为了估计被动病例检测低估危地马拉皮肤利什曼病真实发病率的程度，我们将危地马拉卫生部被动监测系统的数据与危地马拉皮肤利什曼病横断面人群调查进行了比较。在接受访谈的2，938人中，143人（5%）报告在过去某个时候患有皮肤利什曼病，37人（1.3%）报告在调查前12个月内开始感染，31人（1.1%）有活动性感染，16人（0.5%）有寄生虫学证实的感染。根据这些报告和流行地区的估计人口计算，在调查前12个月里，利什曼病流行地区的新病例总数约为2，574例;在同一12个月期间，卫生部根据被动监测的数据列出了64例皮肤利什曼病。在危地马拉，基于被动监测的发病率估计数可能低估了皮肤利什曼病的发病率，低估率高达40倍。
To estimate the degree to which passive case detection underestimates the true incidence of cutaneous leishmaniasis in Guatemala, we compared data from the passive surveillance system of the Guatemalan Ministry of Health with a cross-sectional population-based survey of cutaneous leishmaniasis in Guatemala. Of the 2,938 persons interviewed, 143 (5%) reported having had cutaneous leishmaniasis at some time in the past, 37 (1.3%) reported the onset of infection in the 12 months before the survey, 31 (1.1%) had active infections and 16 (0.5%) had parasitologically confirmed infection. Calculated on the basis of these reports and the estimated population of the endemic area, the total number of new cases in the leishmaniasis-endemic area in the 12 months before the survey was .apprx.2,574; during the same 12 month period, Ministry of Health data based on passive surveillance listed 64 cases of cutaneous leishmaniasis. In Guatemala, incidence estimates based on passive surveillance may underestimate the occurrence of cutaneous leishmaniasis by as much as a factor of 40.
