Peste-des-petits ruminants (PPR) is one of the most important infectious diseases of domesticated small ruminants. From the initial identification in 1942 in West Africa, PPR virus (PPRV) has spread throughout much of the developing world. PPRV is now considered endemic throughout Africa, with the notable exception of South Africa, the Middle-East and Israel, as well as South-, East-, and Central Asia. Despite this widespread dispersal, the evolution and transmission of PPRV in endemic populations is not well understood...

African tick-bite fever (ATBF), a tickborne disease endemic in rural areas of sub-Saharan Africa and the West Indies caused by Rickettsia africae, has been recognized as an emerging health problem in recent years. ATBF has been reported as the second most commonly documented etiology of fever, after malaria, in travelers who return ill from sub-Saharan Africa. Most cases reported in the literature occurred in middle-aged adults, so the incidence of ATBF in children is unclear. We report a cluster of three cases of ATBF that occurred in children ages 7 to 16 years after returning from a game-hunting safari in South Africa...

BACKGROUND: Studies describing the epidemiology of influenza B lineages in South Africa are lacking. METHODS: We conducted a prospective study to describe the circulation of influenza B/Victoria and B/Yamagata lineages among patients of all ages enrolled in South Africa through three respiratory illness surveillance systems between 2005 and 2014: (i) the Viral Watch (VW) program enrolled outpatients with influenza-like illness (ILI) from private healthcare facilities during 2005-2014; (ii) the influenza-like illnesses program enrolled outpatients in public healthcare clinics (ILI/PHC) during 2012-2014; and (iii) the severe acute respiratory illnesses (SARI) program enrolled inpatients from public hospitals during 2009-2014...

INTRODUCTION: Improved HIV outcomes as a result of expanded antiretroviral therapy (ART) access is threatened by increasing rates of loss to follow up (LTFU) among those on ART, largely reported in urban populations. Some reports suggest that LTFU rates are overestimated due to patient movement to other facilities and inadequate medical records. STUDY OBJECTIVE: To define the proportion disengaging from HIV care as well as the characteristics of those LTFU in order to design and implement appropriate interventions to increase retention...

The critical speed (CS) concept helps characterize the aerobic and anaerobic fitness of an athlete. Rugby players should hypothetically have modest CS values but extremely high curvature constant (D') values, yet, normative data are currently unavailable. To develop normative data of CS and D' for high-level male rugby players, a total of 30 male rugby players, were recruited from the Eastern Cape of South Africa. All subjects performed the running 3-min all-out exercise test (3 MT) using global positioning system (GPS) technology to determine CS and D'...

BACKGROUND: Lack of accessible laboratory infrastructure limits HIV antiretroviral (ART) treatment initiation, monitoring and retention in many resource-limited settings. Point-of-care testing (POCT) is advocated as a mechanism to overcome these limitations. We executed a pragmatic, prospective, randomized, controlled trial comparing the impact of POCT versus standard-of-care (SOC) on treatment initiation and retention in care. METHOD: Selected POC technologies were embedded at 3 primary health clinics in South Africa...

To characterize HIV-1 transmission dynamics in regions where the burden of HIV-1 is greatest, the 'Phylogenetics and Networks for Generalised HIV Epidemics in Africa' consortium (PANGEA-HIV) is sequencing full-genome viral isolates from across sub-Saharan Africa. We report the first 3,985 PANGEA-HIV consensus sequences from four cohort sites (Rakai Community Cohort Study, n=2,833; MRC/UVRI Uganda, n=701; Mochudi Prevention Project, n=359; Africa Health Research Institute Resistance Cohort, n=92). Next-generation sequencing success rates varied: more than 80% of the viral genome from the gag to the nef genes could be determined for all sequences from South Africa, 75% of sequences from Mochudi, 60% of sequences from MRC/UVRI Uganda, and 22% of sequences from Rakai...

This study aims to determine the awareness of osteoporosis and factors that determine awareness of osteoporosis. Results showed that osteoporosis awareness was associated with age (p = 0.006) and occupation (p < 0.001) but not gender, marital status, and level of education. There is therefore need for educational interventions to improve awareness of osteoporosis.

Breast cancer is the most common cancer affecting women in South Africa. There is little knowledge of beliefs to help identify key areas to improve support and education in this demographically and culturally diverse population. Women with a variety of demographic and socioeconomic characteristics accessing care for breast cancer were asked their agreement to statements of knowledge and beliefs about breast cancer. Of the 259 participants, positive statements of medical cure (87.9%) and family support (90.5%) were most commonly believed...

