Baby's nose bugs may predict asthma risk
NCT ID NCT01978288
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study follows 180 infants from birth to age 2 to see how bacteria in their upper airways change over time. Researchers want to learn if certain bacteria lead to more airway inflammation and lower lung function, which could increase asthma risk. The study does not test any treatment, but aims to better understand how asthma develops.
