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.
When a rare but deadly rodent-borne virus struck passengers on a cruise ship and seemed to be spreading, there were no treatments for those who fell ill and no vaccines to protect others.
