Low Pathogenicity Avian Influenzas and human health

Influenza A/H7N2 virus, as seen in the poultry outbreak described above, is one of many Low Pathogenicity Avian Influenzas (LPAIs) [1]. These have a genotype associated with causing milder symptoms in birds than the rarer high pathogenicity viruses and are negative on in vivo test [2,3].
