1. Hand

2. Standard

3. Listening

4. Transmission

The correct answer is: Hand

Hand hygiene is the single most important method of preventing the spread of infection because it effectively removes germs and bacteria from the skin. Proper handwashing with soap and water, or using hand sanitizer, significantly reduces the risk of transferring pathogens from one surface or person to another. This practice is crucial in both healthcare settings and everyday life, as it serves as the primary defense against infections, especially in environments where individuals are in close contact or where there is a higher likelihood of exposure to infectious agents. While other types of hygiene, like standard hygiene practices or transmission precautions, play important roles in infection control, none are as universally effective as proper hand hygiene in breaking the chain of infection.
