TY - JOUR AU - Ikuno, Hiroshi AU - Akao, Shinkichi AU - Yamasaki, Hiroshi T1 - Epidemiology of Diphyllobothrium nihonkaiense Diphyllobothriasis, Japan, 2001–2016 T2 - Emerging Infectious Disease journal PY - 2018 VL - 24 IS - 8 SP - 1428 SN - 1080-6059 AB - We report 958 cases of cestodiasis occurring in Japan during 2001–2016. The predominant pathogen was Diphyllobothrium nihonkaiense tapeworm (n = 825), which caused 86.1% of all cases. The other cestode species involved were Taenia spp. (10.3%), Diplogonoporus balaenopterae (3.3%), and Spirometra spp. (0.2%). We estimated D. nihonkaiense diphyllobothriasis incidence as 52 cases/year. We observed a predominance of cases during March–July, coinciding with the cherry salmon and immature chum salmon fishing season, but cases were present year-round, suggesting that other fish could be involved in transmission to humans. Because of increased salmon trade, increased tourism in Japan, and lack of awareness of the risks associated with eating raw fish, cases of D. nihonkaiense diphyllobothriasis are expected to rise. Therefore, information regarding these concerning parasitic infections and warnings of the potential risks associated with these infections must be disseminated to consumers, food producers, restaurant owners, physicians, and travelers.
