Breaking the chain of infection does NOT include which of the following?

Breaking the chain of infection involves various strategies aimed at interrupting the transmission of infectious agents and minimizing the risk of infection. Each component of the chain must be addressed to effectively control and prevent infections.

Enhancing the immune system is crucial for an individual's health and can help fight off infections once a pathogen has entered the body, but it does not directly interrupt the chain of infection itself. Strategies such as preventing transmission (through practices like hand hygiene), eliminating microorganisms (via sterilization or disinfection), and supporting natural body defenses (such as through vaccinations) are all focused on reducing the likelihood that an infectious agent will be transmitted from one host to another.

Thus, while enhancing the immune system contributes to overall health and resistance to infections, it does not directly address the mechanisms of transmission or the presence of infectious agents in the environment, which are essential to effectively breaking that chain.
