Abstract

Anthropogenic disturbances degrade ecosystems, elevating the risk of emerging infectious diseases from wildlife. However, the key environmental factors for preventing tick-borne disease infection in relation to host species, landscape components, and climate conditions remain unknown. This study focuses on identifying crucial environmental factors contributing to the outbreak of severe fever with thrombocytopenia syndrome (SFTS), a tick-borne disease, in Miyazaki Prefecture, southern Japan. We collected data on SFTS case numbers, annual temperature and precipitation, species richness of large- and middle-sized mammals, forest perimeter length (indicating the amount of forest boundaries), percentage of agricultural land, human population, and sightseeing place numbers for each 25 km² grid cell encompassing Miyazaki Prefecture. Through the construction of a model incorporating these factors, we found that longer forest perimeter and higher temperature led to a higher number of SFTS cases. Precipitation, mammal species richness, percentage of agricultural land, human population, and sightseeing point numbers had no effect on SFTS case numbers. In conclusion, climate condition and forest fragmentation, which increase the opportunity for human infection, played a pivotal role in SFTS outbreak.

森林破碎化和气候变暖增加了蜱传疾病的感染。

人为干扰使生态系统退化，增加了野生动物新发传染病的风险。然而，与宿主物种、景观成分和气候条件有关的预防蜱传疾病感染的关键环境因素仍然未知。本研究的重点是确定在日本南部宫崎县导致严重发热伴血小板减少综合征（SFTS）暴发的关键环境因素，SFTS是一种蜱传疾病。我们收集了宫崎县周围每25 km2网格单元的SFTS病例数、年气温和降水量、大中型哺乳动物物种丰富度、森林周长（表明森林边界的数量）、农业用地百分比、人口和观光景点数量等数据。通过建立综合这些因素的模型，我们发现森林周长和温度越高，导致SFTS病例数越多。降水量、哺乳动物物种丰富度、农业用地比例、人口和观光景点数量对SFTS病例数没有影响。综上所述，气候条件和森林破碎化增加了人类感染的机会，在SFTS暴发中发挥了关键作用。

期刊介绍： EcoHealth aims to advance research, practice, and knowledge integration at the interface of ecology and health by publishing high quality research and review articles that address and profile new ideas, developments, and programs. The journal’s scope encompasses research that integrates concepts and theory from many fields of scholarship (including ecological, social and health sciences, and the humanities) and draws upon multiple types of knowledge, including those of relevance to practice and policy. Papers address integrated ecology and health challenges arising in public health, human and veterinary medicine, conservation and ecosystem management, rural and urban development and planning, and other fields that address the social-ecological context of health. The journal is a central platform for fulfilling the mission of the EcoHealth Alliance to strive for sustainable health of people, domestic animals, wildlife, and ecosystems by promoting discovery, understanding, and transdisciplinarity. The journal invites substantial contributions in the following areas: One Health and Conservation Medicine o Integrated research on health of humans, wildlife, livestock and ecosystems o Research and policy in ecology, public health, and agricultural sustainability o Emerging infectious diseases affecting people, wildlife, domestic animals, and plants o Research and practice linking human and animal health and/or social-ecological systems o Anthropogenic environmental change and drivers of disease emergence in humans, wildlife, livestock and ecosystems o Health of humans and animals in relation to terrestrial, freshwater, and marine ecosystems Ecosystem Approaches to Health o Systems thinking and social-ecological systems in relation to health o Transdiiplinary approaches to health, ecosystems and society.
