The city of Guarujá, located on the coast of São Paulo, has achieved a significant milestone by reducing dengue cases by 85% in the first two months of 2026 compared to the same period in prior years. The municipal government reported that this year, only 60 cases of dengue were confirmed, a drastic drop from 417 cases reported in early 2025 and a staggering 1,671 incidences in 2024. This improvement reflects the effectiveness of ongoing preventive measures and community health efforts.

Key initiatives contributing to this reduction include regular inspections by health agents, which are conducted every Monday, and the strategic use of biological controls such as fish in standing water to deter mosquito breeding. The local government's proactive stance in engaging with the community and monitoring residential areas has played a crucial role in the overall prevention strategy against dengue fever, a mosquito-borne viral infection that poses serious health risks.

Municipal health authorities credit the sharp decline in dengue cases to the diligent work of the Endemic Control and Combat team from the Secretary of Health. Ongoing education and awareness campaigns in the community have further supported these health initiatives, underscoring the importance of continuous monitoring and preventive health measures to maintain public health and minimize the risk of outbreaks in the future.