INTRODUCTION: There are major differences in cancer drug prices around the world. However, the patterns of affordability of these drugs are poorly understood. The objective of this study was to compare patterns of affordability of cancer drugs in Australia, China, India, Israel, South Africa, the United Kingdom, and the United States. RESULTS: Cancer drug prices are highest in the United States. Cancer drugs are the least affordable in India by a large margin. Despite lower prices than in the USA, cancer drugs are less affordable in middle-income countries than in high-income countries...

Previous state hospital-based local studies suggest varying population-based clinicopathological patterns of colorectal cancer (CRC). Patients diagnosed with CRC in the state and private sector hospitals in Durban, South Africa over a 12-month period (January-December 2009) form the basis of our study. Of 491 patients (172 state and 319 private sector patients), 258 were men. State patients were younger than private patients. Anatomical site distribution was similar in both groups with minor variations. Stage IV disease was more common in state patients...

The detailed analysis of columnar optical and microphysical properties of aerosols obtained from the AErosol RObotic NETwork (AERONET) Cimel sun photometer operated at Skukuza (24.98° S, 31.60° E, 150 m above sea level), South Africa was carried out using the level 2.0 direct sun and inversion products measured during 1999-2010. The observed aerosol optical depth (AOD) was generally low over the region, with high values noted in late winter (August) and mid-spring (September and October) seasons. The major aerosol types found during the study period were made of 3...

BACKGROUND: The colonization of Eurasia and Australasia by African modern humans has been explained, nearly unanimously, as the result of a quick southern coastal dispersal route through the Arabian Peninsula, the Indian subcontinent, and the Indochinese Peninsula, to reach Australia around 50 kya. The phylogeny and phylogeography of the major mitochondrial DNA Eurasian haplogroups M and N have played the main role in giving molecular genetics support to that scenario. However, using the same molecular tools, a northern route across central Asia has been invoked as an alternative that is more conciliatory with the fossil record of East Asia...

Microplastics (<5 mm) were extracted from sediment cores collected in Japan, Thailand, Malaysia, and South Africa by density separation after hydrogen peroxide treatment to remove biofilms were and identified using FTIR. Carbonyl and vinyl indices were used to avoid counting biopolymers as plastics. Microplastics composed of variety of polymers, including polyethylene (PE), polypropylene (PP), polystyrene (PS), polyethyleneterphthalates (PET), polyethylene-polypropylene copolymer (PEP), and polyacrylates (PAK), were identified in the sediment...

Many invasive plants show evidence of trait-based evolutionary change, but these remain largely unexplored for invasive trees. The increasing number of invasive trees and their tremendous impacts worldwide, however, illustrates the urgent need to bridge this knowledge gap to apply efficient management. Consequently, an interdisciplinary workshop, held in 2015 at Stellenbosch University in Stellenbosch, South Africa, brought together international researchers to discuss our understanding of evolutionary dynamics in invasive trees...

INTRODUCTION: The proportion of older South African adults (aged ≥50 years old) with HIV infection requiring hospitalization is likely to increase in the near future. Clinical risk factors for in-hospital mortality (IHM) in these patients are not well described. We aimed to identify clinical risk factors associated with IHM and their overall contribution towards IHM in older South African adults with HIV infection. METHODS: Clinical data for 690 older adults with HIV infection was obtained from the hospital administrative database at the Hlabisa Hospital in KwaZulu-Natal, South Africa...

Type 2 diabetes (T2D) has attained the status of a global pandemic, spreading from affluent industrialized nations to the emerging economies of Asia, Latin America, and Africa. There is significant global variation in susceptibility to T2D, with Pacific Islanders, Asian Indians, and Native Americans being considerably more prone to develop the disorder. Although genetic factors may play a part, the rapidity with which diabetes prevalence has risen among these populations reflects the far-ranging and rapid socioeconomic changes to which they have been exposed over the past few decades...

The cultural turn in critical suicidology notes the limitations of dominant acontextual, biomedical, quantitative approaches to suicide prevention. Qualitative methods are idealized within this cultural turn as the only way to advance suicidology. Qualitative methods, however, also have limitations. Drawing on our research with traditional healers in South Africa, we explore tensions associated with making truth claims based on qualitative research. Turning the critical gaze on our work we consider the question of what we can claim to know about suicide prevention when investigating culture using qualitative methods...
