How to Prevent Malaria: A Comprehensive Guide for African Families

Malaria continues to be one of Africa’s most significant public health challenges. In 2023, the WHO estimated that over 90% of global malaria cases and deaths occurred in the African region. Children under five and pregnant women face the greatest risk. Yet malaria is both preventable and treatable. This guide outlines practical, evidence-based strategies that African families can adopt to protect themselves.

Understanding How Malaria Spreads

Malaria is caused by Plasmodium parasites transmitted to humans through the bites of infected female Anopheles mosquitoes. These mosquitoes are most active between dusk and dawn and breed in standing water. Understanding the mosquito’s behaviour is the first step in effective prevention.

1. Use Insecticide-Treated Mosquito Nets (ITNs)

Sleeping under an insecticide-treated net (ITN) — also known as a long-lasting insecticidal net (LLIN) — is the single most effective personal protection measure against malaria. Research shows that widespread use of LLINs can reduce malaria cases by up to 50% in endemic areas.

• Ensure the net covers the entire sleeping area and is tucked under the mattress
• Check nets regularly for holes and repair or replace damaged nets promptly
• Use nets every night, not only when mosquitoes are visibly present
• Prioritise nets for children under five and pregnant women if supply is limited

2. Indoor Residual Spraying (IRS)

Indoor residual spraying involves applying insecticides to the walls and ceilings of homes, where mosquitoes rest after feeding. IRS is typically carried out by national malaria control programmes. If your community is scheduled for IRS, cooperate fully by moving furniture and covering food before the spray team arrives.

3. Eliminate Mosquito Breeding Sites

Anopheles mosquitoes breed in standing water. Reducing breeding sites around your home is a highly effective community-level intervention:

• Empty, invert, or cover water storage containers, buckets, and tyres
• Clear blocked gutters and drainage channels regularly
• Fill in puddles and low-lying areas where water collects after rain
• Keep compound areas clean and free of debris that can hold water

4. Use Repellents and Protective Clothing

When spending time outdoors in the evening or early morning, protect your skin:

• Apply insect repellents containing DEET (20–30%) or picaridin to exposed skin
• Wear long-sleeved shirts and long trousers, preferably in light colours
• Install wire mesh screens on windows and doors to keep mosquitoes out

5. The RTS,S/AS01 Malaria Vaccine

A significant breakthrough in malaria prevention arrived with the approval and rollout of the RTS,S/AS01 vaccine (Mosquirix) for children in sub-Saharan Africa. This vaccine, which targets Plasmodium falciparum — the deadliest malaria parasite — has been shown to significantly reduce severe malaria cases in children. Several countries including Ghana, Kenya, Malawi, and Nigeria are rolling it out as part of national immunisation programmes. If your child is eligible, speak to your healthcare provider about vaccination.

6. Chemoprevention for High-Risk Groups

For those at highest risk, preventive medication is available:

• Intermittent preventive treatment in pregnancy (IPTp) — Pregnant women in endemic areas are recommended to receive sulfadoxine-pyrimethamine at each antenatal visit after the first trimester
• Seasonal malaria chemoprevention (SMC) — In the Sahel region of West Africa, children under five receive preventive antimalarial medicine during the high-transmission season

Recognising Malaria Symptoms

Act quickly if you or a family member develops symptoms — early treatment saves lives. Malaria typically presents with:

• High fever (often recurring in cycles)
• Chills and shivering
• Headache and muscle aches
• Fatigue and weakness
• Nausea and vomiting

If these symptoms appear, seek medical care immediately. Do not self-treat without a confirmed diagnosis. Rapid diagnostic tests (RDTs) are available at most health facilities and provide results within minutes.

What to Do While Waiting for Medical Care

If you are in a remote area and access to care is delayed: keep the patient cool and hydrated, monitor their condition closely, and seek the nearest health facility as quickly as possible. Severe malaria — characterised by convulsions, loss of consciousness, difficulty breathing, or extreme weakness — is a medical emergency.
