Infections are usually restricted to pigeon lofts. However, occasionally virulent strains of this virus can infect poultry, causing Newcastle Disease.

Avian Avulavirus AAvV-1 (PPMV-1) is a notifiable animal disease. If you suspect it, you must report it immediately by contacting the DAERA helpline on 0300 200 7840 (Mon-Fri 9 am to 5 pm) or your local DAERA Direct Regional Office.

If you report suspicion of Avian Avulavirus  AAvV-1, DAERA will investigate.
Anyone concerned about their birds should contact their PVP or their local DAERA Direct Regional Office.

Biosecurity and preventing welfare impacts in poultry and captive birds; how to spot Avian Avulavirus infection signs of Avian Avulavirus infection in pigeons may include:

nervous signs, including trembling wings and heads, and twisting of the neck, partial paralysis of wings and legs (birds may fall over on landing and be unable to feed), unusually wet and liquidy faeces (diarrhoea) that are often greenish in colourquietness, loss of appetite and reluctance to move sudden death.

The disease is very contagious, so it is common for most of the pigeons sharing a loft to display clinical signs at the same time.

How Avian Avulavirus is spread the disease is spread by direct contact between infected pigeons and non-infected pigeons and through:
pigeon transporters that have not been adequately cleaned and disinfected drinking water in lofts and transporters pigeon fanciers carrying infection on their clothes, hands and feet.

The disease can also be introduced to a loft of kept pigeons through contact with wild pigeons.
The disease can be spread to chickens if, for example, their feed is infected with the faeces of infected pigeons. In chickens, Avian Avulavirus can cause Newcastle Disease.

Preventing and controlling Avian Avulavirus infection in pigeons you can help prevent the disease by:
vaccinating your pigeons – talk to your vet for advice (if you run pigeons shows or races, you must ensure any bird taking part has been vaccinated). Practising strict biosecurity on your premises. Pigeons must be vaccinated every 12 months.  At the start of the racing year, owners must show proof that the correct vaccination has been administered within the last 12 months.  

If you organise a pigeon show or race, you must make sure only vaccinated pigeons participate.
If you own racing pigeons, you must keep a record of vaccinations and of every show or race each bird takes part in.

You should also refer to the following AI guidance. While AI and Avian Avulavirus AAvV-1(Pigeon Paramyxovirus) are separate diseases, both are Notifiable Epizootic Avian Diseases, and similar control/preventative measures apply to both diseases.

If the disease occurs in NI, the outbreak will be controlled in line with the Contingency Plan for Epizootic Diseases and the Notifiable Epizootic Avian Disease Control Strategy.
