Zanzibar Health Guide 2026: Malaria, ZIC Insurance, Medical Facilities

At Michamvi we sometimes see guests who worry more about malaria than necessary — and others who have never heard of the ZIC insurance. Both are avoidable with fifteen minutes of preparation.

The ZIC mandatory insurance — what it is, what it costs, what it covers

Since 1 October 2024, ZIC inbound insurance is mandatory for all foreign visitors to Zanzibar.

What it is: A government-mandated insurance product of the Zanzibar Insurance Corporation (ZIC) — not comparable to a standard travel insurance policy. It is a statutory entry requirement.

What it costs:

Validity: Up to 92 days from entry.

Where to buy: Exclusively at inbound.visitzanzibar.go.tz — no third-party products or other providers are accepted.

Entry check: The QR code from your ZIC certificate is checked at multiple points on arrival, starting in the jetway before you reach immigration. Arriving without proof means purchasing on the spot or, in some cases, being refused boarding by airlines that integrate the system at departure check-in.

What the ZIC does NOT replace

This is the most common mistake: the ZIC has limited coverage (approximately USD 50,000 medical) and is NOT a comprehensive travel insurance policy. Not buying it is not an option — but it does not replace your own private travel health cover.

You need both:

1. ZIC insurance (mandatory, for entry)
2. Your own travel health insurance (for full coverage, medical evacuation, repatriation)

European public health insurance schemes do not cover medical costs outside the EU — private travel health insurance is essential for Zanzibar.

Malaria on Zanzibar — a realistic assessment

Zanzibar has malaria — but the risk is significantly lower than mainland Tanzania, and government control programmes have reduced prevalence substantially over the past decades.

The facts:

• Malaria is present on Zanzibar (below 1,800m altitude — the island sits at 0–80m, so everywhere)
• Zanzibar-specific: malaria control on the island is stronger than on the mainland
• Nevertheless: malaria cases among European travellers returning from Zanzibar have been documented in a 2024 editorial
• Dengue fever is also present (daytime-biting mosquito)

Recommendation: Malaria prophylaxis for Zanzibar visits is recommended by travel medicine specialists. No prophylaxis medication is 100% effective — always combine:

• Malaria tablets (consult a travel medicine doctor)
• DEET insect repellent (evenings for the malaria mosquito, daytime for dengue)
• Sleep under a mosquito net (good hotels provide one — ask if unsure)

Recommended prophylaxis options for Zanzibar

• Atovaquone/Proguanil (Malarone): 1× daily, start 1–2 days before arrival, continue 7 days after return. Well tolerated.
• Doxycycline: 1× daily, start 1–2 days before arrival, continue 4 weeks after return. Photosensitising — use sunscreen diligently. Not suitable during pregnancy.

Consult a travel medicine clinic 4–6 weeks before departure, not a general practitioner without tropical medicine training.

Malaria risk by season

Malaria risk on Zanzibar is not static through the year. Risk is higher during and immediately after the rainy seasons — March to May (long rains) and November (short rains) — when standing water increases mosquito breeding. The dry months of June to October and January to February carry lower seasonal transmission risk, but prophylaxis is still recommended year-round because the island sits at sea level and Anopheles mosquitoes are present throughout.

Dengue fever — the daytime mosquito risk

Dengue fever deserves its own section because the protection strategy differs entirely from malaria.

What dengue is: A viral infection transmitted by the Aedes aegypti mosquito. Unlike the malaria-carrying Anopheles (which bites primarily in the evening and at night), the dengue mosquito is active during daylight hours — particularly in the early morning and late afternoon.

The key difference for travellers: There is no prophylaxis medication and no vaccine available for most short-stay tourists. DEET repellent is the only reliable prevention tool.

Protection protocol for Zanzibar:

• Apply DEET repellent containing at least 20% DEET every morning before going outside — not just at dusk
• Wear long sleeves and long trousers during early morning and late afternoon hours when Aedes activity peaks
• Choose accommodation with window screens or air conditioning (which keeps windows closed)
• A UV rash guard or swim shirt worn while snorkelling also provides protection in outdoor daytime settings

Symptoms: High fever appearing 4–10 days after a bite, severe headache, muscle and joint pain (dengue is nicknamed “breakbone fever”), rash. If you develop these symptoms within 2 weeks of returning from Zanzibar, tell your doctor you were in a dengue-endemic area. Seek medical attention immediately if suspected while still on the island.

