NNDSS - Table II. Hepatitis (viral, acute) C

NNDSS - Table II. Hepatitis (viral, acute) C - 2017. In this Table, provisional cases of selected notifiable diseases (≥1,000 cases reported during the preceding year), and selected low frequency diseases are displayed. The Table includes total number of cases reported in the United States, by region and by states, in accordance with the current method of displaying MMWR data. Data on United States exclude counts from US territories.

Note:
These are provisional cases of selected national notifiable diseases, from the National Notifiable Diseases Surveillance System (NNDSS). NNDSS data reported by the 50 states, New York City, the District of Columbia, and the U.S. territories are collated and published weekly as numbered tables printed in the back of the Morbidity and Mortality Weekly Report (MMWR). Cases reported by state health departments to CDC for weekly publication are provisional because of ongoing revision of information and delayed reporting.

Case counts in this table are presented as they were published in the MMWR issues. Therefore, numbers listed in later MMWR weeks may reflect changes made to these counts as additional information becomes available.

Footnotes:
C.N.M.I.: Commonwealth of Northern Mariana Islands.

U: Unavailable. —: No reported cases. N: Not reportable. NN: Not Nationally Notifiable. NP: Nationally notifiable but not published. Cum: Cumulative year-to-date counts. Med: Median. Max: Maximum.

*Three low incidence conditions, rubella, rubella congenital, and tetanus, are in Table II to facilitate case count verification with reporting jurisdictions.

† Case counts for reporting year 2017 are provisional and subject to change. For further information on interpretation of these data, see http://wwwn.cdc.gov/nndss/document/ ProvisionalNationaNotifiableDiseasesSurveillanceData20100927.pdf. Data for tuberculosis are displayed in Table IV, which appears quarterly.

§ Based on the CSTE Position Statement 15-ID-03: Revision of the Case Definition of Hepatitis C for National Notification, acute hepatitis C is now reported by case classification status.

国家法定传染病监测系统（National Notifiable Diseases Surveillance System, NNDSS）表格二：2017年急性病毒性丙型肝炎
本表格涵盖两类病例：一类为上年报告病例数≥1000例的选定法定传染病的暂定病例，另一类为选定的低发传染病病例。本表格按照当前《发病率与死亡率周报》（Morbidity and Mortality Weekly Report, MMWR）的数据展示规范，列示了美国按区域、州划分的报告病例总数，美国统计数据不含美国领土地区的相关计数。

### 备注
本数据来源于国家法定传染病监测系统（National Notifiable Diseases Surveillance System, NNDSS），所列为选定的全国法定传染病的暂定病例。全美50个州、纽约市、哥伦比亚特区以及美国领土地区上报至NNDSS的数据，经汇总整理后以编号表格形式每周发布于《发病率与死亡率周报》（Morbidity and Mortality Weekly Report, MMWR）的末页。各州卫生部门上报至美国疾病控制与预防中心（Centers for Disease Control and Prevention, CDC）以供每周发布的病例数据为暂定数据，原因在于相关信息仍在持续修订且存在报告延迟情况。

本表格中的病例计数完全沿用MMWR各期的原始发布格式，因此后续MMWR各期刊载的对应数据可能会随着新信息的补充而发生调整。

### 脚注
C.N.M.I.：北马里亚纳群岛联邦（Commonwealth of Northern Mariana Islands）
U：数据不可用；—：无报告病例；N：无需报告；NN：未纳入全国法定报告范畴；NP：属于全国法定报告疾病但未予发布；Cum：本年度累计计数；Med：中位数；Max：最大值。
*本表格二纳入风疹、先天性风疹以及破伤风三种低发传染病，以便与报告辖区开展病例计数核对工作。
† 本次报告年度为2017年的病例计数为暂定数据，仍存在调整空间。如需了解上述数据的解读细则，请参阅：http://wwwn.cdc.gov/nndss/document/ProvisionalNationalNotifiableDiseasesSurveillanceData20100927.pdf（注：原链接存在拼写及空格错误，已修正）。肺结核相关数据刊载于按季度发布的表格四中。
§ 根据美国州与领土流行病学专家委员会（Council of State and Territorial Epidemiologists, CSTE）第15-ID-03号立场声明《全国法定报告丙型肝炎病例定义修订》，当前急性丙型肝炎需按病例分类状态进行报告。
