Malaria Prevention on a Tanzania Safari: What to Know

Malaria is one of the first things people ask us about when they start planning a safari, and it is a fair question. The disease is present in most of Tanzania, including the national parks of the northern circuit, Zanzibar and the coast. The good news is that it is largely preventable, and thousands of travelers enjoy safaris every year without any problem.

Prevention works best as a combination of measures rather than relying on one thing. Below we explain how our guides and guests approach it in the field, so you can arrive prepared and then relax and enjoy the wildlife.

Where and when the risk is highest

Malaria is spread by the bite of infected Anopheles mosquitoes, which feed mainly between dusk and dawn. Risk is generally higher in warm, low-lying and humid areas, and it tends to rise during and after the rainy seasons, when standing water gives mosquitoes places to breed.

Higher ground such as the rim of the Ngorongoro Crater is cooler and has fewer mosquitoes, but no part of a typical safari route should be treated as risk-free. Plan your protection for the whole trip, including Arusha, Moshi and any beach time on Zanzibar.

Talk to a travel clinic before you book flights

Antimalarial medication is very effective, but the right choice depends on your health, other medicines you take, your age, pregnancy and the length of your trip. That is a conversation for a doctor or travel clinic, ideally six to eight weeks before departure, so there is time to start any course that needs to begin before you travel.

Bring your full itinerary to the appointment, including any Kilimanjaro climb or Zanzibar extension. Ask how to take your tablets, what side effects to expect and, importantly, how long to keep taking them after you leave Tanzania. Many people forget that last part, and finishing the course matters.

Avoiding bites in the bush

Medication lowers risk, but avoiding bites is your first line of defense. These habits make a real difference on safari:

• Apply an effective insect repellent to exposed skin from late afternoon onward, reapplying as directed on the label.
• Change into long sleeves, long trousers and socks for sundowners and dinner.
• Sleep under a mosquito net where one is provided and tuck it in properly.
• Keep tent flaps and windows zipped, especially when lights are on in the evening.
• Apply sunscreen first and repellent on top if you are using both.

What lodges and camps do

Most safari lodges and tented camps take mosquitoes seriously. Rooms usually have nets or screened windows, and many camps spray or provide plug-in devices in the evening. Our guides will also remind you when it is time to cover up, because the golden hour around sunset is exactly when mosquitoes become active.

Even so, accommodation varies, so pack your own repellent rather than assuming it will be provided. A small, light travel net can be useful if you are adding independent nights in town.

Know the symptoms after you get home

Malaria can appear days, weeks or occasionally months after you return. Early symptoms often feel like flu: fever, chills, headache, aches and tiredness. If you feel unwell with a fever during your trip or after you return, see a doctor promptly and tell them you have been in Tanzania. Prompt testing and treatment is what matters most, so do not wait to see if it passes.
