Despite the endemic nature of Entamoeba histolytica infection in the United States there is a lack of data on amebiasis-related mortality. We analyzed national death certificate data from 1990 to 2007 to assess the occurrence of amebiasis-related deaths and determine demographic and regional associations. A total of 134 deaths were identified. Mortality rates were highest in males, Hispanics, Asian/Pacific Islanders, and persons 75 years of age and older. An association with human immunodeficiency virus infection was also observed. A declining trend of amebiasis deaths was noted over the 18-year study period. Over 40% of fatal amebiasis cases occurred in residents of California and Texas. United States-born persons accounted for the majority of amebiasis deaths; however, all of the fatalities in Asian/Pacific Islanders and 60% of the deaths in Hispanics were in foreign-born individuals. Although uncommon, amebiasis-related deaths routinely occur in the United States.
尽管溶组织内阿米巴在美国呈地方性流行，但有关阿米巴病相关死亡率的数据却很少。我们分析了 1990 年至 2007 年的全国死亡证明数据，以评估与阿米巴病相关的死亡发生情况，并确定人口统计学和地区相关性。共确定了 134 例死亡。男性、西班牙裔、亚洲/太平洋岛民以及 75 岁及以上的人群死亡率最高。还观察到与人类免疫缺陷病毒感染有关。在 18 年的研究期间，阿米巴病死亡人数呈下降趋势。超过 40%的致命性阿米巴病病例发生在加利福尼亚州和得克萨斯州的居民中。土生土长的美国人占阿米巴病死亡人数的绝大多数；然而，所有在亚洲/太平洋岛民中的死亡病例和在西班牙裔中的 60%的死亡病例都是在外国出生的人。尽管阿米巴病并不常见，但它在美国仍会导致死亡。
