Dengue Fever risk in Surabaya

Dengue Fever Prevention Guide for Surabaya - Risk Score: 70/100

Dengue fever is a viral disease transmitted through the bite of infected Aedes aegypti mosquitoes. Symptoms include high fever, severe headache, joint and muscle pain, and rash. Severe cases can lead to dengue hemorrhagic fever, which is life-threatening.

Surabaya faces elevated dengue risk due to several local factors. The city's tropical climate with frequent rain creates abundant breeding sites in stagnant water. Dense urban neighborhoods in areas like Tambaksari, Simokerto, and Gubeng provide ideal mosquito habitats. Poor drainage systems and open water storage containers in many residential areas compound the problem. The city's high population density increases human-mosquito contact rates significantly. Seasonal peaks typically occur between March and May following the rainy season.

Five Actionable Prevention Steps

1. Eliminate breeding sites weekly. Empty, clean, or cover all water containers, flower pots, tires, and any items collecting rainwater around your home. This single step reduces local mosquito populations dramatically.

2. Use mosquito repellent daily. Apply DEET, picaridin, or oil of lemon eucalyptus on exposed skin, especially during early morning and late afternoon when Aedes mosquitoes are most active.

3. Install window and door screens. Repair any tears immediately. Consider using bed nets if sleeping areas are not fully enclosed.

4. Wear protective clothing. Long sleeves and pants reduce exposed skin surface, particularly during peak biting hours.

5. Report clusters to local health authorities. Contact the Surabaya Health Department if multiple dengue cases appear in your neighborhood so fogging and community cleanup can begin promptly.

Surabaya residents should remain vigilant year-round, but intensify prevention efforts before and during the rainy season. Early recognition of symptoms and prompt medical care save lives.
