Dengue Fever risk in Hong Kong

Dengue Fever Prevention Guide for Hong Kong (Risk Score: 66/100) Dengue fever is a viral infection transmitted by Aedes mosquitoes, primarily Aedes albopictus, causing high fever, severe headache, joint pain, and rash. In Hong Kong, the warm, humid climate from May to November creates ideal breeding conditions for these mosquitoes. Urban density, abundant green spaces, and frequent rainfall increase risk. Local Risk Factors: - Peak transmission: May to November (wet season) - Common breeding sites: Stagnant water in containers, flower pots, discarded tires, drains - Urban environments with dense population and green areas Immediate Prevention Steps: 1. Eliminate Standing Water Weekly Check and empty, scrub, or cover all containers holding water. Flower pot saucers, buckets, and drains are common breeding sites in Hong Kong apartments. 2. Apply DEET Repellent Daily Use 20-30% DEET repellent on exposed skin, especially during dawn and dusk when Aedes mosquitoes are most active in Hong Kong. 3. Install Window Screens and Nets Use air conditioning or properly fitted window screens. Sleep under treated mosquito nets if screens are unavailable. 4. Wear Protective Clothing Wear long sleeves and pants, particularly in green areas during peak hours. 5. Report Breeding Sites Contact Food and Environmental Hygiene Department hotline (2868 0000) for suspected breeding sites in public areas. Seek immediate medical attention for severe symptoms. Early detection is critical in Hong Kong's high-risk season.
