Dear Ockert,

Below is some information that we researched last year when a reporter who was reporting on the AI and NCD outbreaks asked questions about the NCD outbreak. I have also attached the references that my colleagues and I were using.

Controlled diseases are managed according to the regulations prescribed by the Animal Diseases Act (Act 35 of 1984).

Animal disease Nature, causal organism and symptoms Susceptible animals Controlled veterinary act to be performed in respect of-
Susceptible animals Contact animals Infected animals
1 2 3 4 5 6
  Newcastle disease Highly contagious viral disease caused by avian paramyxovirus 1 (velogenic or mesogenic) strains that cause or have the potential to cause severe disease characterised by respiratory distress, greenish diarrhoea, occasionally nervous symptoms and high mortality. Poultry and birds All fowls, domesticated ostriches and racing pigeons in the Republic shall be immunised and kept immunised by the responsible person with an efficient remedy according to the manufacturer's instructions for use thereof Contact animals shall be isolated and immunised by the responsible person with an efficient remedy Infected animals shall be isolated and be destroyed or dealt with as determined by the director.
             

Properties where infected birds have been detected are put under quarantine and dealt with as prescribed.

Wild birds can carry the virus without becoming ill and can therefore transmit it to other birds they come into contact with or through their secretions. Birds in the pigeon family can shed the virus intermittently for a year or more.

As you can see, racing pigeons are included in the wording of the regulations but I see your point that not having a registered vaccine would be problematic.

There have definitely been at least 2 cases (laughing dove and crow) where the Provincial vet lab detected virulent NCD virus but the PPMV PCR at OVI was negative. You can contact Dr Lesley van Helden (This email address is being protected from spambots. You need JavaScript enabled to view it.) or Dr Laura Roberts (This email address is being protected from spambots. You need JavaScript enabled to view it.) our 2 epidemiologists if you would like them to run a query on the database to find exact numbers. I also know that at some point Dr van Helden spoke to the labs about what the different tests detect, so if the questions you are fielding are at the point where you need this information, she is a good person to speak to. Her number is 0218085017.

Kind regards,

Aileen
