AbstractAbstract AbstractSummary PDFSupplementary Material
The 2019 hepatitis A outbreak has become increasingly prevalent among adults in Korea and is the largest outbreak since that in 2009-2010. The incidence in the current outbreak is highest among adults aged 35-44 years, corresponding to the peak incidence among those aged 25-34 years 10 years ago. This may indicate a cohort effect in the corresponding age group. Causes of these repeated outbreaks of hepatitis A in Korea are low level of immunity among adults, Korean food culture that consumes raw seafood such as salted clam and inadequate public health system. Among countermeasures, along with general infectious disease control measures including control of the infectious agent, infection spread, and host, urgent actions are needed to review the vaccination policy and establish an adequate public health system.
Korean summary
2019년 한국 성인의 A형 간염 유행은 10년전 대규모 유행 이후 가장 큰 규모로발생하고 있다. 주 발생 연령이 10년전 유행보다 10세가 증가한 35-44세로 나타나 연령 코호트 효과라 볼 수 있다. 우리나라의 A형 간염 반복 유행의 원인은 성인의 낮은 집단면역수준, 어패류 생식문화, 공중보건의료체계 미비 등으로 보인다. 이에 대한 대책은 일반적인 감염관리대책인 감염원관리, 전파관리, 숙주관리와 함께 효율적인 백신접종정책, 공고한 공중보건관리체계 마련 등의 근본적 대책이 시급하다.
