Dengue Fever risk in Hefei

Dengue Fever Prevention Guide for Hefei

What is Dengue Fever

Dengue Fever is a viral infection spread by Aedes mosquitoes, primarily Aedes albopictus. Symptoms include high fever, severe headache, joint and muscle pain, rash, and fatigue. Most cases are mild, but severe dengue can be life-threatening without proper care.

Hefei Local Risk Factors

Hefei has a moderate dengue risk score of 57/100. The city's subtropical humid climate supports mosquito breeding from May through October. Standing water in residential communities, parks along the Chaohu Basin, and urban green spaces create ideal habitats for mosquitoes. Summer temperatures between 25-35°C accelerate mosquito breeding cycles. Increasing international travel and rising regional cases in Anhui Province further elevate local transmission risk.

5 Actionable Prevention Steps

1. Eliminate standing water weekly. Empty flower pot saucers, discarded tires, and blocked drains around your home. Mosquitoes breed in stagnant water as small as a bottle cap.

2. Use repellent daily during peak hours. Apply DEET or picaridin-based repellent from dawn to dusk when Aedes mosquitoes are most active.

3. Install window screens and use bed nets. Repair damaged screens and sleep under nets if windows stay open during summer nights.

4. Report mosquito breeding sites to local health authorities. Contact Hefei CDC at 12320 for neighborhood inspections and community spraying programs.

5. Seek early medical attention. If you develop sudden high fever with pain behind eyes or severe joint ache, visit Anhui Provincial Hospital or local fever clinics immediately for NS1 antigen testing.
