Malaria risk in Arusha

Malaria Prevention Guide – Arusha, Tanzania

Risk Score: 66/100

Malaria is a life-threatening disease caused by parasites transmitted through the bite of infected female Anopheles mosquitoes. Symptoms include high fever, chills, headache, and fatigue. Without prompt treatment, severe cases can lead to organ failure and death.

What makes Arusha particularly risky: The city sits at approximately 1,400 meters elevation, but surrounding lowland areas and seasonal rains from March through May and November through December create ideal breeding grounds for mosquitoes. Many residents and visitors travel to nearby lower-altitude zones like Arusha National Park and rural villages where transmission rates are significantly higher. Urban drainage ditches and standing water around homes and markets add to local exposure risk, especially during evening hours when mosquitoes are most active.

Prevention steps you can take starting today:

Sleep under a long-lasting insecticidal net every night. Make sure it has no holes, tuck it under your mattress, and replace it every three years or when it wears out. This single step reduces infection risk by up to fifty percent.

Apply DEET-based repellent on exposed skin from dusk to dawn. Reapply every four to six hours when outdoors, especially in rural areas and during evening social gatherings.

Wear long sleeves and trousers after sunset. Light-colored clothing makes mosquitoes easier to spot and removes less attractive to biting insects than dark colors.

Eliminate standing water around your home weekly. Empty containers, cover water storage, and keep gutters clean to reduce mosquito breeding near your family.

If you develop fever within two weeks of exposure, seek testing immediately. Early treatment saves lives and prevents severe complications.

Arusha's moderate elevation offers some protection compared to coastal and lowland regions, but complacency kills. Combine these steps consistently, especially during rainy seasons and when traveling to surrounding districts.
