Infection control refers to methods used to eliminate or reduce the transmission of infectious organisms. Which choice best completes this statement?

• A. Removing visible dirt only
• B. Treating infections after they occur
• C. Preventing spread by hygiene, sterilization, and barriers
• D. Isolating patients without hygiene measures

Answer: (C)

Infection control focuses on stopping germs from moving between people by putting preventive practices in place. The best approach includes good hand hygiene, proper sterilization or disinfection of instruments, and barriers like gloves, masks, and protective gear to block transmission pathways. Cleaning visible dirt alone misses many microorganisms and won’t prevent spread. Treating infections after they occur is reactive rather than preventive, so it doesn’t reduce transmission. Isolating a person without implementing hygiene measures still leaves ways for germs to pass between people. By combining hygiene, sterilization, and barriers, you create a proactive, comprehensive defense against transmission.
