Recent evidence suggests that, in some foci, elimination of onchocerciasis from Africa may be feasible with mass drug administration (MDA) of ivermectin. To achieve continental elimination of transmission, mapping surveys will need to be conducted across all implementation units (IUs) for which endemicity status is currently unknown. Using boosted regression tree models with optimised hyperparameter selection, we estimated environmental suitability for onchocerciasis at the 5 × 5-km resolution across Africa. In order to classify IUs that include locations that are environmentally suitable, we used receiver operating characteristic (ROC) analysis to identify an optimal threshold for suitability concordant with locations where …

Background: Preterm birth continues to be a major public health problem contributing to 75% of the neonatal mortality worldwide. Low birth weight (LBW) is an important but imperfect surrogate for prematurity when accurate assessment of gestational age is not possible. While there is overlap between preterm birth and LBW newborns, those that are both premature and LBW are at the highest risk of adverse neonatal outcomes. Understanding the epidemiology of preterm birth and LBW is important for prevention and improved care for at risk newborns, but in many countries, data are sparse and incomplete.
Methods: We conducted data analyses using …

Among more than 2500 nontyphoidal Salmonella enterica (NTS) serovars, S. enterica serovar Typhimurium and S. enterica serovar Enteritidis account for approximately fifty percent of all human isolates of NTS reported globally. The global incidence of NTS gastroenteritis in 2010 was estimated to be 93 million cases, approximately 80 million of which were contracted via food-borne transmission. It is estimated that 155,000 deaths resulted from NTS in 2010. NTS also causes severe, extra-intestinal, invasive bacteremia, referred to as invasive nontyphoidal Salmonella (iNTS) disease. iNTS disease usually presents as a febrile illness, frequently without gastrointestinal symptoms, in both adults and children. Symptoms …


Concurrent Sexual And Substance-Use Risk Behaviours Among Female Sex Workers In Kenya's Coast Province: Findings From A Behavioural Monitoring Survey, Simon Pierre Tegang, S. Abdallah, G. Emukule, Stanley Luchters, Nzioka Kingola, M. Barasa, Stephen Mucheke, P. Mwarogo Dec 2010

While many studies confirm the association between HIV, alcohol and injecting drug use by female sex workers (FSWs), little is known about their use of marijuana, khat and other substances and the association of these substances with HIV, risky sexual behaviour, and sexual violence. To better understand this association, data were analysed from a cross-sectional, behavioural survey of 297 FSWs in Mombasa, a well-known tourist destination and the second largest port in Africa and capital city of the Coast Province in Kenya. Among the FSWs, lifetime use of different substances was reported by 91% for alcohol, 71% for khat, 34% …
