Abstract:
Dengue fever is a widespread vector-borne disease with significant economic impacts, particularly in endemic regions. This study examines the costs and effects of individual protective behaviors aimed at reducing mosquito bites and preventing dengue transmission. An epidemiological model is developed, incorporating human and mosquito populations to simulate the dynamics of dengue transmission. The model focuses on personal protection measures, including the use of insect repellent, treated clothing, and treated bed nets. The study evaluates the associated household costs of these self-protection strategies and their effectiveness in controlling the disease. Results show that personal protective measures can reduce the number of infected individuals and shorten the duration of outbreaks. However, the costs of these measures can place a financial strain on households, influencing the adoption of protective behaviors and potentially affecting the disease`s progression.
