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.

Odds ratio for asthma at age 6 given rhinovirus wheezing in the first

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

evidence_source: HUMAN_CLINICAL
snippet: "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."
explanation: >-
Identifies early rhinovirus wheezing illness as the most significant viral
predictor of subsequent childhood asthma.
pathophysiology:
- name: Epithelial injury and Th2 skewing
description: >-
Early-life rhinovirus infection of airway epithelium interacts with
allergic sensitization to bias the developing airway toward type 2
inflammation.
