Which statement is NOT a link in the chain of infection?

Understanding the chain of infection means recognizing the sequence that allows a pathogen to spread: the causative agent (the pathogen) must have a reservoir, a portal of exit to leave that reservoir, a mode of transmission, a portal of entry to reach a new host, and a susceptible host. Hand hygiene isn’t a link in this chain; it’s a preventive action that interrupts transmission. By cleaning hands, you remove or kill many pathogens and prevent their transfer to patients or surfaces, effectively breaking the link between exit and entry. The other items—causative agent, reservoir, and portal of exit—are actual components of the chain that must exist for transmission to occur.
