What is the most common means of spreading infection in healthcare settings?

• A. Air currents
• B. Environmental surfaces
• C. Human hands
• D. Insect vectors

Answer: (C)

The main idea here is that the hands of healthcare workers are the primary route by which infections are transmitted in healthcare settings. When hands touch a patient, a wound, or contaminated equipment or surfaces, pathogens can hitch a ride and be passed to another patient or to the caregiver themselves. Because hand-to-hand and hand-to-surface contacts happen frequently during routine care, this route accounts for most healthcare-associated infections. That’s why hand hygiene—using soap and water or an alcohol-based hand rub—along with proper use of gloves and adherence to standard precautions, is the cornerstone of infection prevention. Air currents and aerosols can spread certain infections, and contaminated environmental surfaces can harbor organisms, but those pathways become most problematic when hands fail to transfer those organisms between patients or between a patient and a surface. Insect vectors are not a common concern in typical healthcare settings.
