Why are viruses often described as nothing more than genes in a box?
In short: Viruses pose a constant threat to human health, from seasonal flu to COVID-19. This video explains the biological nature of viruses, how they hijack cells to spread, and the mechanisms by which vaccines and antiviral medicines empower our immune systems to defend against them.
Viruses function essentially as genetic material encased in a protective structure, often described as genes in a box. The video examines their evolutionary origins and the specific ways they invade host cells to replicate and propagate.
Beyond the mechanics of infection, the episode explores how medical interventions like vaccines and antivirals assist the body in fighting off these pathogens. It also features insights from Dr. Quarraisha Abdool Karim regarding the development and application of antiviral treatments.
