Viruses are infectious units with diameters of about 16 nm (circoviruses) to over 300 nm (poxviruses; Table 2.1). Their small size makes them ultrafilterable, i.e. they are not retained by bacteria-proof filters. Viruses have evolved over millions of years, and have adapted to specific organisms or their cells. The infectious virus particles, or virions, are composed of proteins and are surrounded in some species of viruses by a lipid membrane, which is referred to as an envelope; the particles… Expand

Viral G-quadruplexes: New frontiers in virus pathogenesis and antiviral therapy
TLDR
This chapter presents the state of the art on the structural and functional characterization of viral G4s in RNA viruses, DNA viruses and retroviruses, and presents the G4 ligands that provide further details on the viral G 4 role and which, showing promising antiviral activity, could be exploited for the development of innovative antiviral agents.

Risk for Fomite-Mediated Transmission of SARS-CoV-2 in Child Daycares, Schools, Nursing Homes, and Offices
TLDR
It is found that fomites might be a substantial source of transmission risk, particularly in schools and child daycares, and combining surface cleaning and decontamination with mask wearing can help mitigate this risk. Expand
Risk of fomite-mediated transmission of SARS-CoV-2 in child daycares, schools, and offices: a modeling study
TLDR
It is found that fomites may be a substantial source of risk, particularly in schools and child daycares, and combining surface cleaning and decontamination with strategies to reduce pathogen shedding on surfaces can help mitigate this risk. Expand
