How can personal protective equipment (PPE) reduce infection risk?

Personal protective equipment (PPE) plays a crucial role in infection control by providing a barrier against pathogens. This barrier prevents the transmission of infectious agents from one person to another, particularly in environments where exposure to blood or other bodily fluids is a risk. For example, gloves, masks, gowns, and face shields are designed to shield healthcare workers and individuals from direct contact with potentially infectious materials. By creating this protective layer, PPE significantly reduces the likelihood of pathogen entry into the body, thereby lowering the risk of infection.

Other options do not accurately reflect the role of PPE. While effective in providing protection, it does not eliminate the need for hygiene practices, which remain essential for comprehensive infection control. Additionally, PPE is not exclusively for chemical exposure; it is primarily used to manage biological hazards. Finally, while PPE is effective, it does not guarantee complete immunity to infections—proper use and continual adherence to safety protocols are equally important in minimizing risk.
