Nets and New Drug Make Inroads Against Malaria

The report was one of the most hopeful signs in the long battle against a disease that is estimated to kill a million children a year in poor tropical countries.

“We saw a very drastic impact,” said Dr. Arata Kochi, chief of malaria for the W.H.O. “If this is done everywhere, we can reduce the disease burden 80 to 85 percent in most African countries within five years.”

There have been earlier reports of success with nets and the new medicine, artemisinin, a Chinese drug made from wormwood. But most have been based on relatively small samples; this is the first study to compare national programs.

“This is extremely exciting,” said Dr. Michel Kazatchkine, executive director of the Global Fund to Fight AIDS, Tuberculosis and Malaria. “If we can scale up like this everywhere, we should be able to eliminate malaria as a major public health threat in many countries.”
