概括

在维罗纳的6名患有呼吸道症状的儿童中检测到C105型肠道病毒 (EV-C105). 这项研究表明,EV-C105的发病率可能被低估了,这凸显了进一步调查的必要性.

科学领域:

病毒学病毒学
流行病学流行病学
基因组学就是基因组学.

背景情况:

肠道病毒 (EV) 感染很常见,特别是在儿童群体中.
监测特定的EV类型,如EV-C105,对于了解它们的流行病学至关重要.
之前关于EV-C105发病率的数据有限.

研究的目的:

描述维罗纳地区肠道病毒 (EV) 病例的局部发病率.
为了描述检测到的EV-C105菌株的基因组特征.
为了调查潜在的EV-C105感染集群.

主要方法:

从2022年9月到2024年9月对EV感染的流行病学调查.
常规分子测试用于EV检测.
桑格测序和全基因组测序 (WGS) 用于基因组表征.
计算EV阳性率和遗传学分析.

主要成果:

在2023年3月至5月期间,确定了6例患有上呼吸道症状的EV-C105儿童病例.
大多数 (96%) EV阳性结果来自呼吸道样本.
遗传学分析揭示了一个独特的EV-C105菌株集群,与欧洲血统病毒具有高核酸相同性.
鼻病毒占呼吸道病毒类型的90%,EV占9%.

结论:

确定的EV-C105群体表明,其发病率可能高于此前估计的.
这项研究提供了维罗纳地区EV-C105的初始基因组和流行病学数据.
需要进一步的大规模,多实验室的调查来确认EV-C105.5的流行率.

Transmission-based Precautions I: Contact, Enteric, and Droplets

Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
Contact Precautions:
Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...
