概括

人类类型3型偏流感病毒 (HPIV-3) 在血液病学部门引起严重爆发,特别影响多发性骨髓瘤患者. 常规HPIV-3检测和加强感染控制对于预防至关重要.

科学领域:

传染性疾病传染性疾病
病毒学病毒学
流行病学流行病学

背景情况:

人类甲型流感病毒3型 (HPIV-3) 是已知的呼吸道感染和医院流行病的原因.
血液病患者,特别是多发性骨髓瘤患者,容易受到呼吸道感染的严重后果的影响.

研究的目的:

为了调查一个血液病学单位的HPIV-3疫情.
分析HPIV-3的临床特征,发病率和传播动态.
评估感染预防和控制 (IPC) 措施的影响.

主要方法:

多重PCR用于呼吸道病毒查.
在HPIV-3量化和全基因组测序方面.
临床数据收集和发病率计算.
用于病毒检测的空气采样.

主要成果:

在17.7%的血液病患者中检测到HPIV-3,其中80%患有多发性骨髓瘤.
与阴性患者相比,HPIV-3阳性患者的肺炎率 (60%) 和死亡率 (35%) 显着更高.
在空气中检测到HPIV-3,全基因组测序证实了单一的循环菌株.
加强的IPC措施成功制了疫情爆发.

结论:

在血液病患者,尤其是多发性骨髓瘤患者中,HPIV-3具有显著的流行风险.
在这个人群中,严重的HPIV-3感染,包括肺炎和增加的死亡率,很普遍.
常规的HPIV-3测试和强大的IPC在血液病学部门是必不可少的.

Viral Mutations

Viral Mutations

A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...
