Influenza Laboratory-Confirmed Cases by County: Beginning 2009-10 Season

This dataset includes weekly counts of laboratory-confirmed influenza (flu) cases, by county and influenza type, going back to the 2009-10 season. The primary goal of this dataset is to provide users timely information about local influenza activity throughout the current influenza season. Although each influenza season is unique, historical data is also provided for trend comparison. In view of persisting elevated influenza activity throughout NYS, NYSDOH is extending the surveillance 2021-2022 season beyond May until influenza activity has decreased. <b>In view of persisting elevated influenza activity throughout NYS, NYSDOH is extending the surveillance season beyond May until influenza activity has decreased.</b>

Cases are included that meet the New York State Department of Health’s (NYSDOH) standardized case definition, i.e., a positive result on any of the following influenza laboratory tests:
• Rapid Influenza Diagnostic Tests (RIDT)
• Immunofluorescence assays (DFA and IFA)
• Rapid Molecular Assays
• Reverse Transcriptase Polymerase Chain Reaction (RT-PCR)
• Other Nucleic Acid Amplification tests
• Viral Culture
Please see the overview document for more details about NYSDOH’s influenza case definition. Cases reported during the CDC-defined influenza surveillance season (week 40-week 20 of the next calendar year; October through mid-May) are included.

本数据集收录了自2009-10流感季节以来的每周实验室确诊流感病例数，按县和流感类型分类。该数据集的主要目标是为用户提供有关当前流感季节本地流感活动的及时信息。尽管每个流感季节都具有独特性，但同时也提供了历史数据以供趋势比较。鉴于纽约州流感活动持续升高，纽约州卫生部门（NYSDOH）将2021-2022流感季节的监测期延长至五月之后，直至流感活动下降。以下为强调性句子：<b>鉴于纽约州流感活动持续升高，纽约州卫生部门（NYSDOH）将流感季节的监测期延长至五月之后，直至流感活动下降。</b>所收录的病例均符合纽约州卫生部门（NYSDOH）制定的标准化病例定义，即以下任何一项流感实验室检测结果为阳性：• 快速流感诊断测试（RIDT）；• 免疫荧光测定（DFA和IFA）；• 快速分子测定；• 反转录聚合酶链反应（RT-PCR）；• 其他核酸扩增测试；• 病毒培养。更多关于纽约州卫生部门（NYSDOH）流感病例定义的详细信息，请参阅概述文档。所报道的病例均包含在由美国疾病控制与预防中心（CDC）定义的流感监测季节内（当年第40周至次年日历年的第20周；十月至次年五月中期）。更多信息请参阅：http://www.health.ny.gov/diseases/communicable/influenza/surveillance/。
