SummaryBackgroundIntimate partner violence (IPV) is a significant public health issue, closely tied to social and neighborhood environments. The impoverished, overcrowded, stressful conditions in urban slums may heighten IPV risk, yet evidence remains limited. This study aims assess the prevalence, disparities, trends of across low- middle-income countries (LMICs).MethodsThis cross-sectional used nationally representative Demographic Health Surveys data from 2006 2023, focusing on with...

Abstract Background Strengthening malaria control activities in Tanzania has dramatically declined human infections. However, there is an increasing epidemiological shift the burden on school-age children. The underlying causes for such remain unknown this context. This study explored and behaviours that could increase vulnerability of children to transmission risk provide insight into protection gap with existing interventions opportunities supplementary interventions.

Abstract Background In 2015, a China-UK-Tanzania tripartite pilot project was implemented in southeastern Tanzania to explore new model for reducing malaria burden and possibly scaling-out the approach into other malaria-endemic countries. The 1,7-malaria Reactive Community-based Testing Response (1,7-mRCTR) which is locally-tailored reporting febrile cases endemic villages developed stop transmission Plasmodium life-cycle. utilizes existing health facility data locally trained community...

ABSTRACT Piperaquine tetraphosphate (PQP), a long‐acting antimalarial, is being considered in combination for chemoprevention. Dihydroartemisinin‐piperaquine tablets (hard and dispersible) approved the treatment of acute uncomplicated malaria should be administered fasted state, as PQP bioavailability increases with food. A new taste‐masked dispersible granules formulation aims to minimize impact food on drug exposure. This randomized, open label, parallel group, Phase I pilot study was...

Sub-Saharan Africa faces a disproportionate burden of HIV/AIDS, and Tanzania, reflecting this trend, challenges with only 60.6% individuals aged 15–64 aware their HIV status. Nevertheless, according to the present state affairs, mean coverage rate previous testing in Tanzania (66.5%) is still behind UNAIDS target. The 2030 target urges 95% awareness among those infected, sustained ARV therapy, viral suppression. To address this, amended its AIDS Act, permitting voluntary self-testing....

Malaria rapid diagnostic tests (mRDTs) have played an important role in the early detection of clinical malaria endemic area. While several mRDTs are currently on market, availability with high sensitivity and specificity will merit fight against malaria. We evaluated field performance a novel One Step (P.f/P.v) Tri-line (P.f) test kits Pwani, Tanzania.In cross-sectional study conducted Bagamoyo Kibiti districts Tanzania, symptomatic patients were tested using SD BIOLINE, kits, microscope,...

Introduction Insecticide-treated nets (ITNs), specifically long-lasting insecticidal (LLINs), are the most commonly used, scalable, and cost-effective tools for controlling malaria transmission in sub-Saharan Africa. However, multiple alternative uses of retired LLINs have been associated with poor disposal practices. The World Health Organization (WHO) has provided guidelines recommendations proper management worn-out LLINs. This study assessed existing practices old Methods An explanatory...

Abstract Background: Strengthening malaria control activities in Tanzania has dramatically declined human infections. However, the burden is now higher among school-age children, but with inconsistency of evidence on risk factors and underlying causes for such an epidemiological shift. This study explored behaviors that increase vulnerability children to transmission risk.

Estimating human exposure to mosquito vectors is crucial for the prediction of malaria transmission and intervention impact. The landing catch method frequently used directly measure estimate rates; however, there has been an increasing shift from this exposure-free alternatives, such as electrocuting traps (MET) other approaches. While these latter methods can provide robust representative values density, they often still require a volunteer, which poses logistical challenges. Additionally,...
