Human hydatidosis in Chile is described using as a source of information the Disease Notification Systems and hospital discharges between 2001 and 2005. To assess the extent of human infection we calculated incidence rates and hospital discharges during this period by geographical region. Incidence rate for the period was 2.2 per 100,000 inhabitants with higher rates in the regions of Coquimbo, La Araucania and Magallanes. The hospital discharge rate for the period was 6 per 100.000 inhabitants, being the most affected regions: La Araucania, Aysén and Magallanes. 58.8% of cases reported are from Echinococcus granulosus, while 43.6% were registered as unspecified echinococcosis. The notification system provides a real estimate of the magnitude of this disease, reporting cases with diagnostic confirmation. The rates obtained from the discharge system overestimate the magnitude of this disease. The improvement of the notification system and seroprevalence studies are recommended.
利用疾病通报系统和2001年至2005年期间的医院出院记录作为信息来源，对智利的人类包虫病进行了描述。为评估人类感染的程度，我们按地理区域计算了该时期的发病率和医院出院率。该时期的发病率为每10万居民2.2例，在科金博、阿劳卡尼亚和麦哲伦等地区发病率较高。该时期的医院出院率为每10万居民6例，受影响最严重的地区是：阿劳卡尼亚、艾森和麦哲伦。报告的病例中有58.8%来自细粒棘球绦虫，而43.6%被登记为未明确的包虫病。通报系统提供了对该疾病规模的实际估计，报告了经诊断确认的病例。从出院系统获得的比率高估了该疾病的规模。建议改进通报系统和血清学患病率研究。
