概括

儿童呼吸道同胞性病毒 (RSV) 病例数量的增加很可能是由于更多的测试,而不是病毒传播的增加. 这挑战了"债务豁免"理论,并强调了动态监控需求.

科学领域:

儿童传染病儿童传染病
流行病学流行病学
病毒学病毒学

背景情况:

在COVID-19大流行期间,呼吸道同胞性病毒 (RSV) 循环减少.
随后观察到RSV病例的复苏,导致RSV病例的复苏.
豁免权债务豁免权债务
这是一个假设,表明易受影响的儿童人口增加.
改变诊断实践在这种感知激增中的作用仍然不清楚.

研究的目的:

评估改变检测实践对观察到的呼吸道同胞病毒 (RSV) 病例数量和患者人口统计学的影响.
评估疫情期间RSV疾病严重程度的变化 (住院治疗,重症监护,机械通风).

主要方法:

在美国32家儿科医院 (2013-2023) 进行了342,530次RSV接触和980,546次RSV诊断测试的多中心追溯分析.
间断时间序列分析,以评估RSV患者和测试量中的流行病相关变化.
在病例数和患者年龄中,由于测试的变化而导致的轮班比例的量化.

主要成果:

与大流行前水平相比,2021-2023年,RSV患者数量增加了2.4倍,RSV测试数量增加了18.9倍.
患者体积和年龄分布的变化主要归因于诊断测试的增加.
需要住院,重症监护或机械通风的患者比例在所有年龄组显著下降.

结论:

从2021-2023年观察到RSV病例数量的增加可能是由于诊断测试的激增,不一定是病毒循环增加.
这些发现需要重新评估该研究的结果.
豁免权债务豁免权债务
一个假设. 假设.
动态监控策略必须考虑到测试分母的变化.

Rous Sarcoma Virus (RSV) and Cancer

5.1K

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand RNA genome. Its genome consists of four main open...

Viral Recombination

23.4K

Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.
