Evaluating the potential for the environmentally sustainable control of foot and mouth disease in Sub-Saharan Africa
Strategies to control transboundary diseases have in the past generated unintended negative consequences for both the environment and local human populations. Integrating perspectives from across disciplines, including livestock, veterinary and conservation sectors, is necessary for identifying disease control strategies that optimise environmental goods and services at the wildlife-livestock interface. Prompted by the recent development of a global strategy for the control and elimination of foot-and-mouth disease (FMD), this paper seeks insight into the consequences of, and rational options for potential FMD control measures in relation to environmental, conservation and human poverty considerations in Africa. We suggest a more environmentally nuanced process of FMD control that safe-guards the integrity of wild populations and the ecosystem dynamics on which human livelihoods depend while simultaneously improving socio-economic conditions of rural people. In particular, we outline five major issues that need to be considered: 1) improved understanding of the different FMD viral strains and how they circulate between domestic and wildlife populations; 2) an appreciation for the economic value of wildlife for many African countries whose presence might preclude the country from ever achieving an FMD-free status; 3) exploring ways in which livestock production can be improved without compromising wildlife such as implementing commodity-based trading schemes; 4) introducing a participatory approach involving local farmers and the national veterinary services in the control of FMD; and 5) finally the possibility that transfrontier conservation might offer new hope of integrating decision-making at the wildlife-livestock interface

Susceptibility of Non-target Aquatic Macro-invertebrates and Vertebrates to Piper guineense (Piperaceae) and Spilanthes mauritiana (Asteraceae) Powder in Kilifi District, Kenya
Powders of Piper guineense and Spilanthes mauritiana, potential mosquito larvicides, were assessed to determine their impact on non-target aquatic macro-invertebrates and vertebrates. Field tests were conducted in Kilifi District, Kenya on field populations of damselfly nymph (Gomphilidae), dragonfly nymph (Coenagrionidae), macro-dytiscids, micro-dytiscids (Dystiscidae), notonectids (Notonectidae), freshwater shrimps (Palaemonidae), tadpoles (Ranidae) and tilapia fish (Cichlidae). Artifical habitats were sampled and populations determined before and after application of the plant powder. Four doses (8.571, 5.714, 2.875 and 1.429 g L super(-1)), were used in the trials and mortalities monitored after 24, 48 and 72 h. After 24 h, at 1.429 g L super(-1) of the powder from P. guineense and S. mauritiana, less than 20% mortality was obtained against gomphilids, coenagrionids, dytiscids, notonectids and palaemonids. At 48 h, powder of P. guineense gave 8.8 and 45% mortality against micro-dytiscids and tadpoles at 8.571 g L super(-1), respectively. After 72 h, at 2.847 g L super(-1), powder of S. mauritiana caused 6.9 and 35% mortality against micro-dytiscids and fish, respectively. The LD sub(50)s (24 h) for the organisms varied from 12.2 to 39.2 g L super(-1) and 13.6 to 41.82 g L super(-1) for P. guineense and S. mauritiana, respectively. Both plant powders showed slight negative effects on non-target aquatic macro-invertebrates and vertebrates

Evidence of injection drug use in Kisumu, Kenya: Implications for HIV prevention.
BackgroundInjection drug use is increasingly contributing to the HIV epidemic across sub-Saharan Africa. This paper provides the first descriptive analysis of injection drug use in western Kenya, where HIV prevalence is already highest in the nation at 15.1%.MethodsWe draw on quantitative data from a study of injection drug use in Kisumu, Kenya. We generated descriptive statistics on socio-demographics, sexual characteristics, and drug-related behaviors. Logistic regression models were adjusted for sex to identify correlates of self-reported HIV positive status.ResultsOf 151 participants, mean age was 28.8 years, 84% (n = 127) were male, and overall self-reported HIV prevalence reached 19.4%. Women had greater than four times the odds of being HIV positive relative to men (Odds Ratio [OR] 4.5, CI: 1.7, 11.8, p = .003). Controlling for sex, ever experiencing STI symptoms (Adjusted Odds ratio [AOR] 4.6, 95% CI 1.7, 12.0, p = .002) and sharing needles or syringes due to lack of access (AOR 3.6, 95% CI 1.2, 10.5, p = .02) were significantly associated with HIV positive status. Lower education (AOR 2.3, 95% CI 0.9, 5.6, p=.08), trading sex for drugs (AOR 2.8, 95% CI 0.9, 8.8, p = .08), being injected by a peddler (AOR 2.9, 95% CI 1.0, 8.5, p = .05), and injecting heroin (AOR 2.3, 95% CI 1.0, 5.7, p = .06), were marginally associated with HIV.ConclusionsThis exploratory study identified patterns of unsafe drug injection and concurrent sexual risk in western Kenya, yet few resources are currently available to address addiction or injection-related harm. Expanded research, surveillance, and gender sensitive programming are needed
