For this report, malaria and HIV/AIDS specialists were consulted on interactions between the two diseases and how having both affects people's health. They said there is still much to learn about the biological and clinical effects that malaria and HIV/AIDS have on each other. But some conclusions are already clear: integrating healthcare services is essential to reducing the burden of both diseases where they are prevalent. Health services providing HIV/AIDS prevention, treatment and care can serve as access points for malaria prevention and control. Likewise, new laboratory capacity to support HIV treatment and monitoring can also be used for malaria diagnosis. More research and debate is needed, however, before formulating new public health policies.
