Poor hygiene practices in hospitals may lead to antibiotic resistance

Poor hygiene practices in hospitals may lead to antibiotic resistance

A new paper in Evolution, Medicine, and Public Health, published by Oxford University Press, indicates that antibiotic resistance may result from poor hygiene practices in hospitals or other medical facilities. Proper hand hygiene in clinical work is a cornerstone of patient safety, but compliance is still poor. This is even though hand hygiene is simple, … Read more
