A survey of rodents and chiggers associated with Orientia tsutsugamushi was conducted in a rural region of the Republic of Korea (Korea) between 2014 and 2018. Overall Apodemus agrarius 15.2% had the highest seropisitive for O. tsutsugamushi, followed by Myodes regulus 11.4%. Monthly risk factors using logistic regression analysis were not associated with O. tsutsugamushi infections in rodents. The overall prevalence rate of O. tsutsugamushi among chiggers was 0.3%. The chigger (Leptotrombidium scutellare) and monthly (October) risk factors were associated with O. tsutsugamushi human infections (P<0.05). Orientia tsutsugamushi infections are endemic in rodents in Korea and people, for example, soldiers who are active outdoors, must employ preventive measures, especially during October (P<0.05). When there are many reports of O. tsutsugamushi infections in Korea. The Boryong strain 85.7% (2/14) was the most common strain detected in chiggers, followed by the Shimokoshi 7.1% (1/14) and Karp 7.1% strains.
2014年至2018年期间，在大韩民国（韩国）的一个农村地区对与恙虫病东方体相关的啮齿动物和恙螨进行了调查。总体而言，黑线姬鼠对恙虫病东方体的血清阳性率最高，为15.2%，其次是棕背䶄，为11.4%。使用逻辑回归分析的月度风险因素与啮齿动物感染恙虫病东方体无关。恙螨中恙虫病东方体的总体患病率为0.3%。恙螨（小板恙螨）和月度（10月）风险因素与恙虫病东方体的人类感染有关（P<0.05）。恙虫病东方体感染在韩国的啮齿动物和人群中呈地方性流行，例如，在户外活跃的士兵必须采取预防措施，尤其是在10月（P<0.05）。韩国有许多恙虫病东方体感染的报告。在恙螨中检测到的最常见菌株是保宁菌株，占85.7%（2/14），其次是下越菌株，占7.1%（1/14），卡尔普菌株占7.1%。
