TL;DR: Identifying risk factors for slow clearing P. falciparum infections, such as COI, are essential for ongoing surveillance of ACT treatment failure in Kenya, Tanzania, and more broadly in sub-Saharan Africa.

TL;DR: A picture of current within-country diversity of Tanzanian P. falciparum populations is provided for the first time, and Frequencies of known drug resistance mutations were higher in northern districts of the country compared to the south.
Journal ArticleDOI

Cedar L Mitchell,Billy Ngasala,Mark Janko,Frank Chacky,Jessie K. Edwards,Brian W. Pence,Ally Mohamed,Lwidiko E. Mhamilawa,Twilumba Makene,Thwai Kyaw,Fabrizio Molteni,Humphrey R. Mkali,Ssanyu Nyinondi,Bilali Kabula,Naomi Serbantez,Erin Eckert,Chonge Kitojo,Erik J. Reaves,Michael Emch,Jonathan J. Juliano +19 more
TL;DR: In this article , 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.
Journal ArticleDOI
Nutritional status of children under five years old involved in a seasonal malaria chemoprevention study in the Nanyumbu and Masasi districts in Tanzania
Bruno P. Mmbando,Richard Mwaiswelo,Frank Chacky,Fabrizio Molteni,Ally Mohamed,Samwel Lazaro,Billy Ngasala +6 more
TL;DR: Undernutrition was highly prevalent in the study population and was influenced sex, age, anaemia and malaria infection, and more emphasis is needed to address the malnutrition problem especially stunting in Masasi and Nanyumbu districts.
Posted ContentDOI