I always apply DEET every morning at Michamvi — not just in the evening. The daytime biting pattern of dengue is the one thing most visitors don’t know until they’ve already been bitten.

Vaccinations

Yellow fever: Required ONLY for travellers arriving from yellow fever risk countries (parts of Africa, South America) or transiting there for more than 12 hours. For direct flights from Europe and North America: not required. The certificate is valid for life once issued.

Recommended boosters:

None of the above are mandatory for entry — only yellow fever (if arriving from a risk country).

Medical facilities on Zanzibar

Mnazi Mmoja Hospital (Stone Town)

Zanzibar’s only public hospital. Address: Kaunda Road, Stone Town. Emergency care is possible, but capacity for complex cases is limited.

Aga Khan Dispensary (Stone Town)

Private health centre — modernised facility with imaging (X-ray, ultrasound), laboratory services, and improved emergency capacity. For private patients. The best option for non-emergency medical issues on the island.

Zanzibar Hyperbaric Chamber (DAN)

The only decompression chamber in all of Tanzania, managed by DAN (Divers Alert Network). For diving accidents (decompression sickness). Contact details from DAN Africa or local PADI dive schools.

Pharmacies

Available in Stone Town. Quality and availability vary significantly. Bring your own medications from home — especially malaria prophylaxis, antibiotics, and anything prescription-based.

Malaria prophylaxis timing — the numbers that matter

This is worth its own section because the timing catches many travellers off guard. Starting tablets at the airport is already too late.

Malarone (atovaquone/proguanil):

• Start: 1–2 days before your first day in Zanzibar
• During: once daily throughout your stay
• After: continue for 7 days after you return home
• Note: well-tolerated by most travellers; the 7-day tail is the shortest of the prophylaxis options

Doxycycline:

• Start: 1–2 days before your first day in Zanzibar
• During: once daily throughout your stay
• After: continue for 4 weeks after you return home — the long tail is not optional
• Note: causes photosensitivity (increased sun sensitivity); apply SPF 30+ daily. Not recommended during pregnancy.

Both options require a prescription. Fill the prescription before you leave home — pharmacies in Stone Town carry some medications but supply is inconsistent. Do not assume you can source your prophylaxis tablets on Zanzibar.

The 4-week tail on doxycycline trips up return travellers regularly. I’ve met people who stopped their tablets on the flight home, developed malaria two weeks later, and had no idea Zanzibar was connected to the symptom.

Sunscreen and sun protection

Zanzibar sits 6 degrees south of the equator. UV radiation is significantly stronger than at European or North American home latitudes — and the sea breeze makes it easy to underestimate.

Minimum standard: SPF 30+ broad-spectrum sunscreen, reapplied every 2 hours. If swimming or sweating heavily, reapply more frequently — most sunscreen is effectively gone after 40–80 minutes in water regardless of what the label says.

Reef considerations: There is no regulated standard for “reef-safe” sunscreen labels — the term is not defined by any regulatory body. However, avoiding oxybenzone and octinoxate is the most commonly cited precaution by marine biologists. Mineral-based sunscreens (zinc oxide, titanium dioxide) are a practical alternative. A UV rash guard worn while snorkelling provides sun protection and removes sunscreen from the equation entirely.

Practical reality on Zanzibar: Quality sunscreen is hard to find outside Stone Town pharmacies, and expensive when available. Bring a full supply from home for the duration of your trip.

Common health risks

Sunburn: Tropical sun is more intense than at home latitudes. Apply SPF 30+ daily, reapply every 2 hours (more often after swimming). A wide-brim hat matters from day one — sea breezes mask the intensity.

Traveller’s diarrhoea: Do not drink tap water — use sealed bottled water or filtered/boiled water. Bring oral rehydration salts (ORS) — the best first-line treatment for diarrhoea. Most tourist restaurants in Stone Town use purified water for drinks and ice.

