Conquering the intolerable burden of malaria: what's new, what's needed

This article introduces a special collection of contributions by malaria researchers from around the world, including some information first presented at a symposium in Tanzania in 2002. The article is a useful overview of malaria's global impact and our current understanding of mosquito ecology and parasite transmission. It describes new measures needed to combat and eventually eliminate malaria. The full supplement — freely available online, in print or on DVD — features articles on how well artemisinin combination therapies treat malaria and delay the emergence of drug-resistant parasites, how useful insecticide-treated bed nets are, and progress towards a vaccine. It also covers social and economic dimensions of malaria, and how they affect the scaling up and use of existing prevention and control measures.
