Human infection with highly pathogenic A(H7N7) avian influenza virus, Italy, 2013

Simona Puzelli et al. Emerg Infect Dis. 2014 Oct.

Abstract

During an influenza A(H7N7) virus outbreak among poultry in Italy during August-September 2013, infection with a highly pathogenic A(H7N7) avian influenza virus was diagnosed for 3 poultry workers with conjunctivitis. Genetic analyses revealed that the viruses from the humans were closely related to those from chickens on affected farms.

Phylogenetic analysis of the hemagglutinin gene of the influenza A(H7N7) virus, Italy, isolated from humans during August–September 2013. The phylogenetic tree was constructed by using the neighbor-joining method and MEGA 5 software (http://www.megasoftware.net) with 1,000 bootstrap replicates (bootstrap values >70% are shown next to nodes). The influenza A(H7N7) virus isolated from a human in 2013 is shown in boldface. Scale bar indicate nucleotide substitutions per site.
