Alcohol-based hand sanitisers were introduced in hospitals to stop the spread of drug-resistant superbugs like MRSA. Now it seems the bacteria have got the upper hand again
Bacteria triumph again. Superbugs have found a way to alter their genes to make it harder to kill them with alcohol-based hand sanitisers.
Alcohol-based hand sanitisers were widely introduced to hospitals in the early 2000s to stop the spread of drug-resistant superbugs like methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococcus (VRE) on people’s hands.
