Dengue Fever risk in Vitória

Dengue Fever Prevention Guide for Vitória, Brazil Risk Score: 67/100 — Moderate to High Risk Dengue fever is a viral infection transmitted primarily by the Aedes aegypti mosquito. Symptoms include high fever, severe headache, joint and muscle pain, rash, and in serious cases, hemorrhagic complications. There is no specific antiviral treatment, making prevention essential. Why Vitória faces elevated risk: the city's tropical climate with warm temperatures year-round creates ideal breeding conditions for mosquitoes. Frequent rainfall accumulates in urban areas, and the combination of dense population, construction sites with standing water, and port activity contribute to persistent mosquito populations. The coastal humidity and average temperatures between 23-30°C accelerate mosquito breeding cycles. YOUR ACTION PLAN 1. Eliminate standing water weekly. Check plant saucers, tires, buckets, gutters, and water tanks around your home. The Aedes mosquito breeds in clean, stagnant water, and eggs survive months without water. Scrub containers to remove eggs attached to surfaces. 2. Use repellent daily. Apply DEET or icaridin-based repellent during dawn and dusk when Aedes is most active. Reapply every 4-6 hours, especially after rain or sweating. 3. Install window screens and use mosquito nets. Ensure all windows have intact screens. Sleep under insecticide-treated nets if screens are unavailable, particularly for children and elderly family members. 4. Wear long sleeves and pants during peak hours. Light-colored, loose-fitting clothing reduces bite exposure significantly. 5. Report breeding sites to municipal health services. Call the local Vigilância Epidemiológica to report abandoned properties, flooded areas, or construction sites with standing water. Community action reduces city-wide risk. Additional tip: during heavy rain seasons (October-March), increase vigilance and check your property twice weekly.
