The U.S. government announced on Thursday it would focus part of its $63 billion, six-year Global Health Initiative plan to accelerate efforts to fight malaria, mostly in Africa and aimed at women and children.

The goal is to reach 450 million people, or about 70 percent of the highest-risk populations in sub-Saharan Africa. The plan is to use insecticide-treated nets, indoor insecticide spraying, preventive treatment of pregnant women, and treatment of infected people with artemisinin-based drug cocktails.
