Journal ArticleDOI
Detection of Plasmodium falciparum by Light Microscopy, Loop-Mediated Isothermal Amplification, and Polymerase Chain Reaction on Day 3 after Initiation of Artemether-Lumefantrine Treatment for Uncomplicated Malaria in Bagamoyo District, Tanzania: A Comparative Trial.
Lwidiko E. Mhamilawa,Lwidiko E. Mhamilawa,Berit Aydin-Schmidt,Bruno P. Mmbando,Billy Ngasala,Billy Ngasala,Ulrika Morris +6 more
TL;DR: Loop-mediated isothermal amplification had comparable diagnostic accuracy to PCR and could potentially represent a field-friendly tool for determining day 3 positivity rates, however, what day 3 P. falciparum positivity determined using molecular methods represents needs to be further elucidated.
Journal ArticleDOI
Socio-demographic determinants of dengue infection during an outbreak in Dar es Salaam City, Tanzania
Neema Camara,Billy Ngasala,Germana H Leyna,Ahmed Abade,Susan F. Rumisha,Ndekya M. Oriyo,Leonard E. G. Mboera +6 more
TL;DR: Dengue infection in Dar es Salaam varied between the three districts and was associated with being employed, having piped water at home and a recent visit to the health facility, which may be used to develop appropriate preventive interventions.
Journal ArticleDOI
The usefulness of indirect diagnostic tests for Schistosoma haematobium infection after repeated rounds of mass treatment with praziquantel in Mpwapwa and Chakechake districts in Tanzania.
TL;DR: It is suggested that that urine reagent strips will continue to serve as very useful adjunct tests for monitoring prevalence of urinary schistosomiasis in endemic areas.
Journal ArticleDOI

TL;DR: A systematic review and individual patient data (IPD) meta-analysis of single-dose (SD) primaquine studies for P. falciparum malaria were performed as mentioned in this paper .
Journal ArticleDOI

TL;DR: In this paper , the authors used hierarchical logistic regression models to evaluate associations between land cover and malaria prevalence within three distinct strata of transmission intensity: low and unstable, moderate and seasonal, and high and perennial.