Diving: Decompression issues → contact the Zanzibar Hyperbaric Chamber immediately. Before a dive holiday: check your DAN membership covers Tanzania or purchase AMREF Flying Doctors Medevac.

Rabies: Do not touch wildlife. In the event of a bite (dog, bat, monkey): immediately wash the wound thoroughly with water and soap for at least 15 minutes, then seek medical attention urgently. Rabies is almost 100% fatal once symptoms appear — post-exposure prophylaxis must begin within 24–72 hours.

Heat exhaustion: Midday heat (12:00–15:00) in peak months can exceed 35°C with high humidity. Rest in the shade or in air-conditioned spaces during these hours, especially in the first 2–3 days of acclimatisation.

Food and water safety

Zanzibar has excellent food — but water and food hygiene deserve attention, particularly outside the main tourist areas.

Drinking water: Never drink tap water on Zanzibar. This applies to brushing teeth as well — use bottled or boiled water for brushing. Sealed bottled water is widely available. Avoid tap water in ice unless you know it came from a purified source. Most tourist restaurants in Stone Town use purified water for ice and cooking — at street stalls and smaller establishments, stick to sealed bottles.

Seafood: Fresh seafood on Zanzibar is generally excellent when genuinely fresh — the island’s fish markets are supplied daily. A practical rule: ask when it was caught and trust an honest, direct answer. Seafood that has been sitting unrefrigerated in the heat carries risk.

Street food: The Forodhani Night Market in Stone Town is well-regulated and safe — it operates under municipal oversight and has a strong track record. At other street stalls: prefer grilled items prepared in front of you and freshly cooked food over pre-prepared dishes sitting at ambient temperature.

Fruit: Peeled fruit (mango, avocado, papaya) is safe. Uncooked salads in budget restaurants: exercise caution because washing water quality is variable. Zanzibar’s tropical fruit is genuinely outstanding — whole peeled mangoes and fresh coconut from roadside vendors are both safe and among the best things you’ll eat on the island.

I eat street food at Forodhani without hesitation. I don’t drink tap water anywhere on the island, including in hotels without a filtered water system.

Emergency numbers

Before you travel: Save your travel insurance hotline, AMREF Flying Doctors contact (if you hold their cover), and the ZIC emergency line ([email protected] / 24h: +331701957025) in your phone.

AMREF Flying Doctors — how medevac works

AMREF Flying Doctors provides 24-hour air ambulance and evacuation services covering Zanzibar and mainland Tanzania. In a serious medical emergency — a diving accident, severe illness, or major trauma — evacuation to Nairobi (where Level-4 hospital care is available) can be life-critical.

What AMREF is (and is not): AMREF is not standard health insurance. It is an emergency medical evacuation service that provides transport, flight stabilisation, and assessment. It operates alongside, not instead of, your regular travel health insurance.

Costs for Zanzibar:

• Extended regional rate (all Tanzania including Zanzibar): USD 45 per person for up to 14 days, USD 60 for up to 2 months
• AMREF’s 24-hour emergency line: +254 20 699 2299 (international) or +255 684 818 071 (Tanzania)

How to purchase: at amref.org before departure. The card should be accessible in your wallet — not buried in your luggage.

Divers specifically: DAN membership (Divers Alert Network) covers decompression sickness and diving accidents worldwide — the Zanzibar hyperbaric chamber bills DAN directly. DAN membership starts at approximately USD 35/year and is the standard cover for any dive trip.

First-aid kit for Zanzibar

Pharmacies are available in Stone Town but quality and supply are unpredictable. Bring these from home:

Essential:

• Malaria prophylaxis (Malarone or Doxycycline — prescription required)
• DEET insect repellent 50% (liquid, not spray — lasts longer, doesn’t evaporate as fast)
• Oral rehydration salts (ORS) — most important item for diarrhoea
• Broad-spectrum antibiotic (Azithromycin 500mg, prescription required) — for severe traveller’s diarrhoea

Recommended:

• Sunscreen SPF 30+ (good quality is hard to find on Zanzibar and expensive when available)
• Painkillers (ibuprofen/paracetamol)
• Plasters and wound disinfectant (reef wounds)
• Anti-diarrhoeal (loperamide — for situations where toilet access is limited)
• Eye drops (chloramphenicol) — conjunctivitis is common in tropical climates
• Mosquito net (for accommodation without one)
• Reef shoes (protect against sea urchins and sharp reef)

Swimming and ocean risks

Sea urchins: The most common physical hazard in the reef. Sea urchins hide in coral rubble in shallow water at low tide. A single step without reef shoes leads to spines in the foot. Treatment: heat (hot water, not burning), remove spines with tweezers, disinfect. Persistent cases: see a doctor.

