From 2000 to 2010, there were 214 incident diagnoses of acute hepatitis A among active component members of the U.S. Armed Forces; the crude overall incidence rate during the period was 1.37 per 100,000 person-years. Rates of incident diagnoses of acute hepatitis A were relatively low throughout the period and much lower than during the pre-vaccine era (1990-1996). There were disproportionate numbers of diagnoses of acute hepatitis A among service members born in countries endemic for the infection. The low rates of acute hepatitis A among U.S. military members overall reflect the widespread use of hepatitis A virus vaccine.
2000年至2010年期间，美国武装部队现役人员中有214例急性甲型肝炎确诊病例；该期间的总体粗发病率为每10万人年1.37例。在此期间，急性甲型肝炎的确诊率相对较低，远低于疫苗接种前时代（1990 - 1996年）。在出生于该感染流行国家的军人中，急性甲型肝炎的诊断病例数不成比例。美国军人中急性甲型肝炎的低发病率总体上反映了甲型肝炎病毒疫苗的广泛使用。
