Primary Outcome Measures:

Measuring the incidence of RSV-associated, LRI or apnea among infants <1 yr. old presenting the Emergency Dept. during shoulder months. [ Time Frame: July 2008 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Clinical outcome of infants at Emergency Dept. with RSV-associated LRI or apnea.(hospital admission, 23 hr.-observations,no. of outpatient and/or urgent care visits,ICU,mechanical ventilation,supplemental oxygen use, meds,admission rate) [ Time Frame: July 2008 ] [ Designated as safety issue: No ]
Societal burden(no. of days lost from work by parent/guardian) for infants through 14 days after index ED visit and through hospital discharge. [ Time Frame: July 2008 ] [ Designated as safety issue: No ]
Comparison of rates of RSV-associated LRI or apnea during the peak periods and between shoulder and peak periods. [ Time Frame: July 2008 ] [ Designated as safety issue: No ]
Overall rates of RSV-associated LRI or apnea based on general ED statistics collected during the entire study period, including outside recruitment periods. [ Time Frame: July 2008 ] [ Designated as safety issue: No ]

Biospecimen Retention: Samples Without DNA

Groups/Cohorts	Assigned Interventions
1 Bronchiolitis, pneumonia or Lower Respiratory Infection or LRI (Season 1: 2006-'07 and same for Season 2: 2007 - '08)	Other: Emergency Dept. Subjects with LRI or Apnea No intervention; Epidemiological Study
2 Bronchiolitis, pneumonia or Lower Respiratory Infection or LRI (Season 1: 2006-'07 and same for Season 2: 2007 - '08)	Other: Emergency Dept. Subjects with LRI or Apnea No intervention; Epidemiological Study
3 Bronchiolitis, pneumonia or Lower Respiratory Infection or LRI (Season 1: 2006-'07 and same for Season 2: 2007 - '08)	Other: Emergency Dept. Subjects with LRI or Apnea No intervention; Epidemiological Study

Detailed Description:

The primary objective of this study is to describe the incidence of RSV-associated LRI or apnea (% RSV positive) among infants <1 year of age presenting to the ED during selected shoulder months. The total number of events will also be described.
To characterize the clinical outcomes and demographic data of infants presenting to the ED with RSV-associated LRI or apnea
To characterize the social burden (in the form of number of days lost from work by parent/ guardian) for these infants through 14 days after the index ED visit and through hospital discharge will also be described.
Based on a sample of cases collected in a cohort of patients enrolled at or near the peak of RSV disease during the traditional season, a comparison of the rate of RSV between shoulder and peak periods will be described.
To describe the overall rates of RSV-associated LRI or apnea based on the general ED statistics collected during the entire study period.

Criteria

Inclusion Criteria:

Written informed consent from parent/guardian to participate in this study
Male and female infants <1 year of age (child must be entered before his/her 1st birthday)
Physician diagnosis of either a) acute LRI or b) apnea below:

A) Acute LRI, defined as:

Medical diagnosis of bronchiolitis or pneumonia, or
In the absence of either of these diagnoses, LRI will be determined by the investigator after review of the medical record and must include at least one of the following:
- Retractions
- Wheezing
- Rales or crackles
- The presence of a new infiltrate, if a chest X-ray is available, which must be diagnosed by the ED physician or radiologist

B) Apnea, defined as either:

Cessation of breathing for >20 seconds by history or observation, or
Cessation of breathing for any length of time if accompanied by cyanosis or pallor, bradycardia as detected by a monitor, or
ED primary diagnosis of apnea
- Parent/guardian has the ability and willingness to be available for a follow-up interview by telephone

Exclusion Criteria:

Use of palivizumab or RSV-IGIV at any time prior to enrollment
Participation in trials of investigational RSV prophylaxis or therapeutic agents
