Multi-drug resistant superbugs, which can cause dangerous infections, are becoming increasingly resistant to alcohol-based hand sanitizers and disinfectants, according to an Australian study.

Healthcare entities, including nursing homes, often use hand rubs and washes that contain alcohol in efforts to defeat superbugs such as VRE and MRSA.

Researchers found specific genetic changes over 20 years in VRE, and described the bugs as a “new wave of superbugs.”

Investigators findings were published in Science Translational Medicine.
