Virology is the scientific discipline concerned with the study of the biology of viruses and viral diseases, including the distribution, biochemistry, physiology, molecular biology, ecology, evolution and clinical aspects of viruses.
Age is the single greatest risk factor driving mortality after encounter with SARS-CoV-2. A new study shows that the composition of nasal epithelial cells varies across ages, facilitating SARS-CoV-2 growth and spread in older people.
Population mobility is associated with SARS-CoV-2 transmission but its impacts on other respiratory viruses are not well understood. Here, the authors investigate associations between mobile phone-derived mobility metrics and the dynamics of 18 respiratory viruses in Seattle, Washington from 2018 to 2022.
Here, Murray-Nerger et al use a genome-wide CRISPR/Cas9 screen to show that the nuclear protein SFPQ suppresses lytic reactivation of Epstein-Barr virus by promoting the expression and accumulation of linker histone H1 on the viral genome.
Enteroviruses are responsible for several human diseases without treatment. This study describes the molecular interactions between SETD3, actin, and viral 2A in viral replication, providing a framework for the development of host-targeted therapies against enteroviruses.
Contact patterns influence the spread of infectious diseases, but mathematical models of epidemics typically only account for age differences in contacts. Here, the authors investigate the importance of other sociodemographic characteristics in shaping contact patterns and vaccine uptake using survey data from Hungary.
In a serological analysis, Bore et al. utilise serum samples, collected from a cohort of individuals associated with bushmeat hunting and butchering, in the forested region of Guinea, a region close to the epicentre of the 2013–2016 West Africa Ebola virus disease epidemic.
Mice lacking A Disintegrin and Metalloproteinase 9 (ADAM9) do not mount Type 1 interferon responses against encephalomyocarditis infection. Here, Bazzone et al show that ADAM9 regulates innate immune responses via by MDA5.
In this study, Zhang et al. report that a bacterial symbiont residing in the gut of Aedes albopictus mosquitoes protects them from flavivirus infection.
