"rhinovirus (RV) (OR, 9.8), or both RV and RSV (OR , 10) was associated with increased asthma risk at age 6 years."
Birth-cohort data quantify a ~9.8-fold increase in odds of asthma at age 6 after early-life rhinovirus wheezing illness.

Hypotheses

Rhinovirus infection of the developing airway epithelium, in interaction with allergic (type 2) sensitization, injures and remodels the epithelium and biases the immune response toward the Th2 program, contributing to asthma inception rather than acting purely as a marker of pre-existing susceptibility.

"Among outpatient viral wheezing illnesses in infancy and early childhood, those caused by RV infections are the most significant predictors of the subsequent development of asthma at age 6 years in a high-risk birth cohort."
Identifies early rhinovirus wheezing illness as the most significant viral predictor of subsequent childhood asthma.
Pathophysiology:
Epithelial injury and Th2 skewing: Early-life rhinovirus infection of airway epithelium interacts with allergic sensitization to bias the developing airway toward type 2 inflammation.

notes: >-
  Directional trajectory: wheezing rhinovirus illnesses in infancy and early
  childhood are among the strongest predictors of childhood asthma. The
  within-disease mechanism (airway epithelial injury and Th2 skewing biasing
  toward asthma inception) is also captured as a pathophysiology node
  ("Early-Life Rhinovirus Wheezing Illness and Asthma Inception") in Asthma.yaml.
  This entry models the disease-to-disease directional signal. Whether early RV
  wheezing is causal in asthma inception or principally a marker of pre-existing
  susceptibility remains debated; the cohort evidence is consistent with a
  contributory causal role.
