Background Forcibly Displaced Myanmar Nationals (FDMNs) fled into Cox’s Bazar, Bangladesh due to internal conflict. Considering the public health situation, a surveillance network was established to identify the enteric pathogens and early detection of cholera epidemics. The purpose of this manuscript is to report the clinical, epidemiological determinants of cholera and other enteric pathogens among hospitalized diarrheal patients from FDMNs and host community. Methods A total of 11 sentinel surveillance sites were established around the camps in Ukhia and Teknaf Upazila, Cox’s Bazar. Rapid diagnostic testing was conducted for immediate detection of cholera cases. Stool samples were transferred to the Infectious Diseases Division, International Centre for Diarrhoeal Disease Research Bangladesh (icddr,b) laboratory for culture. Results A total of 8134 participants with diarrhea were enrolled from 2017 to 2019: 4881 were FDMNs and 3253 were from the Bangladeshi host community. Among the FDMNs, the proportion of Vibrio cholerae was 0.7%, the proportion of enterotoxigenic Escherichia coli (ETEC) was 4.9%, and the proportion of Shigella was 1.5%. The distributions from host community were 1.2% V cholerae, 1.8% ETEC, and 1.1% Shigella. Similar risk factors have been identified for the diarrheal pathogens for both communities. Conclusions This surveillance helped to monitor the situation of diarrheal diseases including cholera in refugee camps as well as in the neighboring host community. These findings lead policymakers to take immediate preventive measures.

孟加拉国考克斯巴扎尔 2017-2019 年罗兴亚危机期间的急性水样腹泻监测

背景 由于内部冲突，被迫流离失所的缅甸国民 (FDMNs) 逃到了孟加拉国的考克斯巴扎尔。考虑到公共卫生状况，建立了监测网络，以识别肠道病原体和早期发现霍乱流行病。本手稿的目的是报告来自 FDMN 和宿主社区的住院腹泻患者中霍乱和其他肠道病原体的临床、流行病学决定因素。方法 在科克斯巴扎尔的乌奇亚和泰克纳夫乌帕齐拉营地周围共建立了 11 个哨点监视点。进行了快速诊断测试以立即发现霍乱病例。粪便样本被转移到孟加拉国国际腹泻病研究中心 (icddr,b) 实验室传染病科进行培养。结果 2017 年至 2019 年共有 8134 名腹泻参与者入组：4881 人为 FDMN，3253 人来自孟加拉国收容社区。FDMNs中，霍乱弧菌占0.7%，产肠毒素大肠杆菌(ETEC)占4.9%，志贺氏菌占1.5%。来自宿主社区的分布是 1.2% V cholerae、1.8% ETEC 和 1.1% Shigella。对于两个社区的腹泻病原体，已经确定了类似的风险因素。结论 这种监测有助于监测难民营和邻近收容社区的腹泻病情况，包括霍乱。这些发现促使政策制定者立即采取预防措施。4881 人是 FDMN，3253 人来自孟加拉国东道社区。FDMNs中，霍乱弧菌占0.7%，产肠毒素大肠杆菌(ETEC)占4.9%，志贺氏菌占1.5%。来自宿主社区的分布是 1.2% V cholerae、1.8% ETEC 和 1.1% Shigella。对于两个社区的腹泻病原体，已经确定了类似的风险因素。结论 这种监测有助于监测难民营和邻近收容社区的腹泻病情况，包括霍乱。这些发现促使政策制定者立即采取预防措施。4881 人是 FDMN，3253 人来自孟加拉国东道社区。FDMNs中，霍乱弧菌占0.7%，产肠毒素大肠杆菌(ETEC)占4.9%，志贺氏菌占1.5%。来自宿主社区的分布是 1.2% V cholerae、1.8% ETEC 和 1.1% Shigella。对于两个社区的腹泻病原体，已经确定了类似的风险因素。结论 这种监测有助于监测难民营和邻近收容社区的腹泻病情况，包括霍乱。这些发现促使政策制定者立即采取预防措施。来自宿主社区的分布是 1.2% V cholerae、1.8% ETEC 和 1.1% Shigella。对于两个社区的腹泻病原体，已经确定了类似的风险因素。结论 这种监测有助于监测难民营和邻近收容社区的腹泻病情况，包括霍乱。这些发现促使政策制定者立即采取预防措施。来自宿主社区的分布是 1.2% V cholerae、1.8% ETEC 和 1.1% Shigella。对于两个社区的腹泻病原体，已经确定了类似的风险因素。结论 这种监测有助于监测难民营和邻近收容社区的腹泻病情况，包括霍乱。这些发现促使政策制定者立即采取预防措施。
