Brief Summary:
In this study, the investigator will be approaching pregnant women to undertake 2 years of weekly respiratory and nappy specimen collection from their healthy new born infant. These specimens will be mailed to the Queensland Paediatric Infectious Diseases (Qpid) Laboratory where they will be stored and batched tested for viruses and bacteria. As well as this, parents will keep a simple daily symptom diary for their child, allowing us to match detection of viruses and bacteria to periods when the study child did or did not have symptoms. This will help our understanding of what finding these viruses and bacteria in specimens from children really means.

Primary Outcome Measures :
  1. Acute respiratory illness (ARIs) and acute gastrointestinal (AGE) illness rates per 10,000 child-days in healthy children in the first two years of life [ Time Frame: Two years ]
    This measure will be calculated using counts of ARIs and AGE in study children during the first two years of life as the numerator, and person-time in child-months on the study as the denominator.


Secondary Outcome Measures :
  1. Pathogen-specific rate of episodes of ARI and AGE per 10,000 child-days in healthy children in the first two years of life [ Time Frame: 2 years ]
    Viral and bacterial testing will allow to calculate pathogen-specific rates: This measure will be calculated using counts of pathogen-specific ARIs and AGE in study children during the first two years of life as the numerator, and person-time in child-months on the study as the denominator.

  2. Detection of novel pathogens in healthy children in the first 2 years of life. [ Time Frame: 2 years ]
    A subset of samples collected during this study will be used to attempt to identify previously undetected pathogens in children, through microarray technology and random primer PCR testing.
