European travelers in Africa in the mid-19th century encountered environments quite unlike those of their native lands. These provided many new and unanticipated health challenges. The ophthalmological consequences of exposure to such climates, as recorded incidentally in travelogues, are of potential interest. In this article, the almost contemporaneous narratives of 3 travelers with considera...
In the mid 1990s, the HIV epidemic was initially impacting South Africa. Fear, stigma and denial surrounding sexual practices undermined treatment access and prevention initiatives. Significant strides have been made in reducing the HIV epidemic in South Africa and other areas in sub-Saharan Africa through effective programming and funding of prevention programs. Reinstatement of the Mexico Cit...
Sub-Saharan Africa has the highest number of mother to child transmissions of HIV. PMTCT programme plays a big role in reducing the MTCT nevertheless its effectiveness in sub-Saharan Africa depends on involvement of male partners considering the fact that men are decision makers in African families. They make important decisions that have big impact on women’s health. Male partner involvement h...
Drosophila melanogaster is an important model organism in evolutionary genetics, yet little is known about the population structure and the demographic history of this species within sub-Saharan Africa, which is thought to contain its ancestral range. We surveyed nucleotide variation at four 1-kb fragments in 240 individual lines representing 21 sub-Saharan and 4 Palearctic population samples o...
BACKGROUND Many studies have investigated the migration intentions of sub-Saharan African medical students and health professionals within the context of a legacy of active international recruitment by receiving countries. However, many health workers migrate outside of this recruitment paradigm. This paper aims to explore the reasons for migration of health workers from sub-Saharan Africa to B...
BACKGROUND Globally, the population of adolescents living with perinatally acquired HIV (APHs) continues to expand. In this study, we pooled data from observational pediatric HIV cohorts and cohort networks, allowing comparisons of adolescents with perinatally acquired HIV in "real-life" settings across multiple regions. We describe the geographic and temporal characteristics and mortality outc...
Schistosomiasis, a neglected tropical disease of poverty ranks second among the most widespread parasitic disease in various nations in sub-Saharan Africa. Neglected tropical diseases are causes of about 534,000 deaths annually in sub-Saharan Africa and an estimated 57 million disability-adjusted life-years are lost annually due to the neglected tropical diseases. The neglected tropical disease...
PREMISE OF THE STUDY Our goal was to infer the phylogenetic relationships and historical biogeography of the genus Dryopteris with a focus on taxa in sub-Saharan Africa and neighboring islands. In general, little is known about the relationships between African fern species and their congeners in other geographic regions, and our aim was to determine whether the sub-Saharan African species of D...
SETTING There is a high burden of respiratory disease in sub-Saharan Africa. To address this problem, the World Health Organization launched the 'Practical approach to Lung Health' (PAL), i.e., locally applicable integrated syndromic algorithms, to improve primary care management of these diseases. OBJECTIVE To examine the evidence for the impact of PAL on the diagnosis and management of tube...
Sub-Saharan Africa suffers an inordinate burden of disease and does not have the numbers of suitably trained health care workers to address this challenge. New concepts in health sciences education are needed to offer alternatives to current training approaches.A perspective of integrated training in population health for undergraduate medical and nursing education is advanced, rather than cont...
