概括
大多数麻疹补充免疫活动 (SIA) 缺乏运动后覆盖率调查 (PCCS),尽管建议这样做. 当进行PCCS时,需要提高及时性和标准化报告,以便在消除麻疹的努力中更好地利用数据.
科学领域:
- 公共卫生 公共卫生
- 流行病学 流行病学
- 疫苗接种计划 疫苗接种计划
背景情况:
- 麻疹消除策略依赖于补充免疫活动 (SIAs) 来解决免疫缺口.
- 竞选后覆盖率调查 (PCCS) 对于评估SIA有效性至关重要.
- 本研究分析了最近的PCCS,以确定评估SIA覆盖面的挑战和优势.
研究的目的:
- 在最近的SIA之后进行的精选PCCS的特征.
- 确定PCCS实施和报告中的挑战和优势.
- 为改善PCCS及其数据利用提供建议.
主要方法:
- 从全球麻疹/MR SIA数据库中提取国家SIA数据 (2020-2023年).
- 审查了来自世界卫生组织的可用PCCS报告.
- 分析PCCS实施细节,包括抽样,实施者和关键发现.
主要成果:
- 自2020年以来,只有23%的国家AIS有可用的PCCS报告;所有这些来自Gavi资格国家.
- PCCS经常被推迟,在SIA的三个月内完成的不到一半.
- PCCS覆盖范围通常低估了行政数据;然而,许多PCCS成功报告了达到零剂量儿童.
结论:
- 在推的PCCS实施和遵循SIAs的实际实践之间存在很大的差距.

Steps in Outbreak Investigation
106
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:

Principles of Disease Surveillance
69
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...

Healthcare Associated Infections II: Preventive Measures
2.5K
Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Transmission-based Precautions II: Airborne and Protective Environment
1.2K
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...
