title: Severe Acute Respiratory Illness (SARI) Surveillance in Louisiana, 2013-2014.
abstract: The objectives of this article are to describe the severe acute respiratory illness (SARI) surveillance implemented in Louisiana during the 2013-2014 influenza season, present the epidemiology of reported SARI cases, and identify ways to improve this system by incorporating formal SARI surveillance into the influenza surveillance program. Of the 212 SARI cases, 181 (85%) had at least one underlying medical condition, 54 (25.7%) had two conditions, 43 (20.3%) had three conditions, and 25 (11.8%) reported four or more. The most common four underlying conditions were: obesity (43.4%), chronic cardiac conditions (39.6%), diabetes (29.7%), and chronic pulmonary conditions (26.9%). While obesity was the most reported underlying condition, it was three times more likely to be reported in less than 65 years old rather than those >65. Continuation of SARI data collection in future seasons will allow comparisons regarding severity, populations affected, and identify risk factors most commonly associated with severe illness. Reporting of SARI cases also increased influenza-associated adult mortality reporting to the Office of Public Health's Office of Infectious Diseases Epidemiology (ID Epi). Though all influenza-associated mortality is reportable in Louisiana, adult mortality was reported rarely prior to the 2013-2014 season.
