Citando:
"On each day, over 12 weeks, levels of bacterial contamination in the toilets were measured, allowing comparisons to be made when either paper towels or jet-air dryers were in use. Samples were taken from the floors, air and surfaces in each of the toilets.
The main target bacteria were:
Staphylococcus aureus: responsible for a range of conditions from minor skin and wound infections to life-threatening septicaemia.
Enterococci: bacteria that can cause difficult-to-treat infections, including in immunocompromised patients.
Enterobacteria: including Escherichia coli. These bacteria cause a wide range of infections, including gastroenteritis, pneumonia and septicaemia.
Across the three hospitals, bacterial counts were significantly higher in the toilets on the days that jet-air dryers were in use.
In Leeds and Paris, at least five times more bacteria were recovered from the floors when jet-air dryers were in use, compared with paper towels."
