Why is sexual violence more pervasive in the Eastern Cape Province of South Africa than in the Northern Cape Province? Most research surrounding sexual violence in South Africa attempts to answer why rape happens, but doesn’t attempt to understand why individuals choose to report sexual violence crimes to police. This paper looks at three variables—chieftaincy and regional identity, physical sp...

Little is known about the history of click-speaking populations in Africa. Prior genetic studies revealed that the click-speaking Hadza of eastern Africa are as distantly related to click speakers of southern Africa as are most other African populations. The Sandawe, who currently live within 150 km of the Hadza, are the only other population in eastern Africa whose language has been classified...

Several outbreaks of Rift Valley fever (RVF) have been documented in South Africa since it first occurred in the country in 1950. However, there is no comprehensive account of the timing, location and extent of all known outbreaks. As part of a study investigating the epidemiology of RVF in South Africa, a full history of outbreaks was compiled using references to the disease in South Africa fr...

BACKGROUND Subtype A accounts for only 12% of HIV-1 infections worldwide but predominates in Russia and Former Soviet Union countries of Eastern Europe. After an early propagation via heterosexual contacts, this variant spread explosively among intravenous drug users. A distinct A1 variant predominates in Greece and Albania, which penetrated directly from Africa. Clade A1 accounts for 12.5% of ...

BACKGROUND There is strong evidence showing that voluntary medical male circumcision (VMMC) reduces HIV incidence in men. To inform the VMMC policies and goals of 13 priority countries in eastern and southern Africa, we estimate the impact and cost of scaling up adult VMMC using updated, country-specific data. METHODS AND FINDINGS We use the Decision Makers' Program Planning Tool (DMPPT) to m...

Scientists widely agree that species extinction has heavily accelerated in the last decades. A grave problem for the conservation of diversity is the still very fragmentary knowledge of the ecology of most species. Attempts of sustainable management and conservation must integrate local communities and their traditional knowledge. Management decisions need to include the high importance of natu...

To elucidate whether Rift Valley fever virus (RVFV) diversity in Sudan resulted from multiple introductions or from acquired changes over time from 1 introduction event, we generated complete genome sequences from RVFV strains detected during the 2007 and 2010 outbreaks. Phylogenetic analyses of small, medium, and large RNA segment sequences indicated several genetic RVFV variants were circulat...

Eastern and Southern Africa has a significant number of major transport corridors that provide trade and mobility for coastal and landlocked countries. In 2008 PPIAF funded the Definition and Investment Strategy for a Core Strategic Transport Network for Eastern and Southern Africa, which examines strategic core transportation networks in the region. The study‟s objective was to diagnose the pr...

[1] New estimates of seismic anisotropy from shear wave splitting measurements in eastern Africa reveal a pattern of seismic anisotropy dominated by a NE alignment of fast polarization directions with local changes around the thick Archean lithosphere of the Tanzania craton. The overall pattern is consistent with mantle flow from the African superplume but not with absolute plate motion, a plum...

BACKGROUND Rift Valley fever (RVF) outbreaks have been associated with periods of widespread and above-normal rainfall over several months. Knowledge on the environmental factors influencing disease transmission dynamics has provided the basis for developing models to predict RVF outbreaks in Africa. From 2008 to 2011, South Africa experienced the worst wave of RVF outbreaks in almost 40 years....
