“…1,13,14,19 We found, however, that persons diagnosed with AFP incurred the most expense related to their WNV disease. This is not surprising given the severity of AFP, which often results in partial paresis to extensive paralysis that is often permanent, and similar high costs found with other conditions that can cause limb paralysis such as Guillain-Barré Syndrome.…”

“…The extrapolated costs do not include costs incurred by public health or those related to mosquito control efforts, which are often 25% to 50% of the total cost during an outbreak response. 13,14 Finally, in the model we were conservative by 1) using a uniform distribution with a minimum of zero and a maximum equivalent to the proportion of cases in the long-term followup cohort who experienced any long-term costs to approximate the proportion of hospitalized cases in the United States who would incur long-term cost, and 2) selecting distributions from those short listed by @Risk for the Monte Carlo model that fit the data but had higher probability of picking lower costs than higher costs for the same Kolmogorov-Smirnov and Anderson-Darling goodness-of-fit.…”

“…1,13 Two previous studies have estimated the total cost of WNV disease outbreaks. 13,14 Zohrabian and others 14 focused on neuroinvasive disease cases during the early outbreak of WNV disease in Louisiana during 2002. They estimated an average cost per case of approximately $27,000.…”

“…1,[10][11][12] Despite the large number of cases over the last 14 years, only two studies have estimated the initial cost of WNV disease. 13,14 There are no published data on the economic burden of the specific clinical syndromes seen with WNV infections or the longer term costs of WNV disease incurred several years after the initial illness. We present data on both initial hospital costs and 5 years of follow-up care costs for persons hospitalized with different clinical presentations of WNV disease.…”

Abstract. There are no published data on the economic burden for specific West Nile virus (WNV) clinical syndromes (i.e., fever, meningitis, encephalitis, and acute flaccid paralysis [AFP]). We estimated initial hospital and lost-productivity costs from 80 patients hospitalized with WNV disease in Colorado during 2003; 38 of these patients were followed for 5 years to determine long-term medical and lost-productivity costs. Initial costs were highest for patients with AFP (median $25,117; range $5,385-$283,381) and encephalitis (median $20,105; range $3,965-$324,167). Long-term costs were highest for patients with AFP (median $22,628; range $624-$439,945) and meningitis (median $10,556; range $0-$260,748). Extrapolating from this small cohort to national surveillance data, we estimated the total cumulative costs of reported WNV hospitalized cases from 1999 through 2012 to be $778 million (95% confidence interval $673 million-$1.01 billion). These estimates can be used in assessing the cost-effectiveness of interventions to prevent WNV disease.

Six Climate Change–Related Events In The United States Accounted For About $14 Billion In Lost Lives And Health Costs

et al. 2011

The future health costs associated with predicted climate change-related events such as hurricanes, heat waves, and floods are projected to be enormous. This article estimates the health costs associated with six climate change-related events that struck the United States between 2000 and 2009. The six case studies came from categories of climate change-related events projected to worsen with continued global warming-ozone pollution, heat waves, hurricanes, infectious disease outbreaks, river flooding, and wildfires. We estimate that the health costs exceeded $14 billion, with 95 percent due to the value of lives lost prematurely. Actual health care costs were an estimated $740 million. This reflects more than 760,000 encounters with the health care system. Our analysis provides scientists and policy makers with a methodology to use in estimating future health costs related to climate change and highlights the growing need for public health preparedness. C limate change endangers public health. Rising atmospheric temperatures increase the frequency, intensity, duration, and geographic extent of heat waves, air pollution episodes, wildfires, activity of infectious disease vectors, rising sea levels, storms, extreme rainfall, and flooding. 1,2Prior studies have estimated future health costs related to climate change.3-6 However, these figures are not specific enough to form the basis of health policy decisions. No US study has evaluated specific health outcomes associated with a set of events related to climate change. 7,8 There is currently no well-accepted structure for quantifying the costs of the human health effects of climate change, in part because of the challenges of identifying comprehensive health impact data and a lack of consensus on health cost valuation methods. Some methods estimate health costs in monetary terms; others use physical units such as the number of lives saved or the number of cases of illness avoided. Another approach is to use indicators such as quality-adjusted life-years, a measure that incorporates both mortality and morbidity effects. 9Estimating the health costs of climate change is important for informing health policy decisions. Evaluating health-associated costs using a common method and then aggregating the costs can allow us to compare the various effects of climate change-once normalized, to account for geographic and other differences-with regard to magnitude or importance. Case studies can also help us gauge the progress of climate change-related health preparedness policies over time under different adaptation scenarios. 9These scenarios present a range of possible regional climate effects, varying health vulnerabilities, and changing social and economic conditions that can help or hinder these policies' effectiveness.The objective of this study was to provide a cost calculation of health effects associated with events related to climate change over the past
