SOUTHAMPTON, England, May 29 (UPI) -- Copper and copper alloys destroy norovirus -- an infectious "vomiting" bug that sickens more than 267 million people worldwide, British researchers say.
Lead researcher Bill Keevil of the University of Southampton said the norovirus causes acute gastroenteritis -- stomach flu -- and it is spread via contaminated food or water, person-to-person contact and from touching contaminated surfaces.
