Dengue has been reported in Indonesia since1968; the cases tend to increase and spread every year. From 2015-2019 almost all districts in Indonesia had dengue cases. This study aimed to determine the value of the entomological index and its relationship with the treatment of various types of containers and spatial epidemiology. A larval survey was conducted to determine the presence of larvae in water containers. Logistic regression and spatial data analysis were performed to see the distribution and make a buffer area map of Aedes sp. spreading risk. The types of containers observed in this study were water tubs, drums, buckets, refrigerator containers, dispenser containers, and other categories. There were 221 containers found containing Aedes sp. larvae. Container types affected the presence of larvae with adjusted ORs of 2.779 (95% CI: 1.441-5.360) on buckets, 9.812 (95% CI: 1.249-77.051) on refrigerator holders, and 0.301 (95% CI: 0.147-0.617) on dispenser holders, while the other variables were constant. The spatial analysis found that many houses are at risk of dengue transmission within a radius of 100 m. The discovery of containers as potential breeding sites for Aedes sp. provides a chance for an increase in dengue cases in Samarinda.

The number of dengue hemorrhagic fever (DHF) cases endemic at the village Sei Kera Hilir I Sub-district Medan Perjuangan Medan City since 2017 which was 46 cases. One cause of the spread of dengue fever was a place of water container around the house that became the breeding ground for Aedes aegypti. This study aimed to know the relationship of presence of larva Aedes aegypti at water container with DHF incidence in the village Sei Kera Hilir 1 Sub-district Medan Perjuangan Medan City. This research was an analytic observational study with cross sectional design. The samples of this study were 100 homes taken by cluster sampling. The data was analyzed using Fisher’s Exact Test. The most commonly used water container was the bucket (56%), the most common water container with Aedes aegypti was the dispenser (16%), and there were 10 respondents with a history of DHF in the last 1 year. In bivariate analyses, the presence of larvae Aedes aegypti in water container significantly related ...
Dengue fever (DF), one of the most important emerging arboviral diseases, is transmitted through the bite of container breeding mosquitoes Aedes aegypti and Aedes albopictus. A household entomological survey was conducted in Dhaka from August through October 2000 to inspect water-holding containers in indoor, outdoor, and rooftop locations for Aedes larvae. The objective of this study was to determine mosquito productivity of each container type and to identify some risk factors of households infested with Aedes larvae. Of 9,222 households inspected, 1,306 (14.2%) were positive for Aedes larvae. Of 38,777 wet containers examined, 2,272 (5.8%) were infested with Aedes larvae. Containers used to hold water, such as earthen jars, tanks, and drums were the most common containers for larval breeding. Tires in outdoor and rooftop locations of the households were also important for larval breeding. Although present in abundance, buckets were of less importance. Factors such as independent household, presence of a water storage system in the house, and fully/partly shaded outdoors were found to be significantly associated with household infestation of Aedes larvae. Identification and subsequent elimination of the most productive containers in a given area may potentially reduce mosquito density to below a level at which dengue transmission may be halted.

The objectives were to survey Aedes aegypti larval breeding habitats and analyze dengue vector indices. This larval vector survey was conducted in Dongklang village in Ubon Ratchathani province over two years in 2012 and 2013. During each year, dengue vector indices, House Index (HI), Container Index (CI), and Breteau Index (BI), were collected for two periods, dry season (January-April) and wet season (May-August). The number of households infested with larvae in the different years and periods were compared using chi-square test. The results showed in 2012, HI, CI, and BI were 52.7%, 19.9%, and 135.1% respectively in the dry season. In the wet season, the indices decreased. In 2013, dengue vector indices again tended to decrease from dry seasonal to wet seasonal periods. The numbers of households that were infested by Aedes larvae did not differ between years and seasons. Dengue vector indices are alternative methods to predict Aedes mosquito distribution and can be used in the m...

Dengue Hemorrhagic Fever (DHF) is an infectious disease that can be fatal. There were 117 DHF cases in Ogan Ilir Regency in 2018. The presence of Aedes aegypti and community behavior in mosquito breeding eradication are critical for dengue vector larvae survival. The purpose of this research is to establish a link between the presence of Aedes aegypti larvae and the presence of DHF in Beti Village, South Indralaya District, Ogan Ilir Regency, South Sumatra Province. This was an observational cross-sectional study with 49 randomly selected resident houses. The presence of larvae in water reservoirs was used to collect data, whereas the incidence of DHF was obtained through questionnaire interviews with respondents. For statistical analysis, the chi-square test was used. According to the findings of the study, 38.8 percent of respondents have a history of DHF. The majority of the larvae were discovered in water reservoir buckets. There is a link between the type of Aedes aegypti breed...

Dengue is currently one of the most important arboviral diseases, with 2.5 billion people living in areas of risk and many millions of cases occurring each year. A prospective study was carried out in survey of container breeding mosquito larvae and identifying the dengue vector (Aedes species) distributed throughout Tiruchirappalli district, Tamilnadu, India. Aedes mosquito larvae were collected randomly during September 2012 to March 2013 from different natural and artificial containers and the water container index (CI) was calculated. Totally 118 water containers were inspected, among which 38 containers were recorded as positive for dengue vector. The collected larvae were raised to adults for identification. The dengue vector survey reveals the presence of two dominant mosquito species namely Aedes aegypti (45%) and Aedes vittatus (45%). Our study concludes that the Aedes aegypti and Aedes vittatus was most predominant container breeding mosquito in Tiruchirappalli district. T...

Dengue Hemorrhagic Fever (DHF) is caused by Dengue Virus and transmitted by female Aedes mosquito which spread almost all over the world. Aedes sp. mosquito lives cosmopolitan and breeds in wet environments. Panggungharjo and Bangunharjo villages were categorized as endemic and non-endemic DHF areas, respectively. The aims of this research were to study the characteristics of Aedes sp. mosquito breeding sites, the identity of presence species found in the sites, and the resistance status of Aedes sp. mosquitoes against organophosphate insecticide. The method was using a larval survey which consists of 200 houses as respondents located in Panggungharjo and Bangunharjo villages. The larval resistance was tested by a biochemical method since resistance could be associated with esterase enzyme activity. The characteristics of mosquito breeding sites that found were open containers, filled with clear and calm water, dark and rough wall surfaces, the bottom surface was not directly in con...

Objective: A study was conducted in Salto (Uruguay), a city recently invaded by Aedes aegypti (Diptera, Culicidae), in order to identify mosquito-producing containers, the relationship between different Aedes aegypti population indices and environmental risk conditions for the dengue vector. Due to uruguayan climatic characteristics, the vector population decreases abruptly during the winter and regrows when temperature rises, resulting in a particular population dynamic that differs from that of tropical regions. Methods: 20 clusters randomly selected (100 household each) were visited twice and water filled containers and immature mosquitoes were quantified. Pupae per person (PPI), pupae per hectare (PPH) and Stegomyia indices were calculated. The number of mosquitoes in each container type was analyzed, and their spatial location was described. Results: The study was able to detect important epidemiological containers (containers not in use and tanks). While PPI, PPH and Stegomyia indices for the different clusters were correlated, the Stegomyia indices increased significantly between the first and second sampling. Clusters with abundant vegetation, or located on lower ground showed the highest PPI values. Conclusion: Due to its proximity to areas where dengue fever is endemic, Salto becomes valuable for case studies relevant to other areas in the world that could be invaded by this vector.
