Amebiasis is one of the most common parasite-related diseases and one of those with the greatest impact on health. At the Instituto Mexicano del Seguro Social (Mexican Institute of Social Security-IMSS) approximately half a million cases per year are currently treated. Of these, more than 2500 correspond to the form which invades the liver. Within the process of epidemiologic transition which Mexico is undergoing, a progressive reduction has been observed in incidence of, and mortality due to, invading amebiasis in all its clinical forms. In turn, there is a significant decrease in its fatality rate. The social and economic development and improved sanitary conditions observed in Mexico, particularly in the second half of this century, may have conditioned this process. The improvement in availability, accessibility and utilization of medical care services could also explain the reduction which has been noted in its fatality rate and mortality. The model for epidemiologic transition proposed by Omran and adapted for Mexico by Frenk, offers a plausible explanation for the changes observed in the occurrence and mortality of invading amebiasis in Mexico.
阿米巴病是最常见的寄生虫相关疾病之一，也是对健康影响最大的疾病之一。目前，墨西哥社会保障局（IMSS）每年治疗约50万例病例。其中，超过2500例为侵袭肝脏的类型。在墨西哥正在经历的流行病学转变过程中，侵袭性阿米巴病所有临床类型的发病率和死亡率都在逐渐下降。相应地，其病死率也显著降低。墨西哥观察到的社会和经济发展以及卫生条件改善，尤其是在本世纪下半叶，可能促成了这一过程。医疗服务的可及性、可获得性和利用率的提高也可以解释病死率和死亡率的下降。Omran提出并由Frenk为墨西哥改编的流行病学转变模型，为墨西哥侵袭性阿米巴病的发病情况和死亡率变化提供了合理的解释。
