NNDSS - TABLE 1NN. Viral hemorrhagic fevers, Junin virus to Viral hemorrhagic fevers, Lujo virus

NNDSS - TABLE 1NN. Viral hemorrhagic fevers, Junin virus to Viral hemorrhagic fevers, Lujo virus – 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).
§ Prior to 2015, CDC's National Notifiable Diseases Surveillance System (NNDSS) did not receive electronic data about incident cases of specific viral hemorrhagic fevers; instead data were collected in aggregate as "viral hemorrhagic fevers". NNDSS was updated beginning in 2015 to receive data for each of the viral hemorrhagic fevers listed.

NNDSS - 表格 1NN. 病毒性出血热，自胡宁病毒至卢若病毒，2021年数据。本表展示了美国、美国领土及非美国居民报告的可通报疾病的临时病例数*。

注意：由于美国疾病控制与预防中心（CDC）数据处理问题，以下地区的7周数据可能不完整：阿拉斯加、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、宾夕法尼亚州和罗德岛州。

备注：
本表收录了来自国家可通报疾病监测系统（NNDSS）的国家可通报疾病的临时病例数。NNDSS从50个州、纽约市、哥伦比亚特区及美国领土收集并每周发布在NNDSS数据与统计网页上（https://wwwn.cdc.gov/nndss/data-and-statistics.html）。各州卫生部门向CDC报告的病例，由于需要完成病例追踪的时间，因此这些病例为临时病例。因此，后续周次中呈现的数字可能会随着新信息的出现而发生变化。用于定义病例的国家监测病例定义可在NNDSS网站上查阅（https://wwwn.cdc.gov/nndss/）。有关每周临时数据及数据解读指南，请参阅：https://wwwn.cdc.gov/nndss/infectious-tables.html。

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 —— 在报告辖区，该疾病或状况根据法律、法规或条例不可报告。
NN：非全国性可报告 —— 该状况未被指定为全国性可报告。
NP：全国性可报告但未发布。
NC：未计算 —— 可用数据不足以支持此统计量的计算。
Cum：累计年度至今数。
Max：最大值 —— 过去52周内的最大病例数。
*2020年和2021年的病例数属于临时数据，可能发生变化。如果病例的常住国家为美国、美国领土、未知或未报告（即国家未报告），则病例将被分配给提交病例至NNDSS的报告辖区；否则，病例将被分配至“非美国居民”类别。目前并非所有辖区或所有状况都报告常住国家。有关这些数据的解读，请参阅https://wwwn.cdc.gov/nndss/document/Users_guide_WONDER_tables_cleared_final.pdf。
†过去52周的最大值和累计年度至今数是根据报告辖区报告状况为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）。
§在2015年之前，美国疾病控制与预防中心（CDC）的国家可通报疾病监测系统（NNDSS）未接收有关特定病毒性出血热病例事件的电子数据；相反，数据以“病毒性出血热”的汇总形式收集。自2015年开始，NNDSS更新以接收列出的每种病毒性出血热的数据。
