New guidance from the Centers for Disease Control and Prevention (CDC) supersedes previous CDC guidance for both seasonal influenza and the Interim Guidance on Infection Control Measures for 2009 H1N1 Influenza in
Healthcare Settings which was written to apply uniquely to the special circumstances of the 2009 H1N1 pandemic as they existed in October 2009. As stated in that document, CDC planned to update the guidance as new information became available. Health Care Personnel refers to all persons, paid and unpaid, working in healthcare settings who have the potential for exposure to patients and/or to infectious materials, including body substances, contaminated medical supplies and equipment, contaminated environmental surfaces, or contaminated air.
