"Significant investment in malaria research has yielded effective interventions such as insecticide treated nets (ITNs), indoor residual spraying (IRS) and artemisinin-based combination therapies (ACTs) to control the disease, but its burden continues to be felt among the poorest," George Okello, a research fellow at the Kenya Medical Research Institute, and Nina Cromeyer Dieke, communications manager for the Global Atlas of Helminth Infections based at the London School of Hygiene & Tropical Medicine, write in an opinion piece in the Guardian's "Global Development Professionals Network." "The disease still kills over half a million people a year, the majority of them young African children who are unable to afford or access prevention methods," they note.
