WASHINGTON - A germ that usually causes pimples or skin rashes caused fatal pneumonia in at least 24 otherwise young and healthy people during the 2006-2007 flu season and doctors need to watch for it, U.S. researchers said.
Many of the cases were caused by a drug-resistant form called methicillin-resistant Staphylococcus aureus or MRSA, the team led by the U.S. Centers for Disease Control and Prevention said Tuesday.
