Antigenic variation is a hallmark of influenza virus that allows the virus to evade host defenses. Consequently influenza vaccines need to be reformulated frequently to keep up with changing viruses. In contrast, antigenic variation is not a hallmark of poliovirus – the same poliovirus vaccines ... Read More
In the spring of each year I teach a virology course to undergraduates and masters students at Columbia University. I produce video recordings of all my lectures not only for students in the course, but for anyone else who is interested in learning about viruses.

Virologist Hilary Koprowski died on 11 April 2013 at the age of 96. His main accomplishments are nicely summarized in the New York Times, but for a more comprehensive overview of his life, I highly recommend his biography Listen to the Music by Roger Vaughan. I did not have many opportunities to... Read More
Did you ever wonder what different virus infections you have had in your lifetime? Now you can find out with just a drop of your blood and about $25.
Immune defense systems of many hosts produce antibodies in response to virus infections. These large proteins, which are generally virus specif... Read More
Popular Science has just launched a new science blogging network with 13 blogs. Among them are two that have a focus on microbiology, Under the Microscope by JA Tetro and Our Modern Plague by Brooke Borel. Each blog has an inaugural post that outlines the author's vision for future subject matte... Read More

The 1918 influenza pandemic was particularly lethal, not only for the very young and the very old (as observed for typical influenza), but unexpectedly also for young adults, 20 to 40 years of age (pictured). It has been suggested that the increased lethality in young adults occurred because the... Read More
Given the extent of the Ebola virus outbreak in West Africa, transport of an infected individual to the US was bound to happen. The case is an adult who had contact with an Ebola virus-infected woman in Liberia, then traveled to Dallas. He had no symptoms before arriving in the US and therefore ... Read More

An interesting recent paper characterizing the fungal microbiome ("mycobiome") of human skin. It would be lovely if the TWIM crew could discuss this in an upcoming episode!
"Traditional culture-based methods have incompletely defined the microbial landscape of common recalcitrant human fungal... Read More
This week’s virology question comes from Eric, who writes:
I’m working on an MPH and in one of my classes we are currently studying the influenza virus. I’d forgotten that the genome is in 8 separate parts. Curious, I’ve been searching but can’t find any information as to why that is?
What... Read More
In this blog entry, I discuss a talk I attended at ASMCUE about "Citizen Science" and how some of my own work appeared in that talk! It is a vital that we scientists explain not just what we do, but why it is so fascinating to us...by involving the public! Read More
The coronavirus responsible for Middle East Respiratory Syndrome (MERS) is prevalent in camels throughout Saudi Arabia and has been around for at least 20 years, according to a study to be published in mBio®, the online open-access journal of the American Society for Microbiology.
