概括
检测C型肝炎病毒 (HCV) 再感染对于预防传播至关重要. 这次审查发现,与男性发生性关系的男性 (MSM) 的HCV再感染率最高,并且与测试频率没有显著差异.
科学领域:
- 病毒学 病毒学
- 流行病学 流行病学
- 公共卫生 公共卫生
背景情况:
- 检测C型肝炎病毒 (HCV) 再感染对于控制传播至关重要,特别是在关键人群中.
- 了解SVR (持续病毒反应) 后的再感染动态对于公共卫生战略至关重要.
研究的目的:
- 系统地审查和确定SVR后后续测试间隔和HCV再感染检测之间的关联.
- 分析不同高风险人群和检测频率的HCV再感染发病率.
主要方法:
- 系统审查和随机效应观测研究的元分析.
- 搜索电子数据库 (2014年1月至2023年2月) 针对关键人群中HCV再感染发病率的研究,分离测试间隔.
- 根据人口和测试频率计算的聚合发病率估计.
主要成果:
- 包括41项研究 (9453人);38项纳入元分析 (8931人).
- 总体汇总的HCV再感染发病率为每100人年4.13 (py).
- 发病率因人群而异:PWID (2.84/100 py),MSM (7.37/100 py),监护环境 (7.23/100 py). 发生率有所不同. 测试间隔≤6个月显示的发病率略高 (4.26/100年) 比>6个月 (5.19/100年).
结论:
- 在MSM中,HCV再感染的发生率最高,与重新检测间隔没有明确的关联.
- 较短的测试间隔可能会增加再感染的检测,并防止进一步传播.
- 需要进一步的比较研究来确认全球HCV消除的最佳测试策略.

Retrovirus Life Cycles
46.1K
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...

Healthcare Associated Infections II: Preventive Measures
2.7K
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...
