Seven years of regional malaria control collaboration--Mozambique, South Africa, and Swaziland.

The Lubombo Spatial Development Initiative is a joint development program between the governments of Mozambique, Swaziland, and South Africa, which includes malaria control as a core component of the initiative. Vector control through indoor residual spraying (IRS) was incrementally introduced in southern Mozambique between November 2000 and February 2004. Surveillance to monitor its impact was conducted by annual cross-sectional surveys to assess the prevalence of Plasmodium falciparum infection, entomologic monitoring, and malaria case notification in neighboring South Africa and Swaziland.
