NNDSS - TABLE 1Q. Hepatitis B, perinatal infection to Hepatitis C, acute, Probable

NNDSS - TABLE 1Q. Hepatitis B, perinatal infection to Hepatitis C, acute, Probable - 2021. In this Table, provisional cases* of notifiable diseases are displayed for United States, U.S. territories, and Non-U.S. residents.

Notice: Due to data processing issues at CDC, data for the following jurisdictions may be incomplete for week 7: Alaska, Arizona, California, Connecticut, Delaware, Florida, Hawaii, Louisiana, Maryland, Michigan, Missouri, North Dakota, New Hampshire, New York City, Oregon, Pennsylvania, and Rhode Island.

Note:
This table contains provisional cases of national notifiable diseases from the National Notifiable Diseases Surveillance System (NNDSS). NNDSS data from the 50 states, New York City, the District of Columbia and the U.S. territories are collated and published weekly on the NNDSS Data and Statistics web page (https://wwwn.cdc.gov/nndss/data-and-statistics.html). Cases reported by state health departments to CDC for weekly publication are provisional because of the time needed to complete case follow-up. Therefore, numbers presented in later weeks may reflect changes made to these counts as additional information becomes available. The national surveillance case definitions used to define a case are available on the NNDSS web site at https://wwwn.cdc.gov/nndss/. Information about the weekly provisional data and guides to interpreting data are available at: https://wwwn.cdc.gov/nndss/infectious-tables.html.

Footnotes:
U: Unavailable — The reporting jurisdiction was unable to send the data to CDC or CDC was unable to process the data.
-: No reported cases — The reporting jurisdiction did not submit any cases to CDC.
N: Not reportable — The disease or condition was not reportable by law, statute, or regulation in the reporting jurisdiction.
NN: Not nationally notifiable — This condition was not designated as being nationally notifiable.
NP: Nationally notifiable but not published.
NC: Not calculated — There is insufficient data available to support the calculation of this statistic.
Cum: Cumulative year-to-date counts.
Max: Maximum — Maximum case count during the previous 52 weeks.
* Case counts for reporting years 2020 and 2021 are provisional and subject to change. Cases are assigned to the reporting jurisdiction submitting the case to NNDSS, if the case's country of usual residence is the U.S., a U.S. territory, unknown, or null (i.e. country not reported); otherwise, the case is assigned to the 'Non-U.S. Residents' category. Country of usual residence is currently not reported by all jurisdictions or for all conditions. For further information on interpretation of these data, see https://wwwn.cdc.gov/nndss/document/Users_guide_WONDER_tables_cleared_final.pdf.
†Previous 52 week maximum and cumulative YTD are determined from periods of time when the condition was reportable in the jurisdiction (i.e., may be less than 52 weeks of data or incomplete YTD data).
§ For acute Hepatitis C, only confirmed cases were verified.

国家法定传染病监测系统（National Notifiable Diseases Surveillance System, NNDSS）表1Q：2021年疑似急性丙型肝炎、围生期乙型肝炎病例。本表格展示了美国、美国领地及非美国居民的法定传染病暂报病例*数据。

注意：受美国疾病控制与预防中心（Centers for Disease Control and Prevention, CDC）数据处理流程影响，以下辖区第7周的相关数据可能存在不完整情况：阿拉斯加州、亚利桑那州、加利福尼亚州、康涅狄格州、特拉华州、佛罗里达州、夏威夷州、路易斯安那州、马里兰州、密歇根州、密苏里州、北达科他州、新罕布什尔州、纽约市、俄勒冈州、宾夕法尼亚州及罗德岛州。

说明：
本表格收录了来自国家法定传染病监测系统（National Notifiable Diseases Surveillance System, NNDSS）的全国法定传染病暂报病例数据。该系统每周汇总全美50个州、纽约市、哥伦比亚特区及美国领地的NNDSS数据，并发布于NNDSS数据与统计官方网页（https://wwwn.cdc.gov/nndss/data-and-statistics.html）。各州卫生部门向CDC上报用于每周发布的病例数据为暂报数据，原因是完成病例随访工作需要一定周期。因此，后续周次公布的统计数值可能会因获取到更多补充信息而进行调整。用于界定病例的全国监测病例定义可访问NNDSS官方网站（https://wwwn.cdc.gov/nndss/）查询。关于每周暂报数据及数据解读指南的相关信息，可访问：https://wwwn.cdc.gov/nndss/infectious-tables.html。

脚注：
U：数据不可用——上报辖区无法向CDC提交数据，或CDC无法完成该数据的处理流程。
-：无上报病例——上报辖区未向CDC提交任何相关病例。
N：无需上报——根据上报辖区的法律、法规或规章，该疾病或病症不属于法定上报范畴。
NN：非全国法定上报疾病——该病症未被纳入全国法定上报疾病名录。
NP：属于全国法定上报疾病但未予发布。
NC：未计算——无足够支撑数据以完成该统计量的计算。
Cum：年度至今（Year-to-Date, YTD）累计计数。
Max：最大值——过去52周内的最高病例统计值。
* 2020年与2021年的病例计数为暂报数据，仍存在调整可能。病例将被分配至提交该病例至NNDSS的上报辖区，前提为病例的常住国为美国、美国领地、未知或未上报（即无国家信息）；否则，该病例将被归类至非美国居民类别。目前并非所有辖区或所有病症都会上报常住国信息。如需进一步了解此类数据的解读方法，请参阅：https://wwwn.cdc.gov/nndss/document/Users_guide_WONDER_tables_cleared_final.pdf。
† 过去52周最大值及年度至今累计数据，是基于该病症在辖区内可上报的时间段计算得出（即可能不足52周的有效数据或不完整的年度至今统计数据）。
§ 仅对确诊的急性丙型肝炎病例进行了核实确认。
