전투 경찰에서 A형 간염 발생률과 항체 양성률 = Incidence and Seroprevalence of Hepatitis A Virus among Korean Auxiliary Police Officers

다국어 초록 (Multilingual Abstract)

Background: In Korea, cases with hepatitis A have been reported to Korea Centers for Disease Control and Prevention through the sentinel surveillance system. However, it was difficult to study the exact nation-wide incidence of hepatitis A infection. We studied the incidence of clinically apparent hepatitis A infection and the seroprevalence of anti-HAV IgG among auxiliary police officers.
Materials and methods: We analyzed clinically apparent and hospitalized hepatitis A patients from 2002 to 2006 in National Police Hospital via medical records. We also measured anti-HAV IgG antibody from 507 auxiliary police officers.
Results: The estimated annual incidence of clinically apparent hepatitis A infection among auxiliary police officers was 10.6-14.8 cases per 100,000 population from 2002 to 2006. The overall anti-HAV IgG seropositive rate among auxiliary police officers was 0.6% (3/507).
Conclusion: Among auxiliary police officers, the estimated annual incidence of clinically apparent hepatitis A infection was above 10 cases per 100,000 population and the positive rate of anti-HAV IgG was very low. The results were comparable to those in the low endemicity countries. The routine HAV vaccination among auxiliary police officers might be suggested.

국문 초록 (Abstract)

목 적 : 우리나라에서 A형 간염은 표본 감시를 통해서 질병관리본부로 보고되고 있으나 전체 모집단을 규정할 수 없어 A형 간염 발생률을 조사하기는 어렵다. 이에 저자들은 단일 집단인 전투 경찰을 대상으로 연간 현증 A형 간염의 발생률 및 항체 양성률을 조사하고자 하였다.
재료 및 방법 : 의무기록 검색을 통하여 2002년부터 2006년까지 국립경찰병원에 입원하여 현증 A형 간염으로 진단된 전투 경찰을 조사하였다. 그리고 전투 경찰 507명을 대상으로 A형 간염 바이러스 항체를 검사하였다.
결 과 : 2002년부터 2006년까지 전투 경찰에서 연간 현증 감염의 발생률은 10만 명당 10.6-14.8명이었다. 건강한 전투 경찰의 A형 간염 바이러스 항체 양성률은 0.6% (3/ 507)이었다.
결 론 : 전투 경찰에서 연간 현증 A형 간염 발생률은 10만 명당 10명 이상이며, 전투 경찰의 A형 간염 항체 양성률은 1999년 30.2%에서 현재 0.6%로 현저히 낮아졌다. 전투 경찰에서 A형 간염 백신을 기본 접종할 것을 고려해야 한다.
