WPSAR Vol 5, No 4, 2014 | doi: 10.5365/wpsar.2014.5.3.007 www.wpro.who.int/wpsar 1 a Infectious Disease Surveillance Center, National Institute of Infectious Diseases, Tokyo, Japan. b Department of Virology, National Institute of Infectious Diseases, Tokyo, Japan. c Department of Medical Entomology, National Institute of Infectious Diseases, Tokyo, Japan. Submitted: 26 September 2014; Published: 28 October 2014 doi: 10.5365/wpsar.2014.5.3.007 In late August 2014, three autochthonous dengue cases were reported in Japan. Since then, as of 17 September 2014, a total of 131 autochthonous cases have been confirmed. While cases were reported from throughout Japan, the majority were linked to visiting a large park or its vicinity in Tokyo, and the serotype detected has been serotype 1. We report preliminary findings, along with the public health response activities, of the first documented autochthonous dengue outbreak in Japan in nearly 70 years.

Highlights

Of dengue was during the 1940s,4 given the growing number of imported cases and the recent emergence of dengue in areas such as the United States of America,[5] France[6] and Portugal,[7] the re-emergence of dengue in Japan had been a concern in recent years
A travelassociated German case was suspected to have been infected with dengue serotype 2 while in Japan in summer 2013,8 and Japan’s MHLW and National Institute of Infectious Diseases (NIID) have since been preparing guidelines to manage response activities in case of local transmission
Physicians are required to report demographic, clinical and exposure history information of laboratory-confirmed cases to the local public health centre that are reported to the Ministry of Health, Labour and Welfare (MHLW) and the National Institute of Infectious Diseases (NIID).[1]

Introduction

Of dengue was during the 1940s,4 given the growing number of imported cases and the recent emergence of dengue in areas such as the United States of America,[5] France[6] and Portugal,[7] the re-emergence of dengue in Japan had been a concern in recent years. A travelassociated German case was suspected to have been infected with dengue serotype 2 while in Japan in summer 2013,8 and Japan’s MHLW and NIID have since been preparing guidelines to manage response activities in case of local transmission. Physicians are required to report demographic, clinical and exposure history information of laboratory-confirmed cases to the local public health centre that are reported to the Ministry of Health, Labour and Welfare (MHLW) and the National Institute of Infectious Diseases (NIID).[1]
