Methods: We investigated raw data of TD outbreaks from the National Notifiable Disease Surveillance System of the Korea Diseases Control and Prevention Agency in Korea, and the National Institute of Infectious Diseases in Japan, 2016 to 2020.
Results: There were 36,785 cases of TD with a cumulative infectious rate (CIR) of 14.3 per 100,000 populations in Korea from 2016 to 2020. During the same period in Japan, there were 2,350 cases with a CIR of 0.4. When compared, Korea was much higher than that in Japan (P<0.01). In Korea, more females (60.2% of total cases) were infected than males (39.8%), while there was a significant difference between males (58.8%) and females (41.2%) in Japan, respectively (P<0.01).
Conclusion: These differences in TD risk factors reflect differences of vectors/hosts, climate, and geographical and cultural characteristics between the two countries. The surveillance of TD, primarily a zoonotic disease, should be continued in order to obtain a better understanding of its current status. Moreover, guidelines for the prevention of TD, and its control measures should be more established.
