Hydatid disease or cystic echinococcosis, caused by the parasite Echinococcus granulosus, has a worldwide distribution, affecting people of working age and can cause high levels of morbidity and even death.
To estimate the economic impact at the human and animal level caused by the disease in Chile.
We analyzed information about the disease obtained from reports and publications emanated from the Chilean Ministry of Health, United Nations Food and Agriculture Organization, the U.S. National Institute of Statistics and the National Agricultural Service. Animal derived costs were estimated evaluating the expenses for pharmacological treatment of infected dogs and animal production losses derived from confiscations and reductions in meat production.
The total number of patients who underwent surgery to remove a hydatid cyst in Chile during 2012, was estimated as 767 individuals. The annual costs derived only from surgical treatment, were estimated in USD 2.46 million. Summing the costs of sick leaves and loss of productivity, the costs at the human level ascended to USD 3.13 million. Considering human and animal costs, the annual economic burden of the disease was estimated in USD 14.35 million.
The Analysis of the regional distribution of human and animal hydatidosis, suggests a significant environmental contamination with parasite eggs in high incidence regions such as Aysén, Araucanía, BioBío and Coquimbo. The efficiency of control programs for the disease would be greatly improved if the causes for these regional contaminations are elucidated.
包虫病或囊性棘球蚴病由寄生虫细粒棘球绦虫引起,在全球范围内均有分布,影响劳动年龄人群,可导致高发病率甚至死亡。
评估该疾病在智利对人和动物造成的经济影响。
我们分析了从智利卫生部、联合国粮食及农业组织、美国国家统计局和国家农业服务局发布的报告和出版物中获取的有关该疾病的信息。通过评估感染犬的药物治疗费用以及没收和肉类产量减少导致的动物生产损失来估算动物相关成本。
2012年在智利接受手术切除包虫囊肿的患者总数估计为767人。仅手术治疗的年度费用估计为246万美元。加上病假和生产力损失的成本,人类层面的成本升至313万美元。考虑到人和动物的成本,该疾病的年度经济负担估计为1435万美元。
对人和动物包虫病区域分布的分析表明,在艾森、阿劳卡尼亚、比奥比奥和科金博等高发病率地区,寄生虫卵对环境造成了严重污染。如果能阐明这些区域污染的原因,该疾病控制项目的效率将大大提高。
