Abstract

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.

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.

Abstract

OBJECTIVES
Recently kudoa septempuctata in olive flounders is suggested as a cause of food poisoning, however whether kudoa septempuctata can affect human gastrointestinal systems is controversial and its pathogenecity remains unclear. In view of the field epidemiology, food poisonings caused by kudoa septempuctata should be distinguished from those caused by staphylococcus aureus and bacillus cereus.

METHODS

The statistics of food poisoning investigations published by Korea Centers for Disease Control and Prevention in 2013-2015 were reviewed. The characteristics of kudoa septempuctata food poisoning reported by Korea Centers for Disease Control and Prevention were reviewed. Information regarding clinical symptoms or epidemiology was extracted.

RESULTS

Total eleven kudoa septempuctata food poisoning cases were analyzed. Food poisonings caused by kudoa septempuctata, staphylococcus aureus and bacillus cereus have clinical and epidemiological similarities. Forty five percent of food poisoning outbreaks occurred in Korea was concluded as unknown. The food poisoning caused by staphylococcus aureus and bacillus cereus accounted for 4.5% (50/1,092) of all food poisoning outbreaks in Korea between 2013 and 2015.

CONCLUSIONS

This study suggests the possibilities of misdiagnosis in the investigations of food poisoning by staphylococcus aureus and bacillus cereus with kudoa septempuctata.

최근 광어 섭취 후 발생한 식중독의 한 원인으로 쿠도아충이 지목되고 있다. 하지만 쿠도아충에 의한 식중독은 인체 감염에 대한 근거가 부족하고, 황색포도알균이나 바실루스 세레우스 식중독과 감별이 어려워 진단에 있어 주의를 요한다.
