Malaria is making a dramatic comeback in the world. The disease is the foremost health challenge in Africa south of the Sahara, and people traveling to malarious areas are at increased risk of malaria-related sickness and death. This book examines the prospects for bringing malaria under control, with specific recommendations for U.S. policy, directions for research and program funding, and appropriate roles for federal and international agencies and the medical and public health communities. The volume reports on the current status of malaria research, prevention, and control efforts worldwide. The authors present study results and commentary on the Nature, clinical manifestations, diagnosis, and epidemiology of malaria. This book talks about: biology of the malaria parasite and its vector; prospects for developing malaria vaccines and improved treatments; and economic, social, and behavioral factors in malaria control.
