Abstract

To determine links between human rhinoviruses (HRV) and asthma, we used data from a case-control study, March 2003-February 2004, among children with asthma. Molecular characterization identified several likely new HRVs and showed that association with asthma exacerbations was largely driven by HRV-A and a phylogenetically distinct clade of 8 strains, genogroup C.

Phylogenetic tree of partial virus capsid protein 1 (VP1) amino acid sequences of human rhinoviruses (HRVs) identified in 29 HRV-positive pediatric asthma patients, March 2003–February 2004, Atlanta, Georgia, USA (designated *), previously published sequences of strains QPM (GenBank accession no. EF186077), C024-C026 (accession nos. EF582385–EF582387), and NAT001 and NAT045 (accession nos. EF077279–EF077280). HRV prototype strains designated 1A, 1B, 2-100. Human enterovirus (HEV) 68/HRV87 (designated 68/87) is included as outgroup. Tree construction and bootstrap values determined with PAUP* (11).
