What action must soldiers take after using the latrine to reduce germ spread?

Washing hands using soap and potable water is the most effective action soldiers can take to reduce the spread of germs after using the latrine. This practice is essential because handwashing with soap removes dirt, bacteria, and viruses that may be present on the hands, which can easily be transferred to food, equipment, or other individuals. Proper hand hygiene plays a critical role in preventing the spread of infectious diseases, especially in field environments where access to healthcare may be limited.

While applying hand sanitizer may be convenient, it is not as effective as washing hands with soap and water, particularly when hands are visibly soiled. Engaging in a physical workout or disposing of clothing items does not directly contribute to germ reduction and could divert attention from the important hygiene practice that handwashing offers. Thus, the correct practice prioritizes improving health outcomes in a practical way that is essential in field sanitation.
