TED-Ed: 3 ways to end a virus | TED-Ed

The video explores the dynamics of virus variants, focusing on how Delta outcompeted Alpha. It explains three main ways viruses can go extinct: running out of hosts, being eliminated by vaccines, or being outcompeted by other strains. The video also discusses virus coexistence and niches, using examples like influenza and norovirus. Finally, it speculates on the future of SARS-CoV-2, considering the challenges of driving it to extinction due to animal reservoirs and current vaccine limitations.

What role do ecological niches play in the survival of different viral species?

What are the potential outcomes for SARS Co V2 as new variants arise?

What challenges exist in driving SARS Co V2 to extinction compared to smallpox?
