Outline of Final Research Achievements

We investigated disease suppression services using SFTS, a zoonotic disease, as a model and found that biodiversity degradation, such as a significant increase in the density of large wild animals and exotic mammals, is a factor. In particular, we found that the increase and expansion of the distribution of Japanese deer and non-native raccoons are involved in the increase and expansion of the infection of SFTS-transmitting tick species. In addition, plant coverage was estimated to be involved in the increase of ticks, and humidity was estimated to have a significant effect on the tick survival. In ecosystem management as a countermeasure against these factors, we suggested that tick density management, including wildlife density management at the macroscale and vegetation management at the microscale, would be effective.

Academic Significance and Societal Importance of the Research Achievements

ワンヘルスアプローチに代表されるように、野生動物由来の人獣共通感染症についてはリスク低下やコストの観点から、野生動物、媒介生物および生態系の適切な管理によって、病原体が人の社会に侵入、定着、蔓延することの予防に重点的に取り組む必要がある。本研究は、マクロ、ミクロの両スケールにおいて何をなすべきかを科学的に分析し、提言した。
