JMM Profile: Avian influenza: a veterinary pathogen with zoonotic potential Open Access

This article is part of the JMM Profiles collection.

Abstract

Avian influenza viruses (AIVs) are classified as either low pathogenicity (LP; generally causing sub-clinical to mild infections) or high pathogenicity (HP; capable of causing significant mortality events in birds). To date, HPAIVs appear o be restricted to the haemagglutinin (HA) glycoprotein H5 and H7 AIV subtypes. Both LPAIV and HPAIV H5 and H7 AIV subtypes are classified as the causative agents of notifiable disease in poultry. A broad range of non-H5/non-H7 LPAIVs also exist that have been associated with more severe disease outcomes in avian species. As a result, the constant threat from AIVs causes significant economic damage in poultry production systems worldwide. The close proximity between mammalian and susceptible avian species in some environments provides the opportunity for both inter-host transmission and mammalian adaptation, potentially resulting in novel AIV strains capable of infecting humans.
