DoD Global, Laboratory-based, Influenza Surveillance Program

Our mission is to provide an operationally relevant, global, laboratory-based influenza surveillance program that encompasses the most important respiratory diseases affecting the U.S. military.

If you are a sentinel site, we have compiled key resources (links below) to help prepare for the upcoming influenza surveillance season. The data gathered from your site will be used to track influenza activity, monitor the trends in new and existing influenza virus strains, and will be used to help shape next season's influenza vaccination.

If you have questions, please contact us at via email or call 1-937-938-3196.

According to the Centers for Disease Control and Prevention, the flu is a contagious respiratory illness caused by influenza viruses, and the best prevention is getting a flu vaccine each year.

Outbreak of Influenza and Rhinovirus co-circulation among unvaccinated recruits, U.S. Coast Guard Training Center Cape May, NJ, 24 July – 21 August 2016

Infographic
2/5/2018
On 29 July 2016, the U.S. Coast Guard Training Center Cape May (TCCM), NJ, identified an increase in febrile respiratory illness (FRI) among recruits who were unvaccinated against seasonal influenza as a result of the annual vaccine’s expiration. This report characterizes the outbreak and containment measures implemented at TCCM during the outbreak period. In 2016, respiratory infections affected more than 250,000 U.S. service members and comprised approximately 22% of medical encounters among military recruit populations – who are highly susceptible to respiratory infections. Seasonal influenza and rhinovirus are two of the leading respiratory pathogens. During the Surveillance Period: 115 recruits reported respiratory infection symptoms. Pie chart 1 shows the following data: •	41 (35.7%) suspected cases •	74 (64.3%) confirmed cases Among confirmed cases, lab specimens tested positive for: •	Influenza A 34 (45.9%) •	Rhinovirus 28 (37.8%) •	Influenza A and rhinovirus co-infection 11 (14.9%) •	Rhinovirus and adenovirus co-infection 1 (1.4%) Data above depicted in pie chart 2. •	24 July – 6 August, Influenza predominated •	7 August – 20 August, Rhinovirus predominated Although the outbreak significantly affected operations at TCCM, a timely and comprehensive response resulted in containment of the outbreak within 5 weeks. Key Factor for Outbreak Control •	Rapid detection through FRI sentinel surveillance •	Quick decision-making •	Streamlined response by using a single chain of command •	Rapid implementation of both nonpharmaceutical and pharmaceutical interventions Access the full report in the January 2018 MSMR (Vol. 25, No. 1).

This report characterizes the outbreak and containment measures implemented at the U.S. Coast Guard Training Center Cape May (TCCM), New Jersey, during a July 24 – August 21, 2016 outbreak period.

Department of Defense Global, Laboratory-based Influenza Surveillance Program’s Influenza vaccine effectiveness estimates and surveillance trends, 2016 – 2017 Influenza Season

Infographic
2/5/2018
Each year, the Department of Defense (DoD) Global, Laboratory-based Influenza Surveillance Program performs surveillance for influenza among service members of the DoD and their dependent family members. In addition to routine surveillance, vaccine effectiveness (VE) studies are performed and results are shared with the Food and Drug Administration, Centers for Disease Control and Prevention, and the World Health Organization for vaccine evaluation. This report documents the annual surveillance trends for the 2016 – 2017 influenza season and the end-of-season VE results. The analysis was performed by the U.S. Air Force School of Aerospace Medicine Epidemiology Laboratory, and the DoD Influenza Surveillance Program staff at Wright-Patterson Air Force Base, OH. FINDINGS: A total of 5,555 specimens were tested from 84 locations: •	2,486 (44.7%) negative •	1,382 (24.9%) influenza A •	1,093 (19.7%) other respiratory pathogens •	443 (8.0%) influenza B •	151 (2.7%) co-infections The predominant influenza strain was A (H3N2), representing 73.8% of all circulating influenza. Pie chart displays this information. Graph showing the numbers and percentages of respiratory specimens positive for influenza viruses, and numbers of influenza viruses identified, by type, by surveillance week, Department of Defense healthcare beneficiaries, 2016 – 2017 influenza season displays. The vaccine effectiveness (VE) for this season was slightly lower than for the 2015 – 2016 season, which had a 63% (95% confidence interval: 53% - 71%) adjusted VE. The adjusted VE for the 2016 – 2017 season was 48% protective against all types of influenza.  Access the full report in the January 2018 MSMR (Vol. 25, No. 1). Go to: www.Health.mil/MSMR

This infographic documents the annual surveillance trends for the 2016 – 2017 influenza season and the end-of-season vaccine effectiveness.
