Quality assurance of rapid diagnostic tests for malaria in routine patient care in rural Tanzania (Publications)
Histidine-rich protein II (HRP2)-based malaria rapid diagnostic tests (RDTs) have shown high sensitivity and specificity for detecting Plasmodium falciparum malaria in a variety of study settings. However [...] their use in field settings. We evaluated sensitivity and specificity of RDTs during routine use for malaria case management in peripheral health facilities. From December 2007 to October 2008, HRP2-based ParaHIT-f [...] thick blood smear. Job aids, Integrated Management of Childhood...

We assessed health worker malaria treatment practices after [...] received training on how to perform RDTs for patients 5 years of age or older with fever or suspected malaria. Children < 5 years of age were to be treated empirically per national guidelines. Among the 30,195 [...] 195 patients seen at these 12 health facilities, 10,737 (35.6%) were...

The primary end point of the analysis was vaccine efficacy against clinical malaria during the 12 months after vaccination in the [...] vaccine according to protocol. After 250 children had an episode of severe malaria, we evaluated vaccine efficacy against severe malaria in both age categories. Results In the 14 months after the first dose [...] against severe malaria was 45.1% (95% CI, 23.8 to 60.5) in the...
