Avian influenza is an infectious viral disease of birds caused by type A strains of the influenza virus.

Abstract

Avian influenza is an infectious viral disease of birds caused by type A strains of the influenza virus. Aquatic bird species have adapted to carry and transmit a wide range of influenza strains in nature. Here we report the results of a 4.5-year monitoring program for Orthomyxovirus prevalence in a population of wild mallard (Anas plathyrynchos) in northwestern Italy. To determine whether Orthomyxovirus prevalence affects survival, we used MARK software to compare the survival of AIV-positive versus AIV-negative birds. Prevalence rates and variance were estimated using inverse sampling method. The prevalence rate of influenza A virus was 4.3% (SE 0.00116) and lifespan was shorter (29.8%) for the young infected birds than for the young non-infected birds. © 2014 Taylor & Francis.
