NNDSS - Table I. infrequently reported notifiable diseases

NNDSS - Table I. infrequently reported notifiable diseases - 2018. In this Table, provisional cases of selected infrequently reported notifiable diseases (<1,000 cases reported during the preceding year) are displayed. This tables excludes U.S. territories.

Notice: The case counts for Haemophilus influenzae, invasive disease Nontypeable" and "Non-b serotype" were switched for 2018 weeks 1-52.

Note:
These are provisional cases of selected national notifiable diseases from the National Notifiable Diseases Surveillance System (NNDSS). NNDSS data from the 50 states, New York City, the District of Columbia are collated and published weekly on the NNDSS Data and Statistic 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.

Footnote:
—: No reported cases. N: Not reportable. NA: Not available. NN: Not Nationally Notifiable. NP: Nationally notifiable but not published. Cum: Cumulative year-to-date counts.

* Case counts for reporting years 2017 and 2018 are provisional and subject to change. Data for years 2013 through 2016 are finalized. For further information on interpretation of these data, see http://wwwn.cdc.gov/nndss/document/ProvisionalNationaNotifiableDiseasesSurveillanceData20100927.pdf.

† This table does not include cases from the U.S. territories.

§ Calculated by summing the incidence counts for the current week, the 2 weeks preceding the current week, and the 2 weeks following the current week, for a total of 5 preceding years. Additional information is available at https://wwwn.cdc.gov/nndss/document/5yearweeklyaverage.pdf.

¶ Not reportable in all jurisdictions. Data from states where the condition is not reportable are excluded from this table, except for the arboviral diseases and influenza-associated pediatric mortality. Reporting exceptions are available at http://wwwn.cdc.gov/nndss/downloads.html.

§§ Novel influenza A virus infections are human infections with influenza A viruses that are different from currently circulating human seasonal influenza viruses. With the exception of one avian lineage influenza A (H7N2) virus, all novel influenza A virus infections reported to CDC since 2013 have been variant influenza viruses.

¶¶ Prior to 2018, cases of paratyphoid fever were included with salmonellosis cases (see Table II).

*** 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I. 罕见上报法定传染病——2018年。

本表格展示了部分罕见上报的法定传染病的暂报病例数（上一年度上报病例不足1000例）。本表格不包含美国领土范围内的数据。

注意：2018年第1周至第52周，流感嗜血杆菌（Haemophilus influenzae）侵袭性疾病（不可分型）与“非B血清型”的病例计数曾被错误互换。

备注：
以下为美国国家法定传染病监测系统（National Notifiable Diseases Surveillance System, NNDSS）收录的部分国家级法定传染病暂报病例数据。NNDSS汇集了美国50个州、纽约市以及哥伦比亚特区的上报病例数据，每周均会在NNDSS数据与统计官方网页（https://wwwn.cdc.gov/nndss/data-and-statistics.html）发布。各州卫生部门上报至美国疾病控制与预防中心（Centers for Disease Control and Prevention, CDC）并用于每周发布的病例数为暂报数据，原因是完成病例随访与核查需要一定时间。因此，后续周次发布的统计数据可能会随着更多补充信息的获取而发生调整。用于界定病例的国家级监测病例定义可在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，可访问：https://wwwn.cdc.gov/nndss/infectious-tables.html。

脚注：
—：无上报病例。N：无法定上报要求。NA：无可用数据。NN：不属于国家级法定上报传染病。NP：属于国家级法定上报传染病但未公开发布。Cum：本年度截至当前的累计病例数。
* 2017年与2018年的病例计数均为暂报数据，后续可能进行调整。2013年至2016年的数据均已定稿。如需进一步了解此类数据的解读方法，可参阅文档：http://wwwn.cdc.gov/nndss/document/ProvisionalNationaNotifiableDiseasesSurveillanceData20100927.pdf。
† 本表格不包含美国领土范围内的病例数据。
§ 该统计值通过对当前周、当前周前2周及后2周的发病数求和计算得出，总计覆盖前5年周期。更多相关信息可访问：https://wwwn.cdc.gov/nndss/document/5yearweeklyaverage.pdf。
¶ 并非所有司法管辖区均要求上报此类传染病。除虫媒传染病与流感相关儿童死亡率外，本表格未纳入无需上报该传染病的州的相关数据。上报例外情况可查阅：http://wwwn.cdc.gov/nndss/downloads.html。

§§ 新型甲型流感病毒感染指人类感染与当前流行的人类季节性流感病毒不同的甲型流感病毒。自2013年以来向CDC上报的所有新型甲型流感病毒感染病例均为变异流感病毒，仅有一种禽源甲型流感（H7N2）病毒除外。
¶¶ 2018年之前，副伤寒病例被纳入沙门氏菌病病例统计范畴（详见表II）。
*** 2015年之前，美国疾控中心（CDC）的国家法定传染病监测系统（NNDSS）并未接收特定病毒性出血热的单例电子发病数据，而是以“病毒性出血热”为统称进行汇总收集。自2015年起，NNDSS完成系统升级，可分别接收本表格所列各类病毒性出血热的单项数据。
