Question

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

Explanation:

Soap helps break down dirt and bacteria. Washing hands for at least 20 seconds ensures thorough removal of bacteria. Washing with water only or for too short a time (like 5 seconds) may not effectively remove bacteria. Handling food without washing hands spreads bacteria.

Answer:

Wash hands with soap for at least 20 seconds.
