1. Key Ideas

Malaria kills a child every two minutes. Not because we lack the knowledge to prevent it — we have bed nets, insecticides, antimalarial drugs, and a working vaccine. It persists because of poverty, geography, and the relentless pressure of natural selection on both the parasite and the mosquito.

  • The causative agents, vectors, and transmission of malaria and dengue
  • How the Plasmodium life cycle creates multiple intervention points

2. Success Criteria

By the end, you should be able to:

  • The causative agents, vectors, and transmission of malaria and dengue
  • The global distribution and burden of each disease
  • The main control strategies used for each disease
