Malaria Prevention in Nigeria — 2026 Guide
Nigeria carries the highest malaria burden in the world, accounting for roughly 27% of all global malaria cases. Every traveller to Nigeria must take malaria prevention seriously — antimalarials, repellents, and nets are essential, not optional.
Critical Warning: Malaria is present throughout Nigeria year-round, in every state. There are no malaria-free zones. All travellers must take prophylactic antimalarials.
Malaria Risk by Region
Nigeria is classified as a high-transmission country by the World Health Organization. Unlike some African nations with mixed-risk zones, every region of Nigeria carries significant malaria risk.
| Region | Risk Level | Peak Season | Notes |
|---|---|---|---|
| Lagos & South-West | Very High | Apr – Oct | Coastal humidity creates ideal breeding grounds; year-round transmission |
| South-South (Niger Delta) | Very High | Year-round | Swampy terrain, highest rainfall; malaria endemic all 12 months |
| South-East (Enugu, Imo) | Very High | Apr – Oct | Tropical climate with consistent transmission |
| North-Central (Abuja, Jos) | High | Jun – Oct | Rainy season peak; Jos Plateau slightly lower risk due to altitude (~1,200m) |
| North-West (Kano, Kaduna) | High | Jun – Oct | Seasonal transmission during rains; dry season risk still present |
| North-East (Maiduguri, Borno) | High | Jun – Oct | Semi-arid but rainy season brings heavy transmission |
Key fact: Nigeria records approximately 68 million confirmed malaria cases and over 190,000 deaths annually (WHO 2024 World Malaria Report). Plasmodium falciparum accounts for 99.7% of infections — the most dangerous species.
Antimalarial Medication Comparison
All travellers to Nigeria should take prophylactic antimalarials. Consult your GP or travel clinic at least 4–6 weeks before departure.
| Medication | Dosing | Start | Continue After Return | UK Cost (approx.) | US Cost (approx.) | Common Side Effects |
|---|---|---|---|---|---|---|
| Malarone (Atovaquone/Proguanil) |
1 tablet daily | 1–2 days before | 7 days | £40–£80 (2 weeks) | $60–$150 (2 weeks) | Nausea, headache, abdominal pain (generally mild) |
| Doxycycline | 100mg daily | 1–2 days before | 28 days | £5–£15 (4 weeks) | $10–$30 (4 weeks) | Sun sensitivity, stomach upset, thrush (take with food) |
| Mefloquine (Lariam) |
1 tablet weekly | 2–3 weeks before | 4 weeks | £15–£30 (4 weeks) | $40–$80 (4 weeks) | Vivid dreams, dizziness, anxiety (screen for psychiatric history) |
Recommendation for Nigeria: Malarone or Doxycycline are the most commonly prescribed for Nigeria. Malarone has fewer side effects but costs more. Doxycycline is the budget-friendly choice. Mefloquine suits long-term travellers due to weekly dosing but must be trialled before travel due to possible neuropsychiatric side effects.
Prevention Methods
1. Insect Repellent (DEET-based)
- Use repellents containing 30–50% DEET on all exposed skin
- Recommended brands: Jungle Formula Maximum (UK), OFF! Deep Woods (US), Repel 100
- Reapply every 4–6 hours, more often if swimming or sweating
- Alternative: Picaridin 20% (Saltidin) if DEET causes skin irritation
2. Mosquito Nets
- Sleep under a permethrin-treated insecticide-treated net (ITN) every night
- Check for holes before use; tuck edges under the mattress
- Hotels in Lagos and Abuja often provide nets — confirm when booking
3. Protective Clothing
- Wear long sleeves and trousers from dusk to dawn (peak biting hours for Anopheles mosquitoes)
- Light-coloured clothing is less attractive to mosquitoes
- Treat clothing with permethrin spray for extra protection
4. Environmental Measures
- Keep windows and doors closed or screened after dark
- Use air conditioning where available — mosquitoes avoid cool, dry rooms
- Avoid standing water near your accommodation
- Use plug-in mosquito vaporisers (available in Nigerian supermarkets)
Recognising Malaria Symptoms
Malaria symptoms can appear 7 days to 1 year after being bitten. Most commonly symptoms develop within 10–28 days. P. falciparum (the species in Nigeria) can progress to severe, life-threatening illness within 24–48 hours.
Early Symptoms
- High fever (38°C+) with chills and sweating
- Severe headache
- Muscle and joint aches
- Nausea, vomiting, diarrhoea
- Extreme fatigue
Danger Signs (Seek Emergency Care)
- Confusion or altered consciousness
- Seizures
- Difficulty breathing
- Dark or bloody urine
- Jaundice (yellowing of eyes/skin)
- Inability to keep fluids down
Important: If you develop a fever during or after travel to Nigeria — even up to 12 months later — tell your doctor you visited a malaria-endemic country. A simple blood test (thick and thin film) confirms diagnosis.
Emergency Treatment in Nigeria
If you suspect malaria while in Nigeria:
- Get tested immediately — Rapid Diagnostic Tests (RDTs) are available at pharmacies for ₦500–₦2,000 (~$0.60–$2.50)
- Seek hospital treatment — Do not self-treat with local antimalarials
- Artemisinin-based Combination Therapy (ACT) is the standard treatment in Nigeria, typically Artemether-Lumefantrine (Coartem)
- Severe malaria requires intravenous artesunate in a hospital setting

Children & Pregnant Women
Children
- Children under 5 are at the highest risk of severe malaria — they account for 80% of malaria deaths in Nigeria
- Malarone is approved for children weighing ≥5kg; paediatric tablets available
- Doxycycline is not suitable for children under 12
- Mefloquine can be used from 5kg body weight (quarter tablet dosing)
- Use DEET repellent at 20–30% concentration for children (avoid hands and face in infants)
Pregnant Women
- The UK and US governments advise against non-essential travel to Nigeria during pregnancy due to malaria risk
- Malaria in pregnancy increases risk of miscarriage, premature birth, and low birth weight
- Mefloquine is the only antimalarial licensed for all trimesters of pregnancy
- Malarone lacks sufficient safety data for pregnancy
- Doxycycline is contraindicated in pregnancy
