This report presents results of a meeting of international experts assessing the impact of interactions between malaria and HIV on the health of individuals infected with both diseases. Malaria and HIV can cause illness and death particularly in pregnant women and children. Coinfection with malaria and HIV is common in areas where the two diseases are found such as sub-Saharan Africa, South-East Asia, Latin America and the Caribbean. Also certain population groups such as migrant workers and injecting drug users are at high risk for both diseases. The technical consultation included group and plenary discussions, and presentations and working papers on the following topics: (1) Epidemiological considerations of interactions between malaria and HIV, (2) Interactions in children and non-pregnant adults, (3) Interactions in pregnant women and infants, (4) Interactions between antimalarials and antiretrovirals, (5) Health systems and service delivery considerations. Conclusions emphasize the need for more research and recommendations adopted by the technical consulting meeting are included.
