Touch surfaces commonly found in hospital rooms, such as bed rails, call buttons, touch plates, chairs, door handles, light switches, grab rails, intravenous poles, dispensers (alcohol gel, paper towel, soap), dressing trolleys, and counter and table tops are known to be contaminated with "Staphylococcus", methicillin-resistant Staphylococcus aureus (one of the most virulent strains of antibiotic-resistant bacteria) and vancomycin-resistant "Enterococcus". Objects in closest proximity to patients have the highest levels of methicillin-resistant "Staphylococcus aureus" and vancomycin-resistant "Enterococcus". This is why touch surfaces in hospital rooms can serve as sources, or reservoirs, for the spread of bacteria from the hands of healthcare workers and visitors to patients.
