Hypothesis

Do viral infections in early life contribute to the development of asthma?

Conclusion

Early life viral infections, particularly from rhinovirus, are linked to a higher risk of developing asthma in children.

Supporting Evidence

  • Viruses are found in 80-85% of children experiencing asthma exacerbations.
  • Rhinovirus is the most common virus detected during asthma exacerbations.
  • Children born around 4 months before the peak of the viral season have a significantly increased risk of asthma.

Takeaway

Getting sick with certain viruses when you're a baby can make it more likely that you'll have asthma when you grow up.

Methodology

The study followed over 95,000 children to analyze the relationship between the timing of viral infections and asthma development.

Potential Biases

Potential biases due to the observational nature of the study and lack of control groups for certain analyses.

Limitations

The study did not determine the specific viruses responsible for the peak of the viral season.

Participant Demographics

Children enrolled in the Tennessee Medicaid program, born between 1995 and 2000.
