Introduction

Banda Aceh City, located in the province of Aceh, Indonesia, has been identified as an endemic area for dengue hemorrhagic fever (DHF). The city has experienced a significant number of DHF cases over the past decade, with a total of 3,168 cases reported between 2010 and 2019, resulting in 16 deaths. This alarming trend highlights the need for a comprehensive understanding of the spatial distribution of DHF vulnerability in the city. This study aims to analyze the spatial distribution of DHF vulnerability in Banda Aceh City using various parameters, including rainfall, air temperature, humidity, and population density, which are believed to have a close link to the Aedes aegypti mosquito habitat, the primary vector of the DHF virus.

Background

Dengue hemorrhagic fever is a mosquito-borne viral disease that is prevalent in tropical and subtropical regions around the world. The Aedes aegypti mosquito is the primary vector of the disease, and its habitat is closely linked to environmental factors such as rainfall, temperature, and humidity. In Banda Aceh City, the high population density and urbanization have created an ideal environment for the Aedes aegypti mosquito to thrive, leading to a significant number of DHF cases.

Research Parameter

The selection of the right parameters is crucial in understanding the dynamics of DHF distribution in Banda Aceh City. This study used several parameters, including:

Rainfall: Rainfall data showed a positive correlation with DHF cases of 0.25, indicating that increased rainfall has the potential to increase the number of cases.
Air Humidity: Air humidity showed a higher correlation of 0.42, indicating that moist environmental conditions strongly support mosquito habitats.
Temperature: Temperature showed a negative correlation of -0.47, indicating that higher temperatures may not always contribute to an increase in DHF cases.
Population Density: Population density showed a significant positive correlation of 0.71, indicating that areas with a more dense population tend to experience higher DHF cases.

Spatial Analysis Results

The results of spatial analysis showed that high vulnerability to DHF is located in Jaya Baru, Baiturrahman, Syiah Kuala, and Kuta Alam. The vulnerability mapping identified three zones based on DHF's vulnerability level:

High Vulnerability Zone: 3,262 km² or 53.15% of the city's area
Moderate Vulnerability Zone: 2,354 km² or 38.36% of the city's area
Low Vulnerability Zone: 521 km² or 8.49% of the city's area

Conclusion and Implications

This analysis provides a clear picture of the distribution of DHF's vulnerability in the city of Banda Aceh. The findings of this study are crucial for the authorities and the community to take preventive steps, such as increasing mosquito prevention and control programs, as well as increasing public awareness of risks and ways to prevent DHF. By utilizing existing data and analysis, the city of Banda Aceh can be better prepared to deal with and reduce the impact of DHF in the future.

Recommendations

Based on the findings of this study, the following recommendations are made:

Increase Mosquito Prevention and Control Programs: The city should increase its efforts to prevent and control mosquito breeding sites, particularly in areas with high population density.
Public Awareness Campaigns: The city should launch public awareness campaigns to educate the community about the risks and ways to prevent DHF.
Data-Driven Decision Making: The city should utilize data and analysis to inform decision-making and develop targeted interventions to reduce the impact of DHF.

Future Research Directions

This study provides a foundation for future research on the spatial distribution of DHF vulnerability in Banda Aceh City. Future studies should focus on:

Long-Term Monitoring: Long-term monitoring of DHF cases and environmental factors to identify trends and patterns.
Intervention Studies: Intervention studies to evaluate the effectiveness of mosquito prevention and control programs and public awareness campaigns.
Data Integration: Integration of data from multiple sources to develop a comprehensive understanding of the factors that affect DHF vulnerability.

Conclusion

In conclusion, this study provides a comprehensive analysis of the spatial distribution of DHF vulnerability in Banda Aceh City. The findings of this study highlight the need for targeted interventions to reduce the impact of DHF in the city. By utilizing existing data and analysis, the city of Banda Aceh can be better prepared to deal with and reduce the impact of DHF in the future.
