The federal government is waking up to what has become a growing nightmare in many parts of the country _ a bed bug outbreak. The tiny reddish-brown insects, last seen in great numbers prior to World War II, are on the rebound. They have infested college dormitories, hospital wings, homeless shelters and swanky hotels from New York City to Chicago to Washington. (AP Photo/Tim McCoy, Virginia Tech Department of Entomology)
