10%

15%

The correct percentage of nosocomial infections attributed to bacterial contamination on the hands of healthcare workers is believed to be 15%. This statistic underscores the critical role that hand hygiene plays in infection control within healthcare settings. Effective hand hygiene protocols can significantly reduce the transmission of pathogens, thus preventing the occurrence of hospital-acquired infections.

Hand hygiene is essential because healthcare workers frequently come into contact with patients, medical equipment, and surfaces that may harbor infectious agents. The act of handwashing or using alcohol-based hand sanitizers effectively disrupts the transmission of bacteria and viruses.

While other percentages are also informative, the 15% figure specifically highlights the effectiveness of promoting stringent hand hygiene practices as a vital infection control measure in healthcare facilities.
