Which action is most effective in preventing the spread of infection?

• A. Wearing gloves
• B. Breaking one of the chains of infection
• C. Administering antibiotics
• D. Increasing visitor access

Answer: (B)

Breaking one of the chains of infection is a fundamental strategy in infection control. The chain of infection consists of several components: the infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host. By disrupting any link in this chain, the possibility of infection transmission is significantly reduced. For instance, if the mode of transmission is broken by practicing proper hand hygiene, the risk of spreading pathogens diminishes. Wearing gloves, while protective, only addresses a specific aspect of infection control without breaking the chain entirely. Administering antibiotics can help treat existing infections but does not prevent the initial spread of infection. Increasing visitor access does not contribute to infection control and can actually heighten the risk of transmission by increasing the number of individuals in a susceptible environment. Thus, breaking one of the chains of infection is the most comprehensive and effective method for preventing the spread of infection.
