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 outer - layer of bacteria and washing for at least 20 seconds ensures most bacteria are removed. Washing with water only is less effective, handling food without washing hands spreads bacteria, and 5 - second soap wash is too short.

Answer:

Wash hands with soap for at least 20 seconds.
