Objective: The causes for the increasing number of dengue cases are complex and multifactorial. The approach taken must combine influencing factors, and comprehensive prevention strategy is needed that includes all the components of factors that influence dengue disease to predict the incidence of the disease. This research aimed to analyze the relationship between population and climate components including population density, population density <15 years old, sanitation, temperature, humidity and rainfall, on the incidence rate of Dengue Hemorrhagic Fever (DHF).Material and Methods: This study used a cross-sectional design, with the research sample being all sub-districts in Bengkulu City, Indonesia (67 sub-districts). Data analysis was conducted using structural equation modeling to create a dengue modeling based on population and climate factors, through the SmartPLS application.Results: Population and climate factors had a significant relationship with the incidence rate of dengue, with p-values of 0.018 and 0.000, respectively. Population and climate factors had a percentage effect on the incidence rate of dengue (36.9%).Conclusion: Population and climate factors had an influence of 36.9% on the incidence of dengue. There were many factors affecting the incidence of dengue, so a more comprehensive modeling of the various influencing factors is needed. Dengue modeling is crucial as an early warning system for the early prevention of dengue outbreaks, so that the control strategies implemented can be more effective.

Soil-Transmitted Helminths (STH) is a worm infection with a prevalence of 1.5 billion people worldwide and is mostly found in preschool and school children. Worm infection can affect the level of concentration and the quality of children's learning which results in less optimal achievement within their potential. The purpose of the research was to determine the correlation between STH infection and anemia and the level of concentration in children grades II-VI of elementary school in Kampung Melayu Sub-district, Bengkulu City. The research conducted using an analytic observational with the cross-sectional design. The research took 215 students as samples with a stratified random sampling method. Feces specimens were examined by using Kato-Katz technique. Haemoglobin levels were measured by using the POCT method and students' concentration levels were tested by using the Bourdon Vos Test. The results showed a significant relationship between STH infection with the occurrences of anemia (p = 0.001; RP = 0.225) and very weak correlation strength between STH infection with the concentration level (p = 0.014; RP = -0.167). Worm infection in preschool and school children can cause anemia and nutrition deficiency which affect their growth and development, cognitive function, concentration levels and learning achievement. Continuous education and coordination with related institutions is necessary to carry out strategies for preventing and treating worms thoroughly.

BACKGROUND: One of the factors contributing to dengue’s endemicity is the density of the dengue vector, namely, Aedes aegypti as the primary vector and Aedes albopictus as the secondary vector. Bentiring and Kandang Limun villages are high endemic areas of dengue. AIM: This study aimed to determine the relationship between dengue endemicity and density figure (DF) and Maya index (MI) in Bentiring and Kandang Limun villages, Bengkulu city. METHODS: This study used a cross-sectional design. The sampling technique used proportionate stratified sampling. The sampling refers to the guidelines for dengue entomology surveys according to the WHO 1999 criteria. A total of 400 ovitraps were installed, 200 ovitraps inside the house and 200 ovitraps outside the house. RESULTS: The results showed that Bentiring and Kandang Limun villages had a high risk of dengue transmission based on entomological parameters, namely, ovitrap index (OI) 56% and 55% (DF 6), house index (HI) 45% and 44% (DF 6), container index (CI) 23% and 23% (DF 6), and BI 96% and 120% (DF 7 and 8). The areas have a high risk of dengue transmission based on the MI 71% and 76%, respectively. There is a relationship between dengue endemicity and entomological index in Bentiring and Kandang Limun villages, Bengkulu city, with a significance value (p = 0.000) and a powerful correlation (r = 1.000). CONCLUSION: There is a relationship between dengue endemicity and the MI in Bentiring village and Kandang Limun village, Bengkulu city, with a significance value (p = 0.014 and 0.058) and a powerful correlation (r = 0.920 and r = 1.000), respectively. The entomological index and DF are predictors for dengue prevention and control environment to minimize mosquito breeding sites and reduce disease transmission.

In Bengkulu, as in other areas of Indonesia, dengue is one of the most important vector-borne diseases. The primary strategy to control dengue is by reducing the vector population using insecticides. However, applications of insecticides becomes a contributing factor in the development of vector resistance. As there is no effective dengue drug or safe vaccine available, vector control remains the most effective intervention to reduce incidence and prevent transmission and outbreak. This study aimed to determine the entomological parameters and resistance status to temephos of Aedes aegypti larvae from Lingkar Barat village and Jalan Gedang village (dengue endemic areas). This study used cross-sectional and experimental with post-control only design. The sampling refers to the guidelines for dengue entomology surveys according to WHO 1999 criteria. Aedes aegypti eggs were collected by ovitraps and reared to larvae stage. Susceptibility test of larvae to the temephos was estimated using standard WHO. Mortality of larvae Ae. aegypti after 24 hours with multiple concentration of temephos indicative of highly resistant. Entomological parameters for house index (HI), container index (CI) and container pupa index (CPI) in Jalan Gedang village and Lingkar Barat village were estimated: 7%, 12% for HI and 1.97%, 3.43% for CI, and 5%, 2% for CPI, respectively. The proportion of controllable sites is higher than disposable sites, it has a high risk as breeding places for mosquitoes indicates a high potential risk as breeding place and transmission of dengue. Awareness sanitation in the home and surrounding environment must be possessed by each individual community in order to prevent and overcome the incidence of dengue. These data should be of value in formulating dengue control programs.
