Officials of the National Hockey League and the general public may find it unexpected to see chipmunk-cheeked hockey stars who have contracted mumps. But to public health experts, an outbreak in this setting is not surprising, given the ages of the athletes and the conditions under which they play.
At least five NHL teams have reported 15 players who have contracted the mumps virus. The most high profile is Pittsburgh Penguins captain Sidney Crosby, captured in photographs with one swollen cheek. Late Tuesday, the Penguins confirmed forward Beau Bennett is also infected.
