Malaria risk in Cotonou

Malaria is a serious mosquito-borne disease caused by parasites transmitted through the bites of infected Anopheles mosquitoes. In Cotonou, the climate creates ideal breeding conditions for these mosquitoes, making prevention essential for residents and visitors.

Cotonou's risk score of 71/100 reflects several local factors. The city's tropical climate, with high humidity and temperatures around 25-30°C, supports year-round mosquito breeding. Frequent rainfall and poor drainage in many neighborhoods create extensive standing water pools. The lagoon and surrounding wetlands add to the challenge. Urban density means mosquitoes thrive in small water collections in tires, containers, and construction sites. Nighttime outdoor activities increase exposure during peak mosquito biting hours.

Take these practical steps to protect yourself.

Use insect repellent containing DEET, picaridin, or oil of lemon eucalyptus on exposed skin, especially from dusk to dawn when mosquitoes are most active.

Sleep under insecticide-treated bed nets every night, ensuring they are properly tucked under mattresses without holes or gaps.

Eliminate standing water around your home. Empty flower pots, buckets, tires, and any containers weekly. Cover water storage containers tightly.

Wear long sleeves and pants during evening hours when mosquitoes are active, and use air conditioning or window screens to keep mosquitoes outdoors.

Consult a doctor about antimalarial medication if traveling to rural areas around Cotonou or staying long-term. Take prescribed doses consistently.

Seek immediate medical attention if you develop fever, chills, headache, or body aches, as early treatment prevents severe complications.
