The presence of anti-HCV antibodies was investigated in sera from a total of 123 inhabitants of two Tanzanian villages. In one of the villages, 72.2% of the sera and in the other village, 82.6% of the sera were found to be anti-HCV positive. These values are dramatically higher than other reported prevalences, whereby cross-reactivity between HCV and Flaviviruses as well as possible transmission by arthropod vectors cannot be ruled out.

Background: Malaria-endemic countries are increasingly adopting data-driven risk stratification, often at district or higher regional levels, to guide their intervention strategies. The data typically comes from population-level surveys collected by rapid diagnostic tests (RDTs), which unfortunately perform poorly in low transmission settings. Here, a high-resolution survey of Plasmodium falciparum prevalence rate (PfPR) was conducted in two Tanzanian districts using rapid diagnostic tests (RDTs), microscopy, and quantitative polymerase chain reaction (qPCR) assays, enabling the comparison of fine-scale strata derived from these different diagnostic methods.

Article Synopsis
- The study investigates the link between Onchocerca volvulus (causing onchocerciasis) and epilepsy in Mahenge, Tanzania, focusing on the prevalence of both conditions after 25 years of ivermectin treatment.
- A cross-sectional survey of 56,604 individuals was conducted, revealing onchocerciasis prevalence among children at 11.8%, higher in medium-altitude villages, and epilepsy incidence at 21.1 cases per 1,000 persons, also more prevalent in medium altitudes.
- Female gender, middle altitudes, and positive OV16 antibodies were associated with a higher likelihood of having epilepsy, highlighting ongoing public health challenges despite long-term ivermectin use.

The use of medicinal plants in traditional healing practices is essential to Tanzanian and African health care. This paper examined the African traditional healing tendencies, particularly the Sukuma tribe of Tanzania, from 1922 to the 1960s. Several types of research challenged traditional healing tendencies' role in the health sector.

Background: Schistosomiasis is a parasitic disease which is spread through skin contact with water containing Schistosoma cercariae. Drug treatment has been the main control method, but it does not prevent reinfection. The use of soap can be a complementary measure to reduce transmission.

This pilot study aimed to estimate the community-based prevalence of MSK disorders, identify predictors, and assess the associated disability in a Tanzanian population.
Methods: a cross-sectional study was conducted in one village in the Kilimanjaro region from March to June 2019.
