🦟 What is Malaria?

Malaria is a life-threatening disease caused by Plasmodium parasites, transmitted through the bites of infected female Anopheles mosquitoes. It is preventable and curable — but still kills hundreds of thousands each year.

There are 5 species of Plasmodium. P. falciparum is the most deadly and most common in Sub-Saharan Africa including Nigeria.

  • P. falciparum — Most dangerous, dominant in Africa
  • P. vivax — Common in Asia & Latin America
  • P. malariae — Mild but chronic
  • P. ovale — Rare, West Africa
  • P. knowlesi — Zoonotic, Southeast Asia
💡 Nigeria accounts for roughly 27% of global malaria cases — the highest of any country.

🌡️ How Climate Change Drives Malaria Risk

Climate change alters temperature, rainfall patterns, and humidity — the exact conditions that determine where and when mosquitoes thrive.

  • Higher temperatures speed up parasite development inside mosquitoes
  • More rainfall creates standing water — ideal mosquito breeding grounds
  • Extended rainy seasons prolong peak transmission windows
  • Altitude expansion — mosquitoes now survive in highlands once too cold
  • Displacement — climate-driven flooding forces people into endemic zones
⚠️ By 2050, climate change could expose an additional 2.4 billion people to malaria risk — WHO.
🌡️ At 25°C, Anopheles mosquitoes breed 30% faster than at 20°C. Every degree of warming matters.

🌿 Mosquito Habitats & Climate

Anopheles mosquitoes need warm temperatures (above 16°C), standing fresh water, and high humidity. Breeding sites include:

  • Stagnant ponds, puddles, and flooded fields
  • Blocked drainage channels in urban areas
  • Construction site water storage
  • Water pots, tyres, and open containers
  • River banks during and after flooding
🗺️ In Nigeria, peak breeding occurs April–October in the South and June–September in the North — periods getting longer with climate change.

🤒 Malaria Symptoms

Symptoms appear 10–15 days after an infected bite. Early recognition saves lives.

  • 🌡️ High fever & chills (cyclical every 48–72 hrs)
  • 🤕 Severe headache
  • 😓 Sweating and fatigue
  • 🤢 Nausea and vomiting
  • 💪 Muscle & joint pain
  • 🩺 Pale skin (anaemia)
  • 🧠 Confusion or seizures (severe cases)
🚨 Severe malaria is a medical emergency. If fever is cyclical or confusion develops — go to hospital immediately.

70% of malaria deaths happen in children under 5.

🔄 How Malaria is Transmitted

  • 1. Infected mosquito bites human → injects sporozoites
  • 2. Parasites travel to the liver, multiply silently
  • 3. Parasites enter bloodstream, infect red blood cells
  • 4. Red blood cells burst → fever cycles begin
  • 5. Another mosquito bites infected person → picks up parasites
  • 6. Cycle continues
🌙 Anopheles mosquitoes are most active dusk to dawn — your highest-risk window.

🛡️ Prevention Strategies

  • 🛏️ Insecticide-Treated Nets (ITNs) — sleep under one every night
  • 🏠 Indoor Residual Spraying (IRS)
  • 💊 Chemoprevention for pregnant women & children
  • 🚫 Drain standing water — drain, cover, clear
  • 🧴 Repellents — DEET-based on exposed skin
  • 👕 Protective clothing — long sleeves at dusk/dawn
  • 💉 Vaccination — RTS,S/AS01 (Mosquirix)
  • 🏥 Rapid Diagnosis & Treatment — test early, treat with ACTs
✅ In Nigeria, free ITNs and malaria testing are available at government health centres.

Question 1 of 10Score: 0
🚨 HIGH RISK — Active Transmission Season
June 2026 — South-West Nigeria
Nigeria is currently in peak rainy season (April–October). Heavy rainfall across Lagos, Ibadan, Benin City, Port Harcourt, and surrounding states has created widespread breeding conditions. Take all precautions now.
⚠️ ELEVATED — North-Central Belt
June 2026 — Abuja, Benue, Niger States
The north-central region is entering peak transmission. Rainfall increasing and standing water accumulating around urban zones in Abuja. Risk is rising.
✅ MODERATE — Northern States
June 2026 — Kano, Sokoto, Zamfara
Risk currently moderate in far northern states. Rainy season peaks here July–September. Begin precautionary measures now.

Prevention Tips

🛏️
Sleep Under a Net
Use insecticide-treated bed nets every night. Anopheles peak activity is 10pm–4am.
💧
Drain Standing Water
Empty buckets, tyres, pots and clear gutters after every rainfall.
🌬️
Use Fans & Screens
Mosquitoes are weak fliers. Window screens and fans reduce landing.
🧴
Apply Repellent
Use DEET or picaridin-based repellent on exposed skin at dusk and dawn.
🏥
Test Before You Treat
Get a free RDT within 24hrs of fever. Do not self-medicate.
🤰
Pregnant? Extra Care
Take IPTp-SP at every antenatal visit. Malaria in pregnancy is deadly.
🧒
Children Under 5
Most at risk. Seek care at the first sign of fever. Free tests at PHCs.
👕
Cover Up at Dusk
Long-sleeved shirts and trousers from 6pm reduce bite exposure significantly.

ℹ️ What does your zone mean?
🔴 High Risk

Sleep under ITN every night. Drain standing water. Visit PHC immediately if fever develops.

🟡 Elevated

Use bed nets and repellent. Monitor for symptoms. Risk is rising — take precautions now.

🟢 Moderate

Standard precautions apply. Rainy season approaching — prepare your nets and drainage.
