Does alcohol based rub kill all germs?

Alcohol-based hand rubs are effective at killing many types of germs, including bacteria and some viruses, but they do not eliminate all pathogens. They are particularly effective against enveloped viruses and certain bacteria, but may be less effective against non-enveloped viruses, spores, and some types of resistant bacteria. For optimal hygiene, it’s important to use alcohol-based rubs correctly and to complement them with handwashing when necessary.
