Health and Safety in Tanzania: What to Sort Before You Fly

Malaria, which is the everyday risk

Malaria is endemic across most of the country, including Zanzibar and the safari parks, and it is the health risk a visitor is most likely to actually meet. The exception is genuine altitude — the upper slopes of Kilimanjaro and the highest ground are above the mosquito's range — but the towns you pass through on the way are not. Treat the whole trip as a malaria area unless a doctor tells you otherwise.

Prophylaxis is a prescription decision and belongs with a travel clinic or a doctor several weeks before departure, not with a guidebook: the options differ in side effects, in how long before and after travel they must be taken, and in suitability for pregnancy, children and existing conditions. Book that appointment early enough that a course which needs starting in advance can actually be started.

Alongside the tablets, the bite avoidance does real work and is often neglected. The mosquito that carries malaria bites from dusk through the night, which is exactly when you are sitting outside at camp: cover arms and ankles after sunset, use repellent on exposed skin, and sleep under the net that every camp and lodge provides, tucked in properly rather than draped. And know the one fact that matters afterwards — malaria can present weeks after you get home, so any fever within three months of return needs a doctor told that you were in East Africa.

Kilimanjaro: altitude, and the number of days

Kilimanjaro is marketed as the mountain anyone can climb, and the technical part of that is true — the standard routes need no ropes, no climbing skill and no previous mountaineering. The altitude part is not gentle at all. The summit is at 5,895 metres, higher than any point in Europe or the contiguous United States, and altitude sickness is common, unpredictable by fitness, and occasionally fatal on this mountain in ordinary years.

The single variable that most affects both your chance of summiting and your safety is the number of days you spend ascending. A five-day itinerary gives the body almost no time to acclimatise and has a markedly lower success rate; seven, eight or nine days on a route with a good acclimatisation profile transforms both numbers. The shorter itinerary is cheaper for a reason, and the reason is that you are less likely to reach the top and more likely to get ill. Choose days over price, and choose an operator that builds in an acclimatisation day rather than one that offers the fastest ascent — the routes and how their profiles differ are compared in the Kilimanjaro climbing guide.

On the mountain, the rules are simple and the discipline is everything: ascend slowly even when you feel fine, drink far more water than seems necessary, tell your guide about headache, nausea, dizziness or breathlessness at rest rather than pushing through, and understand that descent is the treatment for altitude sickness. Reputable operators carry oxygen and a pulse oximeter and check climbers daily; ask about that before booking. Being turned around by a guide is not a failure, and the guides who do it are the good ones.

Animals, which are the point and not the danger

Safari involves being close to large wild animals, and the safety record is excellent because the rules are good and almost everyone follows them. Stay in the vehicle unless your guide says otherwise — animals read a vehicle as a single non-threatening shape and a standing human as something else entirely, which is why standing up through the roof at the wrong moment is genuinely dangerous rather than merely discouraged. Keep your voice down, never feed anything, and do exactly what the guide says immediately, without discussion, if they say it sharply.

In camp the rules matter more, not less. Many camps are unfenced by design, animals move through them at night, and this is why staff escort guests to tents after dark and why you do not walk between tents alone. Zip the tent fully. Keep food out of it. Baboons and monkeys around lodges are habituated, bold and capable of taking things from an open hand or an open room, and they are the animal most likely to cause a visitor an actual problem.

In the water, hippopotamus and crocodile make lakes and rivers genuinely dangerous — hippos kill more people in Africa than any other large animal, and they are aggressive near water at night when they come out to graze. Never swim in fresh water unless it is explicitly established as safe; that also covers bilharzia, a parasite present in many lakes. On the coast the sea is a different picture and swimming is straightforward, with the usual attention to currents and to reef shoes over sharp coral.

Distance, insurance and the practical layer

Good hospitals exist in Dar es Salaam and to a lesser extent in Arusha, and that is roughly the extent of it. A safari camp may be several hours from a road and a short flight from a town, which means a serious medical problem is answered by air evacuation rather than by an ambulance. That is a routine, well-practised procedure here — and it is expensive, and it is what your insurance is for.

So read the policy rather than the summary. It needs to cover medical evacuation explicitly, it needs to cover the altitude you will actually reach if you are climbing — many standard policies cap trekking cover well below Kilimanjaro's summit — and it needs to cover diving if you intend to dive off Zanzibar or Pemba. Separately, Zanzibar requires its own designated insurance for entry, which is a different requirement covered in this country's visa guide and does not replace a proper travel policy.

One legal point sits outside the medical picture and is worth knowing because the penalty is severe and the offence is easy to commit innocently: buying or attempting to export wildlife products — skins, horns, ivory, shells, certain seeds and hardwoods — without certified permits is a criminal matter, and foreign travellers have been arrested at the border for souvenirs they did not realise were prohibited. If a market stall is selling something that was recently an animal, assume you cannot take it home.

The rest is straightforward. A yellow fever certificate is required for entry from countries with transmission risk and is worth having regardless if your route includes one; a travel clinic will also review typhoid, hepatitis and tetanus. Drink bottled or treated water throughout. Petty theft is the realistic crime risk in the cities — ordinary precautions with bags, phones and night walking are enough — and the motorbike taxis that are so useful in traffic are the single most dangerous vehicle you can get on here, with helmets rare and casualties routine. Take the three-wheeler instead.
