A teenage girl from Saitama Prefecture has been confirmed positive for the mosquito borne virus, dengue fever. The case is being called an autochthonous, or locally acquired case, the first such case seen in Japan in more than 60 years.
Japan Today reports, Government spokesman Yoshihide Suga, in confirming the report, said Wednesday that the news was not cause for alarm because the illness is not transmitted directly from person to person.
Japan sees scores of imported dengue cases annually from travelers to endemic areas. In 2013, they reported 249 cases.
