Vulnerability for the Hazards of the Environment - Essay Example

           The study by Rabinowitz et al. (2005) offers a systematic review of the literature of animal sentinel to identify evidence that relates such events to the health of human beings. A weakness of this study was that it could not assess the factors causing the failure of the animal sentinel studies to use cohort and case-control methods more. Such approaches prove time-consuming and expensive compared to such other methods as the aggregate and cross-sectional study designs. Funding limitations may possibly have influenced the choices of study methods of animal sentinel. Another weakness of this study is that its small sample size affects its capacity to offer valid evidence. The strength of this study is that the authors have suggested a set of linkage points that are helpful for the assessment of evidence to bridge an event of animal sentinel to human health. The research recognized gaps in the existing knowledge like shared outcomes, inadequate shared exposures’ documentation, and the relative vulnerability between humans and animals for the hazards of the environment.
