What is a primary method by which germs are transmitted?

People's hands are a primary method by which germs are transmitted because they frequently come into contact with various surfaces and objects that may harbor pathogens. The hands can pick up germs from contaminated surfaces, respiratory droplets, or personal contact with infected individuals. Once the hands are contaminated, they can easily transfer these germs to other surfaces, food, or directly to other people through touch. This method of transmission is particularly significant in healthcare settings, where healthcare workers' hands are often the means by which infections spread from one patient to another.

While airborne particles, direct contact with surfaces, and water contamination are also methods of germ transmission, hands serve as a critical intermediary that can facilitate the spread of infections in a variety of environments. This highlights the importance of hand hygiene in infection control practices, particularly in nursing and healthcare.
