为了确定赞比亚1型志贺氏菌(SD1)引起的疫情的传播方式，进行了一项病例对照研究。病例-患者更有可能最近接触过痢疾患者(P=.03)，并且有一位有过痢疾病史的家庭成员(P=.01)。病例家庭更有可能共用厕所(P=0.06)。储存的饮用水是通过用手将杯子浸入宽口容器或从窄口容器倒出获得的；病例家庭更有可能只通过手蘸水获得饮用水(P=0.03)。病例-患者更有可能吃过从小贩那里购买的调味品(熟肉或蔬菜；P=0.03)。这项研究的证据表明，SD1是通过人与人之间的传播、通过储存在允许手工浸泡的容器中的水以及通过小贩出售的预制食品传播的。预防措施应针对这些危险因素。
To determine the modes of transmission of an epidemic caused by Shigella dysenteriae type 1 (Sd1) in Zambia, a case-control study was conducted. Case-patients were more likely to have recent contact with a person with dysentery (P = .03) and to have a family member with preceding dysentery (P = .01). Case households were more likely to share their latrine (P = .06). Stored drinking water was obtained by hand-dipping a cup into wide-mouthed vessels or by pouring from narrow-mouthed vessels; case households were more likely to obtain drinking water only by hand-dipping (P = .03). Case-patients were more likely to have eaten relish (a cooked meat or vegetable dish; P = .03) purchased from a vendor. Evidence from this study suggests that Sd1 was transmitted by person-to-person spread, by water stored in vessels that permitted hand-dipping, and by prepared foods sold by vendors. Preventive measures should be directed at these risk factors.
