Podcast 519: Malaria Drug Resistance 

Contributor: John Winkler

Educational Pearls:

  • There is increasing resistance to antimalarial drugs, especially in P. falciparum. This trend started with chloroquine, but is now spreading to the other first-line drugs. 
  • Resistant strains have been identified in Cambodia and Thailand
  • 220 million people were infected last year
  • The best treatment of malaria is prevention from bites – DEET and permethrin are typical effective options.
  • Permethrin may be applied to clothing items before travel, and will last through 6-8 wash cycles.
  • While malaria is rare in the US, it should be considered in those having recently travelled
