Some bacteria have become resistant to hand sanitizers

The video discusses the effectiveness of alcohol against bacterial infections, highlighting a study that observed increased alcohol tolerance in enterococcal bacteria over time. Researchers analyzed bacteria from 1997 to 2015, finding that post-2009 strains were more tolerant to alcohol than pre-2004 strains. Further tests showed that alcohol-tolerant bacteria persisted in mice even after cleaning with sanitizing wipes.
