Question

what is the best approach to prevent the spread of a bacterial infection?
wash hands with soap for at least 20 seconds.
wash hands with water only.
handle food without washing your hands.
wash hands with soap for five seconds.

Explanation:

Soap helps break down the lipid - based outer layer of bacteria, and washing for at least 20 seconds ensures thorough removal. Washing with water only is less effective as it doesn't disrupt bacterial structures as well. Handling food without washing hands spreads bacteria, and washing for only five seconds is too short for proper cleaning.

Answer:

Wash hands with soap for at least 20 seconds.
