In recent years there has been a dramatic increase in treatment demand for abuse of drugs including methamphetamine (MA) in the Western Cape Province (WCP) of South Africa. MA use has been linked to risky sexual behaviour and sexually transmitted infections including HIV. Thus, MA use has immense public health implications. It is against this background that a model was formulated to study the dynamics of treatment use for MA abuse in the WCP, with the aim of providing a predictive tool for the prevalence of drug use. The results of this study are presented in this article.
In the October 2, 2009 issue of PloS Computational Biology, a paper was published describing a model estimating the impact of both insecticide-treated bednets (ITN’s) and new fungal biopesticides on the transmission rates and hence prevalence of malaria. These two interventions affect mosquitoes at different ages and stages in their lifecycle. The model demonstrates that Read More
