概括

COVID-19大流行严重影响了类似流感的疾病 (ILI) 和流感阳性率 (IPR),导致下降,随后反弹. ILI和IPR之间的关系在各个流行病阶段各不相同,强调需要综合监测.

科学领域:

流行病学流行病学
病毒学病毒学
公共卫生公共卫生

背景情况:

分析2016年至2024年的昆州流感样疾病 (ILI) 和流感阳性率 (IPR) 数据.
评估COVID-19大流行对流感监测指标的影响.

研究的目的:

评估COVID-19流行病对流感流行病学的影响.
检查不同流行病阶段LI和IPR之间的动态关系.

主要方法:

利用来自哨兵医院和网络实验室的ILI每周监测数据.
用实时逆转录聚合酶链反应 (RT-PCR) 来识别流感病毒.
分析了77,912个报告的ILI病例和相应的流感阳性率.

主要成果:

在COVID-19大流行期间 (2020-2022) 观察到ILI%和IPR的显著下降,随后是流行后的反弹.
确定15岁以下的儿童是ILI病例中比例最高的,而5-14岁的年龄组显示出IPR最高.
在各个流行病阶段展示了ILI%和IPR之间的不同相关性:流行病前的阳性弱,流行病期间的中度阴性和流行病后的中度阳性.

结论:

随着COVID-19的流行,流感活动和ILI-IPR的关系发生了重大变化.
不一致的相关性强调需要综合病毒学监测和精确的ILI定义,以有效监测流感.
调查结果强调了调整公共卫生应对流行病引起的流行病学转变的重要性.

Steps in Outbreak Investigation

In the ever-evolving field of public health, statistical analysis serves as a cornerstone for understanding and managing disease outbreaks. By leveraging various statistical tools, health professionals can predict potential outbreaks, analyze ongoing situations, and devise effective responses to mitigate impact. For that to happen, there are a few possible stages of the analysis:
