Hepatitis C virus (HCV) infection is a major source of morbidity and mortality in the United States. HCV is transmitted primarily through parenteral exposures to infectious blood or body fluids that contain blood, most commonly through injection drug use. No vaccine against hepatitis C exists and no effective pre- or postexposure prophylaxis is available. More than half of persons who become infected with HCV will develop chronic infection. Direct-acting antiviral treatment can result in a virologic cure in most persons with 8-12 weeks of all-oral medication regimens. This report augments (i.e., updates and summarizes) previously published recommendations from CDC regarding testing for HCV infection in the United States (Smith BD, Morgan RL, Beckett GA, et al. Recommendations for the identification of chronic hepatitis C virus infection among persons born during 1945-1965. MMWR Recomm Rec 2012;61[No. RR-4]). CDC is augmenting previous guidance with two new recommendations: 1) hepatitis C screening at least once in a lifetime for all adults aged ≥18 years, except in settings where the prevalence of HCV infection is <0.1% and 2) hepatitis C screening for all pregnant women during each pregnancy, except in settings where the prevalence of HCV infection is <0.1%. The recommendation for HCV testing that remains unchanged is regardless of age or setting prevalence, all persons with risk factors should be tested for hepatitis C, with periodic testing while risk factors persist. Any person who requests hepatitis C testing should receive it, regardless of disclosure of risk, because many persons might be reluctant to disclose stigmatizing risks.
丙型肝炎病毒(HCV)感染是美国发病率和死亡率的主要原因。HCV 主要通过接触传染性血液或体液传播,这些体液中含有血液,最常见的途径是注射吸毒。目前尚无针对丙型肝炎的疫苗,也没有有效的预防或暴露后预防措施。超过一半感染 HCV 的人会发展为慢性感染。直接作用抗病毒治疗可使大多数人在 8-12 周的全口服药物治疗方案后实现病毒学治愈。本报告补充了(即更新和总结)CDC 之前发布的关于在美国检测 HCV 感染的建议(Smith BD、Morgan RL、Beckett GA 等人。关于在 1945-1965 年出生的人群中识别慢性丙型肝炎病毒感染的建议。MMWR Recomm Rec 2012;61[No. RR-4])。CDC 用两条新建议对之前的指导意见进行了补充:1)除 HCV 感染率<0.1%的环境外,所有 18 岁及以上成年人一生中至少应进行一次 HCV 筛查;2)除 HCV 感染率<0.1%的环境外,所有孕妇在每次妊娠期间都应进行 HCV 筛查。不变的 HCV 检测建议是,无论年龄或环境流行率如何,所有具有风险因素的人都应进行 HCV 检测,并在风险因素持续存在时定期检测。任何要求进行 HCV 检测的人都应接受检测,无论是否披露风险,因为许多人可能不愿意披露有污名的风险。
