资源匮乏社区对疾病的了解有限，这继续阻碍着健康状况的改善。我们评估了家庭坑式厕所采样作为一种非侵入性的方法来调查重要的粪便病原体，如贾第鞭毛虫和隐孢子虫属。在贫困社区，寻求健康的行为限制了基于卫生机构的监测的敏感性。在同一时期，从随机选择的家庭的坑式厕所和该地区唯一一家医院的病人中收集粪便样本。用市售ELISA检测样品。2016年贾第虫家庭患病率为28.7%，2017年为48.4%，而2016年和2017年医院提交的个体样本贾第虫患病率分别为2.4%和8.0%。隐孢子虫只在一户人家发现。结果表明，坑厕监测粪便传播的感染提供了社区感染水平的估计，是公正的寻求健康的行为，并允许监测人口中的弱势群体。
Limited understanding of disease in low resource communities continues to hamper improvements in health. We evaluated household pit latrine sampling as a non-invasive approach to investigate important fecal pathogens such as Giardia lamblia and Cryptosporidium spp. in impoverished communities where health-seeking behavior limits the sensitivity of health facility-based surveillance. Fecal samples were collected from pit latrines in randomly selected households and from patients presenting to the only hospital in the region during the same time periods. Samples were tested with a commercially available ELISA. Giardia household prevalence was 28.7% in 2016 and 48.4% in 2017, while individual samples from hospital submission had a Giardia prevalence of 2.4% in 2016 and 8.0% in 2017. Cryptosporidium was only found in one household. Results suggest that pit latrine surveillance for fecal-borne infections provide course estimates of community infection levels that are unbiased by health seeking behaviors and allow surveillance of vulnerable sectors of a population.
