TWiV 9: Fever! The discovery of Lassa virus

November 22, 2008

Fever! Hosts: Vincent Racaniello and Dickson Despommier

Vincent and Dick recall the discovery of Lassa virus in Africa in 1969. A non-fictional account of the story, ‘Fever’, written by John G. Fuller and published in 1974, inspired Vincent to become a virologist. Part of the story took place at Columbia-Presbyterian Hospital (now Columbia University Medical Center), where both Vincent and Dick are employed. Dick remembers many of the key players in this medical drama.

An article on how World of Warcraft became a model for the transmission of virus infections was published in Lancet Infectious Diseases. The title of the article is “The untapped potential of virtual game worlds to shed light on real world epidemics.”
After we did the netcast we learned of a game for the iPhone called ‘Virus’. In this game your body is infected with a virus, and you must clear the infection by controlling white blood cells. The game is at the iTunes App store.
