From 2000 to 2010, there were 808 and 2,738 incident cases of acute and chronic hepatitis C, respectively, among active component members of the U.S. Armed Forces; crude overall incidence rates during the period were 5.16 (acute hepatitis C) and 17.48 (chronic hepatitis C) per 100,000 person-years. Incidence rates of acute hepatitis C diagnoses steadily declined (by approximately 80 percent overall) during the period; rates of chronic hepatitis C diagnoses also declined but proportionately less overall than for acute hepatitis C. Declining trends likely reflect avoidance of risky behaviors, comprehensive screening of blood products, and accession standards that include screening for illicit drugs and antibodies to HIV-1.
2000年至2010年期间，美国武装部队现役成员中分别有808例和2738例急性和慢性丙型肝炎新发病例；该期间的总体粗发病率分别为每10万人年5.16例（急性丙型肝炎）和17.48例（慢性丙型肝炎）。在此期间，急性丙型肝炎诊断发病率稳步下降（总体下降约80%）；慢性丙型肝炎诊断发病率也有所下降，但总体下降幅度小于急性丙型肝炎。下降趋势可能反映了危险行为的避免、血液制品的全面筛查以及包括非法药物筛查和HIV-1抗体筛查在内的入伍标准。
