Dengue Fever risk in Cali

Dengue Fever Prevention Guide for Cali Dengue is a viral disease transmitted by the Aedes aegypti mosquito, which thrives in tropical urban environments like Cali. Symptoms include high fever, severe headache, joint and muscle pain, rash, and in severe cases, dangerous bleeding. With Cali's risk score of 67 out of 100, residents and visitors should take prevention seriously. Local Risk Factors in Cali: Cali's warm climate (average 24°C year-round), frequent rainfall, and dense urban neighborhoods create ideal breeding conditions for mosquitoes. Standing water in open containers, discarded tires, uncovered water tanks, and poorly maintained drainage systems significantly increase mosquito populations. The city's informal settlements with limited waste collection face higher exposure risk. Actionable Prevention Steps: 1. Eliminate standing water around your home. Empty, clean, or cover water storage containers, flower pots, buckets, and pet bowls at least once per week. Mosquitoes lay eggs in clean, stagnant water as small as a bottle cap. 2. Use insect repellent containing 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 and use bed nets if sleeping areas are not fully enclosed. Repair any holes in existing screens. 4. Wear long-sleeved shirts and long pants during peak mosquito hours, particularly in neighborhoods near the Cali River and areas with poor sanitation. 5. Report mosquito breeding sites to local health authorities. Participate in community cleanup campaigns organized by the Secretaría de Salud Municipal. Collective action in your neighborhood reduces risk for everyone. If you develop sudden high fever with severe headache or joint pain, seek medical attention immediately. Avoid self-medicating with aspirin or ibuprofen, as these can worsen bleeding complications.
