A worker from the Richardson Independent School District reaches for a mask before going in to disinfect Canyon Creek Elementary School, which was shut down after one case of swine flu was confirmed yesterday, in Richardson, Texas April 28, 2009. New swine flu infections were found around the world on Tuesday and the specter of a pandemic began to hit the travel industry as governments warned people to stay away from Mexico where 149 people have died.
