Key points
- Seek travel health advice at least 4–6 weeks before departure [2].
- Malaria is the leading preventable risk: the WHO African Region carries about 95% of the world’s malaria cases and deaths [1].
- Any fever within 12 months of returning from a malaria-risk country needs urgent medical assessment [4].
- Altitude sickness can begin above about 2,500 metres; Kilimanjaro rises to 5,895 m and Mount Kenya to 5,199 m [7, 8, 9].
- Since 1 October 2026, foreign visitors to Tanzania must hold a USD 44 inbound travel insurance policy [11].
Introduction
A safari is among the most rewarding forms of travel, and most of its health risks are predictable and preventable. Malaria remains the most serious of them: in 2024 the World Health Organization (WHO) estimated 282 million malaria cases and 610,000 deaths worldwide, about 95% of them in the WHO African Region [1]. Other common problems, such as travellers’ diarrhoea, sunburn and altitude sickness, are largely avoided with simple preparation.
This article opens a weekly Safari Health series written jointly by a physician and a safari guide. Each question is answered twice: once on the medical evidence, and once from three decades of practice in the field.
1. Which vaccinations do I need?
The doctor says: Book a consultation with a travel health clinic at least 4–6 weeks before departure, because some vaccines need more than one dose or time to become effective [2]. Make sure routine vaccinations, such as measles, are up to date. Vaccines commonly considered for travel include hepatitis A, typhoid, and a combined tetanus, diphtheria and polio booster; the right set depends on your destination, itinerary and medical history [2].
Yellow fever needs particular attention. Under the International Health Regulations, countries may require proof of yellow fever vaccination on the International Certificate of Vaccination or Prophylaxis [2, 3]. A single dose gives lifelong immunity; protection develops within 10 days in 80–100% of people and within 30 days in more than 99% [3]. Requirements differ between countries and depend on where you arrive from, so ask your clinic to check them for every country on your route.
The guide says: Carry your yellow fever certificate with your passport, not in checked luggage. You may be asked for it at airports and at land borders between countries.
2. How do I avoid malaria?
The doctor says: Prevention rests on two measures: avoiding mosquito bites and, where advised, taking antimalarial medicine [1, 4]. Your doctor will choose a medicine that suits your health, your other medicines and your itinerary. It usually starts a few days or weeks before travel and continues for a few weeks after return [4]. Use a repellent containing DEET (the NHS advises 50% DEET), IR3535 or icaridin; sleep under an insecticide-treated net; and wear long sleeves and trousers in the evening [1, 4].
Symptoms usually appear 7 to 18 days after an infective bite, but can take months [4]. If you develop a fever or flu-like illness within 12 months of visiting a malaria-risk country, seek medical care urgently and say where you have travelled [4]. Malaria is a medical emergency [4].
The guide says: Mosquitoes are most active from dusk until dawn. Apply repellent before evening drinks around the campfire, change into long sleeves at sunset, and check that the net around your bed is tucked in.
3. What can I safely eat and drink?
The doctor says: Drink bottled or treated water, and clean your hands before eating. If diarrhoea develops, the priority is fluid replacement: drink small, frequent amounts, and use oral rehydration salts, which a pharmacist can supply before you leave [5]. Diarrhoea in adults usually settles within 5–7 days. Seek medical care if there is blood in the stool, if you cannot keep fluids down, if signs of dehydration persist despite oral rehydration, or if diarrhoea lasts more than 7 days [5].
The guide says: Our safari vehicles carry drinking-water tanks, and every guest receives a refillable bottle, so safe water is always to hand on game drives [13]. Lodge and camp kitchens are used to international guests; if you would like to try local roadside food, ask your guide where to go.
4. How do I manage sun and heat?
The doctor says: Safari areas lie close to the Equator, where solar radiation is intense even on cool days. Use a sunscreen of at least SPF 30 with a UVA rating of at least four stars, reapply it every two hours and after sweating, and add a wide-brimmed hat and sunglasses [6]. Drink regularly through the day.
The guide says: In an open-roof vehicle you may spend several hours in direct sun. Early mornings, however, can be cold, so dress in layers that you can remove as the day warms up.
5. Will altitude affect me?
The doctor says: Altitude sickness can occur above about 2,500 metres, especially after a rapid ascent. Symptoms include headache, nausea, fatigue, dizziness and poor sleep, usually starting 6–10 hours after arrival [7]. The NHS advises not travelling from below 1,200 m to above 3,500 m in a single day; above 3,000 m, not sleeping more than 500 m higher than the previous night; and taking a rest day every 3–4 days. If symptoms worsen or do not improve after a day, descend 300–1,000 m; confusion or breathlessness at rest require immediate descent and medical help [7].
These rules matter on East Africa’s high peaks: Kilimanjaro reaches 5,895 m [8] and Mount Kenya’s highest summit, Batian, 5,199 m [9]. Anyone with a heart or lung condition should discuss a high-altitude trip with their specialist before booking.
The guide says: On Kilimanjaro, route choice is acclimatisation. Routes range from about five to eight days [14], and the longer ones give the body more time to adjust. We match the route to each guest’s fitness.
6. Can I travel with diabetes, a heart or a lung condition?
The doctor says: In most cases yes, with planning. For diabetes, carry two to three times your usual supply of insulin or other medicines and equipment, divided between separate bags, together with a letter from your healthcare team listing your medicines and devices [10]. Keep insulin and sensors in hand luggage, store insulin in a cool bag that does not freeze it, and do not use insulin that has changed in appearance [10]. Carry snacks to cover delays [10]. People with lung conditions should plan their medicines and travel insurance well in advance [15], and anyone with a heart or lung condition should obtain specialist advice before booking.
The guide says: Tell us about any medical condition when you book. We can plan shorter drives, use a private vehicle, and choose lodges closer to medical facilities. Game-drive tracks can be dusty in the dry season, so guests with asthma should keep their inhaler within reach and bring a scarf or face covering.
7. What insurance do I need?
The doctor says: Buy comprehensive travel medical insurance that covers emergency evacuation and repatriation, and declare all pre-existing conditions when you buy it.
The guide says: Our guests are covered for emergency air evacuation in East Africa, our guides are trained in first aid, and our vehicles carry radio communication [12]. For Tanzania there is now a legal requirement as well: since 1 October 2026, every foreign visitor must hold a USD 44 inbound travel insurance policy covering medical emergencies for up to 92 days. It is sold by the National Insurance Corporation for arrivals on the mainland and by the Zanzibar Insurance Corporation for arrivals in Zanzibar [11].
Before you travel: checklist
| When | Action | Source |
|---|---|---|
| 4–6 weeks before | Travel health consultation; vaccines; antimalarial prescription if advised | [2, 4] |
| At least 10 days before | Yellow fever vaccination, if required or recommended for your route | [3] |
| Before booking | Insurance with evacuation cover; specialist advice for heart or lung conditions | [12, 15] |
| Before departure (Tanzania) | Buy the USD 44 inbound travel insurance | [11] |
| Packing | Repellent, sunscreen SPF 30+, oral rehydration salts, double or triple medicine supply in hand luggage | [4, 5, 6, 10] |
| Up to 12 months after return | Any fever: seek medical care urgently and mention your travel | [4] |
Conclusion
Most safari health problems are preventable with early advice, sensible daily habits and the right insurance. Start preparing at least four to six weeks before departure, take malaria prevention seriously, ascend gradually at altitude, and tell your safari operator about any medical condition. Prepared this way, travellers can focus on what they came for: Africa’s wildlife and landscapes.
