Crossover study with 50 Health care workers using each product with a minimum of 3 days in between. Products will be applied twice as per manufacturer's instructions for a Healthcare Personnel Handwash followed by immediate hand print. Persistent hand prints will be collected after exposure to environmental contaminants in the common areas. Hand prints will also be collected from one hand of 60 patients cared for by a participating Health Care Worker and gloved hand of Health Care Worker. All media contain neutralizers to inactivate active ingredients in each product and on surfaces. Each hand print plate's area of growth will be measured for Colony Forming Units using computerized software.
