概括

麻疹病毒 (MPXV) 类 Ib 的平均潜伏期为 13.6 天,可能因传播途径而异. 这一发现影响了全球监测和预防mopox疫情的预防建议.

科学领域:

流行病学流行病学
传染性疾病传染性疾病
病毒学病毒学

背景情况:

莫普克斯病毒 (MPXV) 类别Ib于2023年9月在刚果民主共和国出现,导致国际传播和世卫组织紧急声明.
关于MPXV类 Ib的潜伏期的数据有限,这对于了解疫情动态和应对策略至关重要.

研究的目的:

为了估计mopox clade Ib. 的潜伏期.
根据暴露途径和人口因素,调查潜伏期的潜在差异.

主要方法:

对临床监测数据的贝叶斯分析.
这些数据是从2024年6月至10月期间在刚果民主共和国南基武省从临床上接受治疗的个人中收集的,这些人已确认感染了mopox clade Ib感染.
分析包括人口特征,暴露史,症状发作和传播途径.

主要成果:

在37例高病毒载量确诊病例中,暴露于皮疹的中位潜伏期为13.6天 (95%CRI,9.6-19.0天).
估计的潜伏期从3.1天 (第5百分位数) 到32.3天 (第95百分位数) 之间.
与非性传播 (13.5天) 相比,在性传播 (10.3天) 中观察到较短的平均潜伏期,尽管可信的间隔重叠.

结论:

MPXV 类 Ib 可能比其他 MPXV 类表现出更长的潜伏期,变化取决于传播途径.
与性传播相关的更短的潜伏期与在IIb类爆发中观察到的模式一致.
结果为暴露后监测和预防期的全球建议提供了信息.

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...

Retrovirus Life Cycles

Retrovirus Life Cycles

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...
