Recently, the emergence and rapid global dissemination of novel swine-origin influenza A virus (H1N1) with unique epidemiologic characteristics has heightened awareness and concern of this viral pathogen, and its potential for major disruption of both civil and military stability. Although advances in medical and scientific technologies have improved our basic understanding of respiratory disease, many questions about the epidemiology and immunology of ARI remain unanswered. This study plans to initiate a multi-site, multi-disciplinary research collaboration, termed the Acute Respiratory Infection Consortium (ARIC) for the purpose of studying the etiology, epidemiology and immunology of influenza-like illness (ILI) in order to describe the natural history and risk factors for disease, as well as the characteristics of the host immune response.

At the core of the ARIC is the proposed observational, longitudinal study of the Natural History Study of ILI among active duty military members, healthy retirees, and their dependents recruited from both inpatient and outpatient settings of military treatment facilities (MTF) in the continental US to be followed for a total of four (4) visits over a 28-day period. Additionally, the investigators also propose to conduct a household-based study of influenza (Family Transmission Study) in which individuals who have a laboratory-confirmed influenza illness will be recruited and enrolled along with their family members for the purpose of studying transmission of influenza within households. Taken together, these studies will establish a longitudinal cohort of ILI among active duty members and their families, as well as a repository of biological specimens relevant to the epidemiology and immunology of infection. Ultimately, these studies will serve as a solid foundation on which future investigations of ARI epidemiology, treatment and prevention can be based.

Primary Outcome Measures:
  • Develop a consortium of DoD research sites capable of collecting detailed prospective clinical data, and biologic samples from active duty members and their families with ILI. [ Time Frame: 7 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Develop and validate an influenza severity scale [ Time Frame: 6 months ] [ Designated as safety issue: No ]
  • Study the relationship between health and fitness of young adults to outcomes of influenza and other respiratory viruses [ Time Frame: 1 year ] [ Designated as safety issue: No ]
  • Examine the relationship of cell-mediated and humoral immune response to the severity of influenza and other respiratory viruses. [ Time Frame: 1 year ] [ Designated as safety issue: No ]
  • Describe patterns of viral shedding in different influenza types and subtypes. [ Time Frame: 1 year ] [ Designated as safety issue: No ]
  • Correlate clinical severity and cytokine/humoral response with underlying host genotype. [ Time Frame: 1 year ] [ Designated as safety issue: No ]

Natural History Study
The core Natural History Study of ILI is an observational, longitudinal cohort study using data from clinical findings, medical chart review, and diagnostic, virologic and immunologic laboratories to describe the epidemiology and immunology of ILI. This study aims to describe the clinical history of influenza and other predominant viral respiratory pathogens in an otherwise healthy population of US military active duty members and their dependents. The primary focus will be the etiology, natural history and immunology of ILI in otherwise healthy adults and children. We will recruit subjects with ILI in both the outpatient and inpatient setting, and will serially collect biological specimens (e.g. nasal/OP swabs, blood, rectal swabs) over a 28-day period. In addition, we will collect a single buccal (cheek) swab.
HIV Positive Cohort
An additional objective of the study will be to descriptively examine the clinical and laboratory characteristics of ILI events among HIV-infected persons using the military's substantial experience in following a stable HIV-infected population. Information on prior medical conditions and/or hospitalizations and immunization history will be collected via medical chart review. Information on risk factors for ILI will be ascertained through interview-administered questionnaires.


Ages Eligible for Study:   up to 65 Years   (Child, Adult)
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes
Sampling Method:   Probability Sample
Study Population
Males and females of all ages and of military (including active duty enlisted and active duty officers from all branches of service), healthy retirees, and their dependents (spouses and children) presenting to inpatient/outpatient facilities with ILI will be eligible for participation. At select sites, military members and their family members (healthy spouses and children) may be eligible for participation in the study of household transmission of influenza. All children, regardless of study site, will be excluded from the direct collection of blood specimens for research purposes alone. Only discard blood will be collected from children and no additional needle sticks will occur in children. Blood will only be collected from children if indicated by the primary care physician.
