Dengue hemorrhagic fever prediction in coastal area using geographically weighted regression

Dengue hemorrhagic fever (DHF) is still a health problem globally, including in Indonesia. Geographical and climatic conditions in coastal areas are different from other areas, which may impact differences in environmental risk factors for dengue. This study aims to create a prediction model for the incidence of DHF in coastal areas. The research was conducted in Bantul Regency, Indonesia, involving data from 2015-2019. Dengue incidence data were collected from the health office. Climatic data were from climatology station. Data on altitude and shoreline distance were obtained by geographic information system (GIS) processing. Population density and wide settlement area are obtained from the Bureau of Statistics. The geographically weighted regression (GWR) analysis was carried out using GWR4. The results showed that GWR with a weighting of Fixed Bi-Square Kernel obtained an R2 value of 0.7768, better than the global model (R2 0.5254). It indicates that DHF (Y) in Bantul Regency is 77.68% determined by population density (X1), altitude (X2), settlement area (X3), shoreline distance (X4) and rainfall (X5) and the remaining 22.32% are influenced by other variables which are not investigated. Geographically, the predictor variables explain the DHF incidence with a strong category in the central region, and weak in coastal area.

Overview of Dengue Fever (DHF) incidence based on population density in Indonesia

Dengue fever (DHF) is an infectious disease caused by the dengue virus, with Aedes aegypti and Aedes albopictus mosquitoes as vectors. The prevalence of DHF globally has increased significantly, and the infection has become endemic in many regions including Indonesia. The purpose of this study was to determine the relationship between population density and the incidence of Dengue Hemorrhagic Fever (DHF) in Indonesia. This research uses a descriptive method with a population correlation study. Descriptive analysis in this study utilized the Health Mapper version 4.3.0.0 application while the population correlation test used the SPSS data processing application with the Spearman bivariate test. The population in this study is provinces in Indonesia. The independent variable in this study is population density in provinces in Indonesia, while the dependent variable in this study is the incidence of Dengue Fever (DHF) in Indonesia in 2020, 2021, and 2022. The results showed that DHF cases are directly proportional to the high population density in a province. The correlation test on dengue cases and Indonesia's population density in 2020 showed a correlation coefficient of 0.811. The correlation test between DHF cases and Indonesia's population density in 2021 showed a correlation coefficient of 0.766. The correlation test between dengue cases and Indonesia's population density in 2022 showed a correlation coefficient of 0.741.

Safety and Proven Risk Assessment on the Release of Wolbachia-Inserted Aedes Aegypti: Lesson Learned from the Partial Resistance of the Community

Aims: to describe the basis of partial rejection from the community regarding the government's plan to expand the range of releases of Aedes aegypti mosquitoes which have been inserted with the endosymbiont bacteria Wolbachia spp. to reduce the incidence of dengue hemorrhagic fever and offers a more rational approach based on community based medicine to educate massively first before expecting community participation.
 Discussion: Aedes aegypti which laboratorily inserted with Wolbachia, an endosymbiont bacterium, naturally occurring in insects is actually a great success story in several countries, e.g., Brazil. In Jogjakarta, Indonesia this success story also repeated even though unfortunately when the government tries to expand the programme, some part of the community reject it. Lack of sufficient community education perhaps become the main reason of rejection from those who do not understand yet regarding the benefit.
 Conclusion: Tackling social determinants of Health is necessary in order to make a national programme can be implemented and receive support from the community.

Assessing Dengue Hemorrhagic Fever Risk: Insights from Behavioral Aspects and Home Environmental Conditions

As the provincial capital, Jambi City has witnessed rapid development, evident in the construction of 5,000 housing units between 2019 and 2021 amid the COVID-19 pandemic. However, if left unoccupied, these settlements could potentially become breeding grounds for mosquito larvae, particularly Aedes aegypti, contributing to the escalating dengue cases in the city. This study aims to analyze the risk factors for dengue hemorrhagic fever based on behavioral aspects and environmental conditions. Conducted in the Pinang Merah Alam Barajo Urban Village of Jambi City, this observational analytic study involved 108 randomly selected respondents. The research data underwent analysis using the chi-square test, with statistical significance set at ≤ 0.05. The findings revealed that most community behaviors fell into the 'good' category, including habits like hanging clothes, collecting rainwater around the house, using abate powder in water reservoirs, weekly drainage of water reservoirs, proper disposal of used items, monitoring of larvae through cards, and keeping larvae-eating fish. The incidence of dengue hemorrhagic fever was significantly associated with hanging clothes indoors (p=0.000), collecting rainwater around the house (p=0.004), and draining water reservoirs once a week (p=0.004). However, no significant associations were found with the use of abate powder (p=0.380), disposing of used goods (p=0.087), monitoring larvae with cards (p=0.134), and keeping fish (p=0.122). In conclusion, the study highlights a strong correlation between dengue hemorrhagic fever and certain behaviors, notably hanging clothes indoors, collecting rainwater around the house, and draining water reservoirs on a weekly basis.
