Malaria, Yellow Fever and the Zanzibar–Mainland Crossing

Malaria: the risk that matters

Yellow fever is mostly a non-issue for this trip. Malaria is not, and the reassuring part is that the day trip does not change what you should already be doing.

Both Zanzibar and Mikumi are malaria-risk areas. TravelHealthPro classes all of Tanzania below 1,800 metres as high risk, and names Zanzibar explicitly; Mikumi’s low-lying floodplain sits well below that line. So you should already be taking malaria precautions on Zanzibar. The Mikumi day trip does not add a new category of risk, and the same precautions cover you in both places.

This needs saying because a lot of Zanzibar marketing implies the island is effectively malaria-free. It is not. Official guidance still classes it as a risk area and recommends precautions, and there have been outbreaks in recent years.

What to do about it:

Take an antimalarial. The commonly recommended options are atovaquone-proguanil (Malarone), doxycycline and mefloquine. Which one suits you depends on your medical history, the length of your trip and other factors, and that is a decision to make with a clinician. Each has its own schedule for when to start and how long to continue after you leave the risk area, so start the conversation early. Mefloquine in particular needs a couple of weeks’ head start.

Avoid bites, which matters as much as the tablets. No antimalarial is fully protective, so bite avoidance is essential alongside it. Use a repellent containing DEET or picaridin, cover up with long sleeves and trousers, especially from dusk to dawn when the malaria mosquito feeds, and choose accommodation with screens or air conditioning.

Watch for fever afterwards. Malaria symptoms (fever, chills, headache, aches) can appear from about a week to as much as a year after the bite. If you develop a fever during your trip or within a year of coming home, seek medical care urgently and tell the doctor you have been to Tanzania, so they test for malaria. Malaria mistaken for flu has killed returning travellers. If you remember one thing from this page, make it this.

Other health notes for this trip

Routine and recommended vaccines. Make sure your routine immunisations are up to date. Most travellers to Tanzania are advised to have hepatitis A and typhoid (both food- and water-borne) and a current tetanus booster, and a travel clinic will advise on others based on your plans. Sort this out weeks ahead, because some vaccines need time to take effect.

Tsetse flies in the park. Mikumi has tsetse flies. Their bite is painful, and they are drawn to dark colours, especially dark blue and black. The chance of catching sleeping sickness on a single day visit is very low, but it is not zero anywhere in East Africa’s game parks, and there is no vaccine or preventive drug: the only protection is avoiding bites. Wear neutral, light colours, and bear in mind that ordinary repellent works only partly against them. Our packing guide has the full clothing list.

Sun, heat and food. The Mikumi floodplain is hot and exposed, with little shade. Bring a hat, sunglasses, high-factor sunscreen and plenty of water. Stick to bottled or treated water, and eat the packed lunch from a reputable operator instead of roadside food.

Insurance. Separate from all of the above, remember Zanzibar’s mandatory entry insurance and, importantly, that it does not cover you on the mainland. Your own comprehensive travel insurance, ideally with medical evacuation, is what covers the safari itself. See Zanzibar’s Mandatory Travel Insurance and Your Safari.

What to do, and when

• Four to six weeks before travel: see a travel health clinic. Confirm routine vaccines, get hepatitis A and typhoid if needed, and agree an antimalarial and its schedule.
• Arrange yellow fever vaccination only if your routing requires it (arrival from or via a country with yellow fever risk) or a clinician advises it for your personal situation.
• Pack: repellent, neutral covering clothing, sun protection, and your full course of antimalarial tablets in their original packaging.
• Carry your yellow card only if you have one or have been in an endemic country.
• After you return: finish your antimalarial course, and treat any fever within a year as possible malaria, mentioning your Tanzania trip to any doctor.

None of this changes which safari you book: the day itself, on the most-reviewed Mikumi fly-in day trip or any other listing, carries the same malaria precautions you are already taking on Zanzibar. That trip includes return flights, park fees and a bush lunch for $430, and is rated 4.7/5 from more than 2,900 reviews.

Frequently asked questions

Do I need a yellow fever certificate for Zanzibar or Tanzania? Not if you arrived directly from a non-endemic country such as the UK, Europe or North America. You need one only if you arrived from, or transited for more than 12 hours through, a country with yellow fever risk, such as Kenya, Uganda or Ethiopia.

Does flying to Mikumi and back to Zanzibar require a yellow fever certificate? No. Zanzibar is part of Tanzania, so travel between the mainland and Zanzibar is domestic and triggers no certificate requirement.

Is there malaria in Zanzibar and Mikumi? Yes. Both are classed as malaria-risk areas, so take an antimalarial and avoid bites. The day trip does not change your risk category, because Zanzibar itself is already a risk area.

Which malaria tablets should I take? That is a decision for a clinician. The common options are Malarone, doxycycline and mefloquine, chosen to suit your circumstances.

What is the most important thing to remember? If you get a fever during your trip or within a year of it, seek care urgently and tell the doctor you were in Tanzania, so malaria can be ruled out.
