OBJECTIVES Scrub typhus is the most common febrile disease in Korea during the autumn. Jeju Island is the largest island in South Korea and has a distinctive oceanic climate. This study aimed to identify epidemiologic characteristics of scrub typhus on Jeju Island.
METHODS
From January 2011 to December 2016, 446 patients were diagnosed with scrub typhus on Jeju Island. The patients’ personal data and the environmental factors that might be related to scrub typhus were investigated and retrospectively analyzed.
RESULTS
The median age of the patients was 58-years-old (range, 8 to 91) and 43% of them worked in the agricultural, forestry or livestock industry. Regardless of their job, 87% of the patients had a history of either working outdoors or of other activities before developing scrub typhus. The south and southeast regions of Jeju Island, especially Namwon-eup, showed the highest incidence of scrub typhus. Workers in mandarin orange orchards seemed to be the highest risk group for scrub typhus infection.
CONCLUSIONS
Scrub typhus on Jeju Island showed unique characteristics. To efficiently prevent scrub typhus, each year individual regional approaches should be developed based on the epidemiologic characteristics of the disease.
Summary
Korean summary
쯔쯔가무시증은 진드기에 의해 감염되는 대표적인 가을철 발열성 질환이다. 제주 지역에서 발생하는 쯔쯔가무시증의 역학적 특성을 분석한 결과 제주도의 남, 남동쪽이 다발생 지역으로 나타났다. 또한 이 지역의 감귤 농업이 쯔쯔가무시증이 발생할 수 있는 주요 위험요인인 것으로 추정된다.
