On a person’s hand, there can be 300,000-500,000 genetically distinct bacteria at one time. wendy regularly puts hand sanitizer on because she is nervous about getting sick. the hand sanitizer kills 99% of these bacteria, but about 3,000-5,000 bacteria are left that are genetically resistant to the hand sanitizer.

Regarding what is written, it would be considered true if the antibacterial soap used has the real capacity to kill 99.9% of bacteria.

If so, it should be clarified that 1 of the resistant bacteria will survive hand washing, so it cannot be considered as sterilization.

Explanation:

The bacteria that survive, which would be 1% are considered to be the most pathogenic bacteria, which is why it may be that if Wendy continues having this habit, the health of her hands will worsen since she may suffer from opportunistic infections or possible dermatitis.
