Virology is the branch of biological sciences that investigates viruses and virus-like agents, encompassing their molecular structure, genome organization, replication strategies, evolution, and interactions with host cells and organisms. It integrates methods from molecular biology, genetics, biochemistry, immunology, and cell biology to elucidate viral entry, gene expression, assembly, egress, and mechanisms of pathogenesis. Virology also addresses virus classification, epidemiology, host range, and antiviral resistance, and underpins the rational design of vaccines, antiviral drugs, viral vectors for gene delivery, and oncolytic virotherapies, as well as biosurveillance and containment strategies for emerging and re-emerging viral diseases.
Researchers at the Helmholtz Institute for One Health (HIOH), a site of the Helmholtz Centre for Infection Research (HZI), together with an interdisciplinary team of partners, have identified the fire-footed rope squirrel ...
