Dengue Fever risk in Asunción

Dengue Fever Prevention Guide for Asunción

Dengue fever is a viral infection transmitted by Aedes aegypti mosquitoes. Symptoms include high fever, severe headache, joint and muscle pain, and rash. In serious cases, it can become life-threatening. Asunción's subtropical climate, seasonal rains, and urban density create favorable conditions for mosquito breeding, making prevention essential.

Local Risk Factors

Asunción's warm temperatures and frequent rainfall from October through April create ideal breeding environments. Standing water accumulates in discarded tires, uncovered water storage containers, flower pots, and construction debris. Neighborhoods with limited waste management infrastructure face higher exposure. The city's dense population allows rapid transmission once cases emerge.

Prevention Steps

Eliminate standing water weekly. Empty, scrub, and cover all containers that collect rainwater, including buckets, plant saucets, and old tires. Mosquitoes breed in as little as a bottle cap of water.

Use insect repellent containing DEET, picaridin, or oil of lemon eucalyptus, especially during early morning and late afternoon when Aedes mosquitoes are most active.

Install or repair window and door screens. Sleep under mosquito nets if screens are unavailable, particularly during peak transmission months.

Wear long sleeves and long pants during dawn and dusk hours. Light-colored clothing offers additional protection.

Report stagnant water in public areas to municipal authorities. Community cleanup efforts significantly reduce breeding sites across neighborhoods.

Seek medical attention immediately if fever, severe headache, or unusual bleeding occurs. Early detection prevents complications.
