“Test and Treat” Model Offers New Strategy for Eliminating MalariaPosted: February 6, 2012
The study was conducted in southern Zambia, with colleagues from the Johns Hopkins Malaria Research Institute in Macha. Researchers analyzed data from surveys conducted in 2007 and between 2008 and 2009. In both surveys, households were screened for malaria using rapid diagnostic tests and treated with artemisinin combination therapy when malaria was detected.According to the new study, a proactive test-and-treat case-detection strategy resulted in a sixfold reduction in prevalence in 2008 and 2009, with the initial parasite prevalence at 4 percent. Test and treat showed a twofold reduction in 2007, when community prevalence was higher at 24 percent.
