*HRV, human rhinovirus; case-patients, asthma patients with exacerbations; controls, asthma patients without exacerbation.
†HRV genotype based on partial virus capsid protein (VP1) gene sequence. Serotype designation based on >90% VP1 amino acid sequence identity with respective prototype strains.
‡Strain GA23584 showed 73.0% amino acid sequence identity with HRV80.
§Genogroup C HRVs form a clade phylogenetically distict from species A and B HRVs.
