When were universal precautions introduced?

• A. 1960s during the polio era
• B. 1970s during the chemical hazard period
• C. 1980s during the HIV/AIDS epidemic
• D. 1990s during the MRSA emergence

Answer: (C)

Universal precautions were introduced in the mid-1980s in response to the HIV/AIDS epidemic. The CDC published guidelines around 1985 to protect healthcare workers by treating all human blood and certain body fluids as potentially infectious and requiring protective barriers, proper hand hygiene, safe needle practices, and safe handling of sharps. This approach aimed to reduce transmission of HIV, HBV, and other bloodborne pathogens in clinical settings. The concept later evolved into standard precautions in 1996, broadening the scope to include all body fluids and non-contact exposures. The other time frames don’t align with this policy shift, which was driven by the HIV/AIDS crisis rather than polio campaigns, chemical hazard regulations, or MRSA emergence.
