The Louisiana Department of Health (DHH) Office of Public Health (OPH) has created this Pandemic Influenza Guidance as a comprehensive containment and treatment plan to assist in the control of an outbreak of a novel influenza virus, such as the 2009 H1N1 influenza virus ("swine flu") or avian influenza. LDH OPH has followed, and will continue to follow, the international and national recommendations for identification, prophylaxis, and treatment of disease as well as considered the frameworks provided by the Centers for Disease Control and Prevention (CDC) for pandemic planning purposes as well as those recommended by the Occupational Safety and Health Association (OSHA). This Laboratory Annex also serves as an Annex to the Louisiana Pandemic Influenza Guidance, which describes the overall response for the Department of Health and Hospitals.

As there is little natural immunity to any new virus, it is recognized by LDH OPH that ongoing communications and updates to the health care community as well as the public are critical to the health of Louisiana. The recommendations that identify vulnerable populations and guidelines for treatment are also adopted by Louisiana, and the State remains in compliance with recommendations from such authorities as the Centers for Disease Control and Prevention (CDC).
