Malaria risk in Douala

Malaria Prevention Guide: Douala, Cameroon Malaria is a life-threatening disease caused by Plasmodium parasites transmitted through the bite of infected Anopheles mosquitoes. In Douala, the risk score of 70/100 reflects its tropical climate, high humidity, extensive wetlands, and urban waterlogging from seasonal rains, creating ideal conditions for mosquito breeding. Peak transmission occurs during the wet season (March to November), though risk persists year-round due to the consistently warm temperatures. Local risk factors in Douala include the Wouri River basin and surrounding swamps, which serve as prime mosquito breeding sites, rapid urbanization with inadequate drainage, and high population density facilitating transmission. Actionable prevention steps: 1. Use insecticide-treated bed nets (ITNs) every night. Ensure nets are intact and properly tucked under mattresses. Re-treat nets as recommended. This single step reduces transmission risk significantly. 2. Apply DEET-based repellents on exposed skin from dusk to dawn when mosquitoes are most active. Wear long-sleeved clothing and pants during these hours. Eliminate standing water around your home to reduce breeding sites. 3. Use indoor residual spraying (IRS) if available in your area. Keep windows and doors screened or closed during peak mosquito hours. Consider spatial repellents in sleeping areas. 4. Take antimalarial prophylaxis as prescribed by a healthcare provider. Common options include doxycycline, atovaquone-proguanil, or mefloquine. Start before travel and continue as directed. 5. Seek immediate medical attention if you develop fever, chills, headache, or body aches. Malaria symptoms can appear 7 to 30 days after a mosquito bite. Early diagnosis and treatment are critical to prevent severe complications.
