Since 2009, VA Office of Public Health has monitored influenza and influenza-like-illness (ILI) activity using the VA's Healthcare Associated Infection and Influenza Surveillance System (HAIISS). Analysis of data from the 2012-2013 Influenza Season showed increases in outpatient visits, hospitalizations, telephone triage calls, total testing and positive influenza tests, indicating that the 2012-2013 season required more healthcare resource utilization.  Additionally, more Veterans ≥ 65 years of age sought care compared to the last 2 seasons. Strain characterization demonstrated HA epitope differences compared to vaccine strains. Vaccine procedure data showed that influenza immunization among VA patients could be improved upon.
