I’m looking at a multiple-choice question on infection control in a postoperative ICU setting where multiple patients developed wound infections, likely due to cross-infection. The best prevention method is proper hand washing, not prophylactic antibiotics or fumigation. Citing the WHO guidelines on hand hygiene, it's clear that practicing hand hygiene is crucial to prevent the spread of nosocomial infections. I’ll gather relevant articles to support this and provide concise reasoning.
