1. Understanding Malaria Risk in Tanzania

Malaria is transmitted through the bite of infected Anopheles mosquitoes, which are most active from dusk to dawn. In Tanzania, malaria is present in:

• Lowland areas: Dar es Salaam, Arusha, Moshi, and other cities below 2,000 meters.

• National parks: Serengeti, Tarangire, Ruaha, Mikumi, and Selous.

• Zanzibar: Coastal regions and islands have malaria risk, especially in rural areas.

High-altitude regions, including the summit of Mount Kilimanjaro, have negligible risk, but precautions are still recommended when traveling through lower elevations.

2. Who Should Take Malaria Prevention Tablets?

Malaria tablets are strongly recommended for all travelers visiting areas where malaria is endemic. This includes:

• Solo travelers exploring safaris or national parks.

• Families with children visiting rural or coastal regions.

• Travelers staying in hotels, lodges, or tented camps in lowland areas.

• Anyone planning overnight trips in areas with limited mosquito control.

Even if you primarily stay in urban hotels, malaria prophylaxis is advisable because mosquitoes can still enter accommodations at night.
