The purpose of this study is to investigate whether influenza can be reliably transmitted from children to susceptible contacts in a health care setting. The goal is to develop a transmission that can then be used to assess interventions to prevent transmission

Research objectives:

To develop a model to investigate the frequency of influenza transmission from an infected child to a susceptible health care worker

Research Hypotheses:

Influenza viruses can be transmitted from infected children to exposed health care workers


Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Pilot Study to Develop a Model to Evaluate Nosocomial Transmission of Influenza

Primary Outcome Measures:
  • Frequency of transmission of influenza [ Time Frame: 1 weeks ]

Biospecimen Retention:   Samples Without DNA
Throat and nose swabs

Estimated Enrollment: 50
Study Start Date: December 2008
Estimated Study Completion Date: May 2009
Estimated Primary Completion Date: April 2009 (Final data collection date for primary outcome measure)
Heathcare worker
health care worker exposed to patient with influenza

Detailed Description:

CHildren with influenza infection presenting to ED will be identified by RAT. Healthy healthcare worker subjects will expose themselves and perform specific activities with the child.

subjects will be followed by diary card, clinical symptom scores and virology swabs to assess frequency of transmission
