Rift Valley Fever: An Economic Assessment of Agricultural and Human Vulnerability

Abstract

This research focused on the assessment of the U.S. agricultural sector and human vulnerability to a Rift Valley Fever (RVF) outbreak and the implications of a select set of alternative disease control strategies. Livestock impact assessment is done by using an integrated epidemic/economic model to examine the extent of RVF spread in the Southeast Texas livestock population and its consequences plus the outcome of implementing two different control strategies: emergency vaccination and larvicide vector control separately plus when they are used simultaneously. Human impact assessment utilized an inferential procedure, which comprises of a cost of illness calculation to assess the dollar cost of human illnesses and deaths, as well as a Disability Adjusted Life Year calculation to give an estimate of the burden of disease on public health as a whole. Results indicate substantial potential losses to the U.S., where combined livestock and human national costs ranged from $121 million to$2.3 billion.Rift Valley Fever, Outbreak, Welfare, Vaccination, Larvicide., Environmental Economics and Policy, Food Consumption/Nutrition/Food Safety, Food Security and Poverty, Health Economics and Policy,
