Qu'est-ce que Malaria?

Malaria is caused by Plasmodium parasites transmitted through bites of infected Anopheles mosquitoes. In 2022, there were an estimated 249 million cases and 608,000 deaths globally. Despite being preventable and treatable, malaria continues to devastate communities, particularly affecting children under 5 and pregnant women in Africa.

SymptĂ´mes

  • High fever and chills (often in cycles)
  • Severe sweating
  • Headache and body aches
  • Nausea and vomiting
  • Fatigue and weakness
  • Anemia (severe cases)
  • Jaundice (yellowing of skin and eyes)
  • Confusion or seizures (cerebral malaria)

Transmission

Malaria is transmitted primarily through bites from infected female Anopheles mosquitoes. These mosquitoes typically bite between dusk and dawn. Transmission can also occur through blood transfusions, organ transplants, shared needles, or from mother to unborn child.

Période de Contagiosité : Not directly contagious person-to-person; infectious to mosquitoes when parasites are present in blood (varies by species and treatment)

Prévention

  • Take antimalarial medications when traveling to endemic areas (chemoprophylaxis)
  • Sleep under insecticide-treated bed nets
  • Use insect repellent containing DEET on exposed skin
  • Wear long-sleeved clothing, especially after sunset
  • Use indoor residual spraying with insecticides
  • Eliminate standing water breeding sites
  • Consider malaria vaccine in high-risk areas (children)
  • Stay in air-conditioned or well-screened rooms

How climate change is reshaping Africa's malaria risk

Researchers say warming temperatures are altering malaria transmission patterns across Africa, creating new challenges for health systems and disease control.

For decades, global efforts towards the eradication of malaria, especially in sub-Saharan Africa, have focused essentially on West and Central Africa where the disease is most endemic.

The WHO African Region accounts for about 95% of global malaria cases and deaths. More than half of all malaria deaths in the region occur in Nigeria (31.9

Global health leaders urge stronger procurement support for made-in-Nigeria diagnostics

Nigeria 2026-07-04

International development organisations have called for stronger government commitment, catalytic procurement policies and predictable market demand to accelerate Nigeria's local diagnostics manufacturing industry.

Scientists say climate change is changing where malaria spreads across Africa, with South Africa's north-eastern provinces projected to experience some of the continent's biggest increases in climate-driven risk Climate change is reshaping Africa's malaria map, increasing the risk of the disease in South Africa's north-eastern provinces and the East African highlands even as warming temperatures make some of the continent's current malaria hotspots less suitable for transmission, according to a landmark study published in Nature. The international study, co-authored by researchers from the University of Cape Town (UCT), is the most comprehensive assessment to date of how human-caused climate change has influenced childhood malaria across sub-Saharan Africa, where most global malaria cases ...
