An Insight into Avian influenza
Avian influenza, also known as ‘Bird flu’, is a notifiable disease and must be reported immediately. It is caused by Orthomyxovirus Type A. There are high and low pathogenic strains that affect a wide range of avian hosts, and a natural reservoir lies in populations of wildfowl such as migratory ducks and geese. Currently, the risk of exposure in the UK is low, but increased outbreaks are common in the autumn due to the migratory pattern of waterfowl and environmental conditions becoming more favorable for virus survival. The virus has been found across East Anglia, Kent and the Midlands in the UK. North and Eastern Europe have a high incidence of highly pathogenic avian influenza (HPAI) outbreaks. The risk is greater when birds are in close proximity to migratory bird refuge areas such as tidal marshes and standing water.
