Which of the following is NOT a method to reduce the risk of infection transmission?

Inadequate hand hygiene is a practice that increases the risk of infection transmission rather than reducing it. Proper hand hygiene, which includes regular hand washing with soap and water or the use of alcohol-based hand sanitizers, is a critical component of infection control protocols. It effectively removes pathogens from the hands, significantly decreasing the likelihood of spreading infections in healthcare settings and the community at large.

In contrast, vaccination is a preventive measure that helps protect individuals and populations from infectious diseases by triggering an immune response. Isolation of infected patients is another critical strategy that prevents the spread of infections by keeping those who are infected away from healthy individuals. Engineering controls refer to physical changes to the environment that reduce the risk of exposure, such as improved ventilation systems or safety devices for handling sharp instruments. All of these methods work towards minimizing the transmission of infections.
