The Polio Wall of Fame (pictured) is a set of fifteen sculptured busts of 17 individuals who made important contributions to understanding and preventing poliomyelitis. The busts are mounted on an exterior wall of Founder’s Hall at the Roosevelt Warm Springs Institute for Rehabilitation in Warm Springs, Georgia, USA. In my laboratory we have a slightly different …
Two back-to-back papers were published last week that provide a detailed analysis of what it would take for avian influenza H5N1 and H7N9 viruses to switch to human receptors. Influenza virus initiates infection by attaching to the cell surface, a process mediated by binding of the viral hemagglutinin protein (HA) to sialic acid. This sugar …
Miravirsen is a drug that binds to and blocks the function of a cellular microRNA called miR-122 that is required for the replication of hepatitis C virus (HCV). Treatment of chimpanzees chronically infected with HCV with this drug leads to suppression of viral replication. The results of a phase 2b human clinical trial in HCV …

The spring semester has just ended at Columbia University, which means that my annual virology course has also concluded. The course met twice weekly, during which time we discussed the basic principles of virology, including how virions are built, how they replicate, and how they cause disease. For the last two lectures of the course …
There have been 131 confirmed human infections with avian influenza H7N9 virus in China, but so far there is little evidence for human to human transmission. Three out of four patients report exposure to animals, ‘mostly chickens‘, suggesting that most of the infections are zoonoses. Whether or not the virus will evolve to transmit among …

At the 2013 ASM meeting in Denver, Colorado, Stanley Maloy discussed human infections with avian influenza H7N9 virus with Ronald Atlas, Ph.D., University of Louisville, KY; Robert Webster; St. Jude’s Research Hospital, Memphis, TN; Albert Osterhaus; Erasmus Medical Center, Rotterdam, The Netherlands; and Carole Heilman, NIAID, NIH, Bethesda, MD.