Jellyfish: More frequent in certain months (October–November, monsoon transitions). Painful but not life-threatening in East African waters. Treatment: scrape tentacles off with a card (not fingers), rinse with saltwater, apply vinegar if available — no fresh water, no rubbing.

Currents: Outside the reef, currents can be strong — particularly on an outgoing tide. In open water: if you feel a current pulling you offshore, do not swim against it (exhaustion). Swim sideways to the current, parallel to the beach, until you exit it.

East coast swimming: The east coast is tide-dependent — at low water the sea retreats 200–400 metres. Swimming is best around high tide. See the east coast tidal guide for timing.

Food safety

Drinking water: No tap water. Use sealed bottled water or a water filter. Ice in tourist restaurants is typically from purified water — at street stalls: skip the ice to be safe.

Seafood: Fresh seafood on Zanzibar is generally excellent when it is genuinely fresh. A good rule: ask when it was caught. An honest vendor answers directly. Seafood that has been sitting in the heat: avoid.

Street food: Forodhani Night Market in Stone Town is well-regulated and safe. At other street stalls: prefer grilled items and freshly prepared food (visible cooking) over pre-prepared dishes sitting in the heat.

Fruit: Peeled fruit (mango, avocado, papaya) is safe. Uncooked salads in budget restaurants: exercise caution (washing water quality varies).

Safari + Zanzibar combo health notes

Visitors combining a Tanzania mainland safari with Zanzibar have additional health considerations:

Altitude (Ngorongoro / Kilimanjaro): The Ngorongoro crater rim sits at ~2,300m — altitude headaches possible with rapid ascent. For Kilimanjaro climbers: read the AMS protocol; discuss Diamox (acetazolamide) with your travel medicine doctor.

Wildlife risks on safari: Never leave the vehicle without a guide. Safari camps enforce rules for a reason — incidents involving elephants or lions happen almost exclusively when rules are broken.

Malaria on the mainland: Mainland Tanzania (Serengeti, Tarangire) has HIGHER malaria risk than Zanzibar island. If you planned prophylaxis only for the beach portion, ensure your course covers the mainland days too — start Malarone tablets accordingly earlier.

Travel insurance: what you actually need

For Zanzibar, you need three independent insurance components — often combined into one product:

1. ZIC mandatory insurance (required): USD 44/person. Buy directly at inbound.visitzanzibar.go.tz. No third parties. The QR code is checked at arrival — without ZIC you cannot enter.

2. Travel health insurance (essential, because local public health cover doesn’t apply): Serious treatment on Zanzibar: Aga Khan Dispensary is good but expensive. For more serious conditions (surgery, dental): repatriation to Nairobi or Europe. Costs escalate quickly above USD 15,000. Annual policies from EUR 80–150; single-trip cover for 14 days from EUR 10–30.

3. AMREF Flying Doctors Medevac (strongly recommended): USD 45/person for up to 14 days (extended Tanzania + Zanzibar regional rate). Covers air evacuation to Nairobi (Level-4 hospital). In the event of a serious accident or severe illness on Zanzibar or Mafia Island, this evacuation can be life-critical. Purchase at amref.org.

Divers: DAN membership (Divers Alert Network) covers decompression sickness and diving accidents worldwide — the Zanzibar chamber bills DAN directly. From approximately USD 35/year.

The British Protectorate (1890–1963) brought the infrastructure Stone Town now partly relies on — Mnazi Mmoja Hospital stands on a site developed during that era. The Zanzibar history guide covers the full arc — from Arab traders in the 7th century through the 38-minute Anglo-Zanzibar War of 1896 (the world’s shortest war) to the 1964 revolution that formed Tanzania — including the historical sites you can visit in Stone Town.
