What is 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.
Symptoms
- 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.
Contagious Period: Not directly contagious person-to-person; infectious to mosquitoes when parasites are present in blood (varies by species and treatment)
Prevention
- 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
