Karenia brevis是一种有害的海藻，几乎每年都会在佛罗里达西海岸发生。在高浓度下，K.短枝藻花可通过向大气中释放称为短枝藻毒素的强效毒素而造成危害。流行病学研究表明，雾化的短尾丝虫毒素与人类呼吸道疾病有关。我们假设K.在控制环境因素、疾病和旅游业的情况下，我们试图利用这种关系来估计与雾化短尾丝虫毒素相关的疾病的成本。我们开发了一个统计的假设响应模型来表达呼吸系统疾病和水华事件之间的关系。我们用艾德就诊的数据估计了模型，K。brevis细胞密度，以及花粉、污染物、呼吸道疾病和年内种群变化的测量。我们发现滞后K。短细胞计数、低气温、流感爆发、高花粉计数和游客访问有助于解释特定医院艾德诊断的数量。与K相关的艾德呼吸系统疾病的资本化估计边际疾病成本。仅在佛罗里达萨拉索塔县，根据水华的严重程度，开花K。brevis导致重大的经济影响。艾德就诊的疾病成本是对总经济影响的保守估计。了解与K有关的经济损失的规模将变得越来越有必要。brevis blooms对适当的缓解措施做出理性的选择。
Algal blooms of Karenia brevis, a harmful marine algae, occur almost annually off the west coast of Florida. At high concentrations, K. brevis blooms can cause harm through the release of potent toxins, known as brevetoxins, to the atmosphere. Epidemiologic studies suggest that aerosolized brevetoxins are linked to respiratory illnesses in humans. We hypothesized a relationship between K. brevis blooms and respiratory illness visits to hospital emergency departments (EDs) while controlling for environmental factors, disease, and tourism. We sought to use this relationship to estimate the costs of illness associated with aerosolized brevetoxins. We developed a statistical exposure–response model to express hypotheses about the relationship between respiratory illnesses and bloom events. We estimated the model with data on ED visits, K. brevis cell densities, and measures of pollen, pollutants, respiratory disease, and intra-annual population changes. We found that lagged K. brevis cell counts, low air temperatures, influenza outbreaks, high pollen counts, and tourist visits helped explain the number of respiratory-specific ED diagnoses. The capitalized estimated marginal costs of illness for ED respiratory illnesses associated with K. brevis blooms in Sarasota County, Florida, alone ranged from $0.5 to $4 million, depending on bloom severity. Blooms of K. brevis lead to significant economic impacts. The costs of illness of ED visits are a conservative estimate of the total economic impacts. It will become increasingly necessary to understand the scale of the economic losses associated with K. brevis blooms to make rational choices about appropriate mitigation.
