A recent study of electronic faucets at Johns Hopkins Hospital in Baltimore revealed that 50% of electronic faucets at the hospital had the legionella bacteria, versus only 15% from traditional faucets.  Ironically, electronic faucets are intended to allow hospital staff to turn water on and off without touching the faucet itself, thereby reducing the risk of bacterial transfer.  Researchers suspect the reason for this higher concentration of legionella bacteria in the electronic faucets is due to more surfaces in the electronic faucets to grow on, and are more difficult to clean. People contract Legionnaires’ disease from faucets when water coming from the faucet containing the legionella bacteria becomes aerosolized.
