    . In the case of avian influenza virus, [migratory] birds have been suggested to play a role in the spread of some highly pathogenic strains (e.g. H5N1, H5N8), as well as their low pathogenic precursorsprecursorsSubject Category: Miscellaneous

    of LPAIVs on bird movement need to be evaluated. In a key host species, the mallard Anas platyrhynchosanas platyrhynchosSubject Category: Organism Names

    , we tested whether LPAIV infection status affected daily local (<100 m) and regional (>100 m) movements by comparing movement behaviour (1) within individuals (captured and sampled at two time points) and (2) between individuals (captured and sampled at one time point). We fitted free-living adult males with GPS loggers throughout the autumn LPAIV infection peak, and sampled them for LPAIV infection at logger deployment and at logger removal on recapture. Within individuals, we found no association between LPAIV infection and daily local and regional movements. Among individuals, daily regional movements of LPAIV infected mallards in the last days of tracking were lower than those of non-infected birds. Moreover, these regional movements of LPAIV infected birds were additionally reduced by poor weatherweatherSubject Category: Climate Related

    decreased. Our study thus demonstrates that bird-assisted dispersal rate of LPAIV may be lower on a regional scale than expected on the basis of the movement behaviour of non-infected birds. Our study underlines the importance of understanding the impact of pathogen infection on host movement in order to assess its potential role in the emergence and spread of infectious diseasesinfectious diseasesSubject Category: Diseases, Disorders, and Symptoms
