SPREADING THE FLU

摘要

Even a pandemic can have a silver lining. Aflood of visitors to an Irish exhibition about epidemics has become a mother lode of data on the spread of disease.rnOn 17 April, the Science Gallery at Trinity College Dublin launched an exhibit called INFECTIOUS. To give visitors a firsthand feel for "epidemic processes," everyone gets a radio-frequency identification tag. Tags are initially "uninfected" but can get "infected" by proximity to "infected" staff or visitors. A computer tracks everyone, mapping the spread of the infection.
