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 - 2019. In this Table, provisional cases* of notifiable diseases are displayed for United States, U.S. territories, and Non-U.S. residents.

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).
§ 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Junin病毒至Viral hemorrhagic fevers，Lujo病毒 - 2019。本表展示了美国、美国领土以及非美国居民的传染病报告病例的临时数据*。

注：
本表收录了国家传染病报告系统的临时病例数据，该系统数据由美国各州、纽约市、哥伦比亚特区以及美国领土汇总并每周发布于NNDSS数据与统计网页（https://wwwn.cdc.gov/nndss/data-and-statistics.html）。各州卫生部门向CDC报告的病例因病例随访所需时间而呈现为临时数据。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的信息可在：https://wwwn.cdc.gov/nndss/infectious-tables.html。

脚注：
U：不可用 — 报告机构无法向CDC发送数据或CDC无法处理数据。
-：无报告病例 — 报告机构未向CDC提交任何病例。
N：不可报告 — 在报告机构，该疾病或状况根据法律、法规或条例不具报告义务。
NN：非国家报告 — 此状况未被指定为国家报告。
NP：国家报告但未发布 — 由于条件分类方式的变化，CDC未获得数据。
Cum：累计至今年度计数。
Max：最大值 — 过去52周内的最大病例数。
*2018年和2019年的病例计数为临时数据，可能发生变化。如果病例的居住国为美国、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的报告机构；否则，病例将被分配至'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。
†前52周的最大值和累计至今数据是根据该机构报告义务期间的数据确定的（即可能少于52周的数据或累计至今数据不完整）。
§2015年之前，美国疾病控制与预防中心（CDC）的国家传染病报告系统（NNDSS）未接收有关特定病毒性出血热病例的电子数据；相反，数据以“病毒性出血热”的汇总形式收集。自2015年起，NNDSS更新以接收所列病毒性出血热的数据。
