In 2013, an unusual increase of paratyphoid fever cases in travellers returning from Cambodia was reported in Japan. From December 2012 to September 2013, 18 cases of Salmonella Paratyphi A infection were identified. Microbiological analyses revealed that most isolates had the same clonal identity, although the epidemiological link between these cases remains unclear. It was inferred that the outbreak was caused by a common and persistent source in Cambodia that was likely to have continued during 2014. The information of surveillance and laboratory data from cases arising in travellers from countries with limited surveillance systems should be timely shared with the country of origin.
2013年，日本报告称从柬埔寨回国的旅行者中副伤寒热病例异常增加。2012年12月至2013年9月，共确诊18例甲型副伤寒沙门氏菌感染病例。微生物学分析显示，尽管这些病例之间的流行病学联系尚不清楚，但大多数分离株具有相同的克隆特征。据推测，此次疫情是由柬埔寨一个常见且持续存在的传染源引起的，该传染源在2014年可能仍在持续。对于来自监测系统有限国家的旅行者所出现病例的监测信息和实验室数据，应及时与原籍国共享。
