Highly pathogenic avian influenza A(H7N3) virus in poultry workers, Mexico, 2012

Emerg Infect Dis. 2013;19(9):1531-4. doi: 10.3201/eid1909.130087.

Abstract

We identified 2 poultry workers with conjunctivitis caused by highly pathogenic avian influenza A(H7N3) viruses in Jalisco, Mexico. Genomic and antigenic analyses of 1 isolate indicated relatedness to poultry and wild bird subtype H7N3 viruses from North America. This isolate had a multibasic cleavage site that might have been derived from recombination with host rRNA.

Keywords: H7N3; Mexico; conjunctivitis; highly pathogenic avian influenza A virus; influenza virus; poultry workers; viruses.
