What does the 'chain of infection' describe?

The 'chain of infection' describes the process by which infections are transmitted, highlighting the interconnected steps that need to occur for an infection to spread. This concept includes various elements such as the infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host. Understanding this chain is crucial for implementing effective infection control measures in healthcare settings to break the chain and prevent the spread of infections. Each component of the chain must be addressed to effectively manage and control outbreaks, making it essential knowledge for a Central Sterile Processing Technician and other healthcare professionals involved in patient care and safety.
