOD (0.10%). The analysis data had been resulted that highest leverage effect on the reemergence of malaria is the mobilization of the population. So that be advised to monitoring the population migrating to and from endemic areas, especially outside Java through migration survey.
