Remember the deadly "superbug"—multidrug resistant Staphylococcus aureus, or MRSA—that haunted people with HIV (and got mass media attention) a few years ago? An Atlanta Veteran's Affairs Medical Center study shows MRSA rates have subsided from their 2007 high.

An informal POZ poll found that HIV doctors elsewhere (including Barbara Zeller, MD, chief medical officer at HELP/PSI in the Bronx, New York; Loren Miller, MD, of Harbor-UCLA Medical Center David Geffen School of Medicine; and Richard Haubrich, MD, of University of California at San Diego) concur. Staph control techniques may be responsible for stemming the tide, so keep showering—and using your own towel—after your gym workout.
