概括

该研究表明,SARS-CoV-2 (严重急性呼吸系统综合征冠状病毒2) 感染的发病率与流感相似,但住院率较低,这表明过渡到严重程度降低的流行病状态. 这种演变表明,COVID-19的未来影响力较小.

科学领域:

流行病学流行病学
传染病的动态传染病的动态.
公共卫生公共卫生

背景情况:

考虑了SARS-CoV-2的三种潜在的流行后轨迹:持续的严重程度,类似流感的严重程度,或过渡到流行性与降低的发病率.
了解SARS-CoV-2的未来演变对于公共卫生准备和应对策略至关重要.

研究的目的:

通过将其严重程度和住院率与流感相比较,评估SARS-CoV-2流行病的潜在演变.
为了评估SARS-CoV-2对抗病毒疗法的反应,与流感相比.

主要方法:

利用了美国国家Covid队列协作,CDC COVID-NET,CDC Fluview和废水SCAN仪表板的2021-2022年期间的数据.
使用电子健康记录对SARS-CoV-2,流感和对照对象进行量化病毒特异性发病率.
通过将国家数据与废水病毒基因拷贝度相关联,估计住院率的演变.

主要成果:

接受医疗治疗的SARS-CoV-2感染的发病率与流感相当.
当针对废水中的病毒度进行调整时,SARS-CoV-2住院率明显低于流感.
SARS-CoV-2 对抗病毒治疗的反应更为有利.

结论:

这些发现支持SARS-CoV-2发病率的快速下降.
数据表明,SARS-CoV-2向特有状态过渡,其特征与其他常见的人类冠状病毒相似.

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...

Viral Recombination

Viral Recombination

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.

Stages of Infection

Stages of Infection

Stages of infection describe what happens to a susceptible host once a pathogen invades the human body. The stages of infection are incubation, prodromal, illness, stage of decline, and convalescence. The incubation stage is the period from exposure to a pathogen until symptoms start. The infected person is unaware of impending illness as the pathogens grow and multiply within the body. The duration may vary depending on the type of infection. The incubation period of measles averages ten to...
