Control to elimination: implications for malaria research.

Recent reports indicate that a high level of malaria control can be achieved with existing control tools once their use has been scaled up. This has led to renewed interest in the possibility of malaria elimination, an approach that is now supported by several influential organisations. An increasing focus on elimination requires a review of priorities within the malaria research agenda. The development of drugs and vaccines with a strong transmission-blocking potential becomes increasingly important. Novel approaches to surveillance will be necessary to ensure that once elimination has been achieved, it is not threatened by a rapid reintroduction of malaria from neighbouring areas.
