The epidemiology of infectious diseases in Japan remains undefined despite the increasing tourism. GeoSentinel, an epidemiological surveillance system for reporting imported infectious diseases, has only two participating facilities in Japan. Although the number of infectious diseases is reported by the National Institute of Infectious Diseases, there is no detailed clinical information about these cases. Therefore, we established J-RIDA (Japan Registry for Infectious Diseases from Abroad) to clarify the status of imported infectious diseases in Japan and provide detailed information.
J-RIDA was started as a registry of imported infectious diseases. Case registration began in October 2017. Between October 2017 and September 2019, 15 medical institutions participated in this clinical study. The registry collected information about the patient's age, sex, nationality, chief complaint, consultation date, date of onset, whether visit was made to a travel clinic before travel, blood test results (if samples were collected), travel history, and final diagnosis.
Of the 3046 cases included in this study, 46.7% to Southeast Asia, 13.0% to Africa, 13.7% to East Asia, 11.5% to South Asia, 7.5% to Europe, 3.8% to Central and South America, 4.6% to North America, 3.9% to Oceania, and 2.8% to Central and west Asia. More than 85% of chief complaints were fever and general symptoms, gastrointestinal symptoms, respiratory symptoms, or dermatologic problems. The most common diseases were travelers' diarrhea, animal bite, upper respiratory infection, influenza, and dengue fever.
We summarized two-year cases registered in Japan's imported infectious disease registry. These results will significantly contribute to the epidemiology in Japan.
尽管日本的旅游业不断发展，但日本传染病的流行病学情况仍未得到明确界定。GeoSentinel 是一个报告输入性传染病的流行病学监测系统，在日本仅有两家参与机构。尽管日本国立传染病研究所报告了传染病的数量，但这些病例没有详细的临床信息。因此，我们设立了 J-RIDA（日本国外传染病登记处），以明确日本输入性传染病的现状并提供详细信息。
J-RIDA 是一个输入性传染病登记处。病例登记于 2017 年 10 月开始。在 2017 年 10 月至 2019 年 9 月期间，有 15 家医疗机构参与了这项临床研究。该登记处收集了患者年龄、性别、国籍、主诉、就诊日期、发病日期、旅行前是否前往旅行诊所就诊、血液检查结果（如有采集样本）、旅行史和最终诊断等信息。
在这项研究中，纳入了 3046 例病例，其中 46.7%前往东南亚，13.0%前往非洲，13.7%前往东亚，11.5%前往南亚，7.5%前往欧洲，3.8%前往中南美洲，4.6%前往北美洲，3.9%前往大洋洲，2.8%前往中西亚。超过 85%的主诉是发热和全身症状、胃肠道症状、呼吸道症状或皮肤病问题。最常见的疾病是旅行者腹泻、动物咬伤、上呼吸道感染、流感和登革热。
我们总结了日本输入性传染病登记处登记的两年病例。这些结果将对日本的流行病学产生重大影响。
