Virology Lectures 2021 #12 - Infection Basics

We now move from explaining virus infection in cell culture to a discussion of viral pathogenesis, the process by which viruses cause disease. In this lecture we cover fundamental aspects of how viruses enter hosts, spread to and infect different tissues, transmission to new hosts, and how geography and season may affect virus infections.

– Who Am I? –

I’m Vincent Racaniello, Earth’s Virology Professor.

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 YouTube channel I share videos of my lectures, podcasts, and more.

New videos are uploaded multiple days a week.

Thanks a lot to make this public ...so many think YT is useless in transmitting education ...knowledge will save humanity,

[RiDankulous]

This is an excellent part of the course, thank you. I try to get through all the what I consider dense material but enjoy these more interesting episodes which interface more with my reality.

[stephsf]

Great lecture. Thank you. I promise never to walk without 🩴🐭🩴🐭🩴

As always, thank you for your updated lectures, Prof. Vincent!

Lots'a love, cheers, & Mabuhay, from tropical Philippines!

Great way of spreading knowledge globally, thank you so much. Makes you wonder why other scientific information is not spread in a similar way on the same platforms.

Thank you for this content. I really appreciate it.

I was searching this lectures for so long thanks it means a lot for me

I’ve been following your lectures for more than five years Prof. Rackiello, and learning a lot from you. As I noticed, you give much attention to using the accurate terminology there is a term in this lecture which is not used any more in the medical microbiology field. Nosocomial infections term is replaced currently with the hospital acquired infections (HAI). Please correct me if l’m mistaken. Dr Alqurashi

Dear Prof. Racaniello, my playlist “Shorts with Mr. Covid” is a small contribution to the much-needed effort in Virology education. Since I teach behavioral neuroscience and not virology, would you mind if I link to your videos in the playlist? I wish all my students also take your course! Best wishes, Emanuel 👍.

On emerging viruses....i have a question...spill over happens as an evolutionary mater...virus tries...fail..try again ...fail again until makes it!!! That means the serology of population wil be changing... or not? If so survey of blood banks and archive samples may provide info.... on NipahVirus spill over are there any serology survey or publications?

‘Today people being very sensitive about naming viruses” is a huge understatement. This hyperactive politically correct cancel culture is perhaps the lowest point in our recent history that has tainted media, politics and sadly science too.

For the CFR=10000/50000 20% (not 25%)?

Well another lecture enjoyed thank you ! I would love to know if we have any studies with sars cov-02 the way that those students studied confirmed influenza cases in the 1 ft cone ? why would there not be a more recent study with confirmed Sarscov2 infection ? Can we measure sars cov2 in the sneezes or are they just pictures of people sneezing ? lol

I'm really trying to understand virology, in those pictures of measles and Coronavirus pictures, I noticed coronavirus in the measles picture and measles virus in the coronavirus picture.
How do you understand which one is more daminant in a host if the genetic material you sampled is not necessarily where the virus reproduction is happening ? So many questions, I feel like this branch of science is attempting to map an infinitely large labyrinth..that would take infinite manpower infinite years....just sayin...
