NNDSS Weekly Data

NNDSS - In this Table, provisional cases* of notifiable diseases are displayed for United States, U.S. territories, and Non-U.S. residents.

Notes:

• These are weekly cases of selected infectious 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 available at https://www.cdc.gov/nndss/data-statistics/index.html. Cases reported by state health departments to CDC for weekly publication are subject to ongoing revision of information and delayed reporting. Therefore, numbers listed in later weeks may reflect changes made to these counts as additional information becomes available. Case counts in the tables are presented as published each week. See also Guide to Interpreting Provisional and Finalized NNDSS Data.

• Notices, errata, and other notes are available in the Notice To Data Users page.

• The list of national notifiable infectious diseases and conditions and their national surveillance case definitions are available at https://ndc.services.cdc.gov/. This list incorporates the Council of State and Territorial Epidemiologists (CSTE) position statements approved by CSTE for national surveillance.

Footnotes:

*Case counts for reporting years 2023 and 2024 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://www.cdc.gov/nndss/docs/Readers-Guide-WONDER-Tables-20210421-508.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).
• Please refer to the CDC WONDER publication for weekly updates to the footnote for influenza-associated pediatric mortality.
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.

NNDSS - 本表展示了美国、美属领土以及非美国居民的传染病报告病例的临时数据。注释：

• 本表所列之病例为每周所选定的传染病报告病例，数据来源于国家传染病监测系统（NNDSS）。NNDSS数据由各州、纽约市、哥伦比亚特区以及美属领土报告，并按周整理并发布为编号表格，可在https://www.cdc.gov/nndss/data-statistics/index.html查阅。向CDC报告以供每周发布的病例数据可能持续修订，并存在延迟报告的情况。因此，后续周次中列出的数字可能因新增信息而发生变化。表格中的病例计数按每周发布的数据呈现。另请参阅解读临时和最终NNDSS数据的指南。

• 注意事项、勘误及其他说明可在数据用户通知页面查阅。

• 国家报告传染病和条件及其国家监测病例定义的列表可在https://ndc.services.cdc.gov/查阅。该列表纳入了经国家州和地方流行病学家委员会（CSTE）批准的国家监测立场声明。

脚注：

*2023年和2024年的病例计数为临时数据，可能发生变化。如果病例的常住国家为美国、美属领土、未知或未报告（即未报告国家），则病例将被分配至提交病例至NNDSS的报告管辖区域；否则，病例将被分配至“非美国居民”类别。目前并非所有管辖区域或所有条件都报告常住国家。有关这些数据的解读，请参阅https://www.cdc.gov/nndss/docs/Readers-Guide-WONDER-Tables-20210421-508.pdf。

†前52周最大值和累计年度至今数据是根据条件在该管辖区域可报告的时间段确定的（即可能少于52周的数据或年度至今数据不完整）。

• 请参考CDC WONDER出版物，获取有关流感相关儿童死亡率的脚注每周更新。

U：不可用——报告管辖区域无法向CDC发送数据，或CDC无法处理数据。

-：无报告病例——报告管辖区域未向CDC提交任何病例。

N：不可报告——在报告管辖区域，疾病或条件根据法律、法规或条例不可报告。

NN：非全国性报告——此条件未被指定为全国性报告条件。

NP：全国性报告但未发布。

NC：未计算——缺乏足够的数据支持此统计数据的计算。

Cum：累计年度至今计数。
