Malaria control in an urban area: a success story from Khartoum, 1995-2004

Khartoum is an urban area with low malaria transmission. Early control efforts were successful in reducing the risk but malaria has resurged in recent years. In 2002, the Government of Sudan, with support of the World Health Organization, embarked on an initiative aimed at freeing Khartoum of malaria. The initiative's prevention strategy has focused on larval control interventions. The results indicate a significant reduction in malaria prevalence, confirmed and clinically diagnosed malaria cases among outpatient attendance and the number of malaria-associated deaths. It is proposed information be collected on parity rates and that a sub-sample of the adult mosquito collections be subjected to ELISA or PCR for identification of malaria parasite infections in mosquitoes in areas showing active foci.
