Abstract
Over the past 5 years, we have witnessed remarkable progress in malaria control. In Africa, the approach has been to “scale up for impact”1 by rapidly deploying insecticide-treated nets and providing artemisinin-based combination therapy. Programs in Equatorial Guinea, Ethiopia, Rwanda, Zambia, and Zanzibar have shown that when coverage of these interventions exceeds 50 to 60% of the population, the prevalence of infection with malaria parasites and mortality among children from such infection falls by 20 to 25% within 12 to 36 months.2
