Travel Health Guide (Nigeria to Abroad)

Staying healthy when travelling abroad — vaccines, malaria prevention, and travel insurance

Millions of Nigerians travel internationally for business, education, pilgrimage (Hajj and Umrah), and leisure. Each destination presents distinct health risks — from altitude sickness in Europe's mountains to traveller's diarrhoea, and vaccine requirements for entry. A pre-travel health visit 4–6 weeks before departure allows time for vaccines to take effect and prophylaxis to be arranged. This guide covers the essential travel health considerations for Nigerian travellers.

Signs and Symptoms

✓ Traveller's diarrhoea — the most common travel illness: loose stools, cramps, nausea

✓ Altitude sickness (AMS) — headache, nausea, shortness of breath at altitudes >2500m

✓ Jet lag — fatigue, insomnia, difficulty concentrating after crossing time zones

✓ Deep vein thrombosis (DVT) — calf pain and swelling after long flights

✓ Motion sickness — nausea, vomiting on flights, ships, or car journeys

✓ Sunburn — UV exposure at high altitude or unfamiliar climate

Risk Factors

Destination in a high malaria, yellow fever, or typhoid endemic region
Travelling during Hajj — meningococcal meningitis risk (Saudi mandate for MenACWY vaccine)
Backpacking or rural travel — higher food and water contamination risk
Pre-existing medical conditions — cardiovascular disease, diabetes, immunosuppression
Long-haul flights (>4 hours) — DVT risk
Pregnancy — restrictions on some vaccines and antimalarials

When to Seek Help

Pre-travel — 4–6 weeks before departureTravel health clinic visit — vaccination, prophylaxis, and health risk assessment

At destinationHigh fever, severe diarrhoea with dehydration, difficulty breathing, confusion — seek local emergency care immediately

On returnFever within 3 months of returning from a malaria-endemic area — ALWAYS a medical emergency. Seek malaria testing within 24 hours

On returnPersistent diarrhoea, weight loss, or blood in stool after travel — travel clinic or infectious disease assessment

Tests & Diagnosis

🧪 Pre-travel blood group confirmation

Know your blood group — important if requiring transfusion abroad

🧪 Malaria blood film or RDT on return

Mandatory for any fever within 3 months of return from Africa, South/Southeast Asia

🧪 Stool microscopy, culture, and ova/parasite exam

For persistent post-travel diarrhoea

🧪 HIV test if sexual exposure occurred

Free and confidential testing available

🧪 Yellow fever vaccination certificate

International Certificate of Vaccination or Prophylaxis (ICVP) — required for entry to many countries. Issued at designated centres in Nigeria

Treatment Options

Yellow fever vaccine — for Nigerian travellers going abroad

Required for Nigerians travelling to some countries as proof of yellow fever endemic origin. Also required for many countries if you have transited through Nigeria. Certificate valid for life. Get it at NAFDAC-approved yellow fever vaccination centres (LUTH, UCH, General Hospitals, some airports)

Malaria prophylaxis (for travel to non-endemic areas or re-exposure after leaving Nigeria)

Nigerians have partial immunity from lifelong exposure. However, immunity wanes after >6 months abroad. On returning to Nigeria after long absence, treat malaria as a risk. Nigerians travelling to high-risk destinations (Papua New Guinea, some parts of Asia): atovaquone-proguanil (Malarone) or mefloquine. Full prophylaxis with artemisinin ACTs is not prophylaxis — correct choice matters

Hajj health requirements — mandatory for Nigerian pilgrims

Meningococcal MenACWY vaccine — required by Saudi Arabia. Influenza vaccine recommended. Yellow fever certificate if required. Carry adequate supply of chronic disease medications. NPHCDA issues health requirements annually for intending pilgrims

Traveller's diarrhoea prevention and treatment

Prevention: 'Boil it, cook it, peel it, or forget it'. Drink bottled or boiled water. Avoid ice cubes, raw salads, and street food in high-risk countries. Treatment: oral rehydration salts for hydration. Azithromycin 500 mg daily for 3 days for moderate/severe traveller's diarrhoea in adults. Ciprofloxacin is an alternative but resistance is increasing

Altitude sickness prevention

Ascend gradually — no more than 300–500 m per day above 3000 m. Stay hydrated. Avoid alcohol. Acetazolamide (Diamox) 125–250 mg twice daily starting 1–2 days before ascent — reduces AMS risk. Descend immediately if symptoms worsen or are severe

DVT prevention on long flights

Compression stockings (graduated compression, Class 1). Aisle seat — allows walking every 1–2 hours. Calf exercises while seated. Hydration — avoid alcohol and caffeine. For high-risk passengers (previous DVT, recent surgery) — discuss low-molecular-weight heparin with your doctor

Travel insurance — essential

Nigerian state insurance does not cover medical care abroad. A single hospital admission in the UK, USA, or Middle East can cost tens of thousands of dollars — beyond the means of most Nigerians. Comprehensive travel insurance covering medical evacuation is essential. Policy must cover pre-existing conditions if relevant

Medications to carry when travelling

Adequate supply of ALL regular medications (at least double the expected supply in case of delays). Malaria treatment: artemether-lumefantrine (in case prophylaxis fails or for acute illness while abroad). Oral rehydration salts. Paracetamol and ibuprofen. Antihistamine (cetirizine). Sunscreen SPF 50+. Insect repellent (DEET ≥20%). Medical alert card or letter from your doctor for controlled substances

Frequently Asked Questions

Do I need malaria prophylaxis when visiting other parts of Nigeria from Lagos?

If you have lived in Lagos all your life and visit another malaria-endemic Nigerian state, your existing partial immunity is adequate — malaria prophylaxis within Nigeria is not routinely recommended for adult Nigerians. However, young children, pregnant women, and immunocompromised individuals should consider prophylaxis. Malaria tablets are for Nigerians visiting low-malaria or malaria-free countries, then returning to a malaria zone.

Is the yellow fever certificate issued in Nigeria accepted internationally?

Yes — certificates from NAFDAC-approved centres are valid internationally. Ensure the certificate is stamped and signed by a certified vaccinator. The international certificate is valid for life (changed from 10 years in 2016). Photo of the original certificate on your phone as backup is wise.

What vaccines do I need for a UK/USA/Europe trip?

Yellow fever vaccine is required for Nigerians by some countries (they consider Nigeria endemic). Check the specific requirements for your destination country. Recommended (not mandatory): influenza, updated COVID-19 boosters. No specific vaccines are required for travel from Nigeria to most Western countries beyond routine vaccinations. The travel clinic will advise.

Can I drink tap water in Europe?

In most Western Europe countries (UK, France, Germany, Netherlands, Scandinavia), tap water is safe and of high quality. In some Eastern European countries and rural areas, bottled water is advisable. Check WHO travel health data for your specific destination. As a Nigerian traveller, you may be unaccustomed to different gut bacteria in local water — stick to bottled water for the first few days even in 'safe' destinations if your gut is sensitive.
