概括

大多数呈阳性IgM测试的红疹报告都是错误的阳性,导致不必要的随访. 修订红疹病例定义对于准确的病例分类和有效的公共卫生监测至关重要.

科学领域:

公共卫生公共卫生
传染病流行病学传染病流行病学
临床诊断临床诊断临床诊断

背景情况:

红疹 (德国麻疹) 是一种可以通过疫苗预防的病毒感染.
美国红疹发病率低意味着许多阳性IgM测试可能是错误的阳性.
准确的病例分类对于有效的疾病监测至关重要.

研究的目的:

用IgM测试结果来评估红疹病例分类的准确性.
评估研究红疹阳性IgM测试所花费的时间.
确定当前红疹监测实践中的局限性.

主要方法:

从2018-2022年提交给加利福尼亚州公共卫生部 (CDPH) 的红疹报告进行了审查.
使用修改后的国家和领土流行病学家委员会 (CSTE) 病例定义.
调查了公共卫生工作人员,以估计报告后续工作所花费的时间.

主要成果:

在801个疑似红疹病例报告中,只有4个确诊病例.
58.3%的报告是错误测试,主要用于免疫查或错误测试.
大多数错误报告 (93.4%) 仅涉及阳性IgM测试结果.
调查疑似红疹报告平均花费3.2小时.

结论:

仅仅是阳性IgM测试结果对于分类红疹病例是不可靠的.
目前的监控实践导致大量资源被浪费,原因是错误的阳性结果.
红疹病例的CSTE定义需要修订,以便进行一致和准确的解释.

关键词:

Principles of Disease Surveillance

Principles of Disease Surveillance

Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...

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:
