A drug-resistant bacterium called MRSA has recently claimed the life of a 17-year-old student in Virginia. The so-called "superbug" causes potentially life-threatening bloodstream infections. A recent study in The Journal of the American Medical Association warns that the infectious strain is becoming more common.
Dr. Elizabeth Bancroft, a medical epidemiologist at the Los Angeles County Department of Public Health, answers questions about the drug-resistant bacteria. She is author of the JAMA article, "Antimicrobial Resistance: It's Not Just for Hospitals."
