Virology Lectures 2024 #22: Emerging Viruses

An emerging virus is a newly discovered virus or viral disease, or a different disease caused by a known virus. In this lecture we discuss the anthropogenic factors that drive virus emergence, the four types of virus-host interactions, and descriptions of specific emerging virus infections including those caused by poliovirus, Nipah and Hendra viruses, Junin virus, Ebolavirus, and the coronaviruses SARS-CoV, MERS-CoV, and SARS-CoV-2.

- Who Am I? -
I’m Vincent Racaniello, Earth’s Virology Professor, and I believe that education should be free.
I’m also a professor of virology at Columbia University in New York. I’ve been doing research on viruses since 1976, and teaching virology in classrooms and online since 1999. On this RUclips channel I share videos of my lectures, podcasts, and more.
New videos are uploaded several times each week.
I do not run ads on our work as it is disruptive to learning. We depend on your support.

This is such a great video Vincent. I've been a giant fan of MicrobeTV and the people that are involved since discovering you folks in '20. I encourage everybody else who got thrust into this world of virology in that time start to build a basic level of knowledge in the subject with the amazing body of work that Vincent and folks have put together.

the virology lectures are great! so much information. the slides are condensed and plenty, with excellent illustrations from the book. thank you, vincent!

I can't get over the fact that "Muerto Canyon" residents objected to giving the name to the virus... the name is actually perfect, and it's way too late to avoid the association with negative things when you have "dead" in the name of your town.

[@tomsteinberg8106]

Wording of the Measles part seems confusing -- cattle domestication timing should be corrected. Cattle have been domesticated for millennia. Measles emergence in ~ 1000 CE is reasonable on the basis of historical description. (recent estimates vary, with a mean of ~ 530 BCE; SCIENCE, 2020,V 368, pp 1376-70)

Very good

Question from Calgary, Alberta, Canada: If humans stopped raising animals to eat and we all went vegetarian or ate Synthetic Food would this help stop the Plagues?

[@rouxbe3595]

Raising animals to eat (or capturing/killing wild animals) is only one of the many ways evolving viruses are introduced into humans. Epidemics and pandemics began with the domestication of PLANTS and animals because we began living in larger communities of people (villages & cities rather than small bands of hunter-gatherers).
We ate wild meat before domestication of plants & animals, but could only transmit viruses human-to-human to our own little band of hunter-gatherers.
If we were all vegans or ate synthetic food, we would still be deforesting for plant agriculture, thereby coming into contact with new viruses. Human activity in environments previously not populated by humans (i.e. deforestation of the Amazon, Malaysia, etc) exposes us to zoonotic viruses, but density of human populations in cities, and the ease/speed of worldwide travel allows viruses to become pandemics.

[@traianliviudanciu8665]

No
New viruses can emerge from melting permafrost,from humans and from labs,

[@marklemont3735]

Mosquitoes carry viruses and so do rodents, too.

[@marklemont3735]

Ticks, too!

[@troruaz]

virus transmission through all the ways is with us forever, thus potential for plagues will always be a possibility. I'd be happy if what you propose happened just for the sake of farmed animals and having to cull thousands/millions of them when due to virus exposure that they had nothing to do with (mad cow, H5N1 in chickens, etc)

Can putting raw milk on cereal cause a cereal infection?

[@charliemurphy1679]

Gotta go see the cerealogist

[@yakhoubakane452]

I like it!

[@emom358]

And now pig kidneys for transplant.
