Session: Poster Abstract Session: HAI: Outbreaks

Room: Poster Hall
Background: Influenza occurs in distinct outbreaks of varying extent every year. In the United States, flu season occurs in the fall and winter. The peak of flu season has occurred anywhere from late November through March. We report the occurrence of an influenza A outbreak in our hospital in July 2015.
Methods: A patient admitted for management of a foot infection was discovered to have an influenza-like illness (ILI). He reported his roommate had an ILI; he was tested for influenza using the Cepheid Xpert Flu system (Cepheid, Sunnyvale, CA) and was found to have Influenza A. He was further tested using the Genmark eSensor XT8system and determined to have influenza A H3. Informal discussion with some staff regarding this unusual occurrence was done. An outbreak of influenza was determined on 7/6/2015 after 3 patients were found to be positive with influenza A within 24 hours. Contacts of patients with influenza were offered oseltamivir and influenza vaccination if they had not received it prior that year.
Results: Twenty positive influenza A H3 infected patients were discovered from 7/1-16/2015. The outbreak peaked on 7/7-9/2015 with 11 cases occurring that day. No further cases were discovered after 7/15/2015. Over 36 exposed employees were seen by Occupational Health and offered prophylaxis treatment. Over 14 direct patient care staff reported with ILI symptoms were granted leave. The Environmental Management Service provided additional infection control cleaning services in the involved areas. Hospital-wide communication to staff regarding standard infection control and prevention techniques was done.
Conclusion: Low-level influenza infection can be around year-long in the community. Rapid consideration of any patient or staff with ILI for influenza testing and treatment with prophylaxis is warranted especially in close environment, especially health-care settings.
