SARS-CoV-2 viral load and shedding kinetics

Nature Reviews Microbiology, 2022
SARS-CoV-2 viral load and detection of infectious virus in the respiratory tract are the two key parameters for estimating infectiousness. As shedding of infectious virus is required for onward transmission, understanding shedding characteristics is ...

Duration and key determinants of infectious virus shedding in hospitalized patients with coronavirus disease-2019 (COVID-19)

Nature Communications, 2021
Key questions in COVID-19 are the duration and determinants of infectious virus shedding. Here, we report that infectious virus shedding is detected by virus cultures in 23 of the 129 patients (17.8%) hospitalized with COVID-19.

Shedding light on the restart [PDF]

Physica Medica, 2020
Our reflection starts from basic considerations taken from the relevant literature, including in particular recent results about viral infection transmission and means to contain or eradicate it by UV–visible radiation as an effective antimicrobial agent [4], [5].

Molecular and serological investigation of 2019-nCoV infected patients: implication of multiple shedding routes

Emerging Microbes and Infections, 2020
In December 2019, a novel coronavirus (2019-nCoV) caused an outbreak in Wuhan, China, and soon spread to other parts of the world. It was believed that 2019-nCoV was transmitted through respiratory tract and then induced pneumonia, thus molecular ...

Shedding of infectious SARS-CoV-2 despite vaccination

PLoS Pathogens, 2022
The SARS-CoV-2 Delta Variant of Concern is highly transmissible and contains mutations that confer partial immune escape. The emergence of Delta in North America caused the first surge in COVID-19 cases after SARS-CoV-2 vaccines became widely available ...

The D614G mutation in the SARS-CoV-2 spike protein reduces S1 shedding and increases infectivity

bioRxiv, 2020
SARS coronavirus 2 (SARS-CoV-2) isolates encoding a D614G mutation in the viral spike (S) protein predominate over time in locales where it is found, implying that this change enhances viral transmission.

Transmission Potential of SARS-CoV-2 in Viral Shedding Observed at the University of Nebraska Medical Center

medRxiv, 2020
Lack of evidence on SARS-CoV-2 transmission dynamics has led to shifting isolation guidelines between airborne and droplet isolation precautions. During the initial isolation of 13 individuals confirmed positive with COVID-19 infection, air and surface ...

Factors associated with prolonged viral RNA shedding in patients with COVID-19

Clinical Infectious Diseases, 2020
Background An outbreak of coronavirus disease 2019 (COVID-19) is becoming a public health emergency. Data are limited on the duration and host factors related to viral shedding.
