Today, Explained How will coronavirus end?
Feb 6, 2020
Dr. Vineet Menachery, a researcher at the University of Texas Medical Branch, sheds light on the complexities of coronaviruses. He discusses how a SARS-like virus could easily jump to humans, emphasizing the implications of wet markets and wildlife interactions. Menachery outlines three potential outcomes for the pandemic, evaluating public health strategies and natural virus dynamics. He also highlights the importance of preparedness for future outbreaks, urging vigilance in the face of global connectivity and environmental changes.

Episode notes
SARS Origin
- In 2002-2003, a SARS outbreak, originating from wet markets in Southeast Asia, caused over 8,000 cases and nearly 800 deaths worldwide.
- Civet cats and raccoon dogs in these markets harbored a virus almost identical to the SARS virus infecting humans.
SARS Mutation Theory
- Initially, scientists believed SARS resulted from a rare mutation in bat coronaviruses that allowed human infection.
- Later research revealed that some bat coronaviruses could infect human cells without adapting, challenging the rare mutation theory.
Bat-to-Human Transmission
- Research from 2013-2015 identified SARS-like viruses in bats that could infect human cells without adaptation.
- This discovery suggested that the potential for bat-to-human transmission was greater than previously thought.
