NNDSS - TABLE 1V. Malaria to Measles, Imported

NNDSS - TABLE 1V. Malaria to Measles, Imported - 2019. In this Table, provisional cases* of notifiable diseases are displayed for United States, U.S. territories, and Non-U.S. residents.

Notice: The total numbers of measles cases in Table 1v for weeks 1-51 in the 2019 data are correct but counts for imported and indigenous categories are incorrect. Measles data for week 52 (in Table 1v) were updated on 02-28-2020 to correct the classification of imported and indigenous. Please see week 52, 2019 data for the correct breakout of imported and indigenous measles cases.

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 — CDC does not have data because of changes in how conditions are categorized.
Cum: Cumulative year-to-date counts.
Max: Maximum — Maximum case count during the previous 52 weeks.
* Case counts for reporting years 2018 and 2019 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 US, a US territory, unknown, or null (i.e. country not reported); otherwise, the case is assigned to the 'Non-US Residents' category. 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).

§ Measles is considered imported if the disease was acquired outside of the United States and is considered indigenous if the disease was acquired anywhere within the United States or it is not known where the disease was acquired.

NNDSS - 表格1V. 疟疾至麻疹，输入性 - 2019年。本表展示了美国、美国领土以及非美国居民的报告传染病暂定病例数。

注意：表格1v中2019年1-51周麻疹病例总数正确，但输入性和本土性病例的计数有误。2019年第52周（表格1v）的数据于2020年2月28日更新，以纠正输入性和本土性病例的分类。请参阅2019年第52周的数据以获取正确的输入性和本土性麻疹病例分布。

备注：
本表包含国家报告传染病系统（NNDSS）的国家报告传染病暂定病例数。NNDSS数据来自50个州、纽约市、哥伦比亚特区以及美国领土，并每周在NNDSS数据与统计网页（https://wwwn.cdc.gov/nndss/data-and-statistics.html）上发布。由于病例追踪所需时间，向CDC报告并由CDC进行每周发布的病例暂定为暂定病例。因此，后期周次的数字可能反映随着信息的进一步提供而对这些计数所做的更改。用于定义病例的国家监测病例定义可在NNDSS网站（https://wwwn.cdc.gov/nndss/）上找到。有关每周暂定数据和信息解读的指南可在：https://wwwn.cdc.gov/nndss/infectious-tables.html上获取。

脚注：
U：不可用 —— 报告辖区无法向CDC发送数据，或CDC无法处理数据。
-：无报告病例 —— 报告辖区未向CDC提交任何病例。
N：不可报告 —— 疾病或条件在报告辖区根据法律、法规或条例不可报告。
NN：非全国性报告 —— 此状况未指定为全国性报告。
NP：全国性报告但未发布 —— 由于条件分类方式的变化，CDC没有数据。
Cum：累积至当日年度计数。
Max：最大值 —— 过去52周内的最大病例数。
* 2018年和2019年报告年的病例数为暂定数，可能发生变化。如果病例的常住国家为美国、美国领土、未知或空（即未报告国家），则病例被分配给提交病例给NNDSS的报告辖区；否则，病例被分配到“非美国居民”类别。有关这些数据的解读进一步信息，请参阅https://wwwn.cdc.gov/nndss/document/Users_guide_WONDER_tables_cleared_final.pdf。
† 过去52周的最大值和累积至当日年度数据是从条件在辖区可报告的时期确定的（即可能少于52周的数据或不完整的累积至当日年度数据）。
§ 麻疹如果是在美国境外获得的，则被认为是输入性的；如果在任何美国境内获得或无法确定获得地点，则被认为是本土性的。
