Abstract

Background and Objective: Aedes aegypti is a significant vector for the transmission of several dangerous arboviral diseases, including dengue fever, Zika, chikungunya, and yellow fever. The present study aimed to investigate the impact of environmental management and integrated methods on the control and reduction of Aedes aegypti mosquito abundance in Chabahar City in 2024. Materials and Methods: To conduct this field study, a comprehensive environmental improvement program—based on Ministry of Health guidelines—was developed for Chabahar City to enhance integrated management measures for combating Aedes aegypti. This was accomplished by having environmental health, community health, and entomology experts complete relevant checklists during urban block surveys.To conduct this field study, a comprehensive environmental improvement program-based on the guidelines of the Ministry of Health-was developed for Chabahar City to enhance integrated environmental management measures for combating Aedes aegypti. This was accomplished by having environmental health, community health, and entomology experts complete relevant checklists during urban block surveys. Results: The results of this study demonstrated that, following environmental improvement operations and chemical control measures in Chabahar City—and coinciding with the beginning of the cold season at the end of 1403 (2024)—the number of probable dengue fever cases declined sharply. Cases fell from a peak of 389 in November 2024 to only 8 by March 2025. This decline indicates the effectiveness of the implemented Aedes aegypti control strategies, potentially in conjunction with seasonal temperature changes. Conclusion: Given the high prevalence of certain arboviral diseases transmitted by Aedes aegypti in neighboring countries and the continuous movement of residents in these regions, it is critical to plan and implement an immediate vector surveillance and control program to prevent the permanent establishment of this invasive mosquito species.
