OBJECTIVE
The objective of this study was to investigate a large outbreak of shigellosis in Papua New Guinea that began in a camp for internally displaced persons before spreading throughout the general community.
METHODS
Outbreak mitigation strategies were implemented in the affected area to curtail the spread of the disease. Data were collected from the surveillance system and analysed by time, place and person. Rectal swab samples were tested by standard culture methods and real-time polymerase chain reaction to determine the etiology of the outbreak.
RESULTS
Laboratory analysis at two independent institutions established that the outbreak was caused by Shigella sp., with one strain further characterized as Shigella flexneri serotype 2. Approximately 1200 suspected cases of shigellosis were reported in a two-month period from two townships in Morobe Province, Papua New Guinea. The outbreak resulted in at least five deaths, all in young children.
DISCUSSION
This outbreak of shigellosis highlights the threat of enteric diseases to vulnerable populations such as internally displaced persons in Papua New Guinea, as has been observed in other global settings.
目的
本研究的目的是调查巴布亚新几内亚发生的一起大规模志贺氏菌病暴发，该疫情始于一个境内流离失所者营地，随后蔓延至整个社区。
方法
在受影响地区实施了疫情缓解策略，以遏制疾病传播。从监测系统收集数据，并按时间、地点和人员进行分析。通过标准培养方法和实时聚合酶链反应对直肠拭子样本进行检测，以确定疫情的病因。
结果
两个独立机构的实验室分析确定，此次疫情由志贺氏菌属引起，其中一个菌株进一步鉴定为福氏志贺氏菌2型。在巴布亚新几内亚莫罗贝省的两个城镇，两个月内报告了约1200例疑似志贺氏菌病病例。此次疫情导致至少5人死亡，均为幼儿。
讨论
正如在其他全球环境中所观察到的那样，此次志贺氏菌病暴发凸显了肠道疾病对巴布亚新几内亚境内流离失所者等弱势群体的威胁。
