Novel avian influenza H7N3 strain outbreak, British Columbia

Emerg Infect Dis. 2004 Dec;10(12):2192-5. doi: 10.3201/eid1012.040743.

Abstract

Genome sequences of chicken (low pathogenic avian influenza [LPAI] and highly pathogenic avian influenza [HPAI]) and human isolates from a 2004 outbreak of H7N3 avian influenza in Canada showed a novel insertion in the HA0 cleavage site of the human and HPAI isolate. This insertion likely occurred by recombination between the hemagglutination and matrix genes in the LPAI virus.
