New Forest commoners are being warned to be vigilant about the rise in Bluetongue Virus (BTV), as the control zone for the disease has entered Hampshire.
BTV is a non-contagious, viral disease affecting domestic and wild ruminants (sheep, cattle, goats, and deer), which is transmitted by biting midges. It does not affect people or food safety, but outbreaks can result in prolonged animal movement and trade restrictions.
Clinical signs include:
- Lameness
- Lethargy
- Ulcers/sores around nose and mouth
- Fever
- Not eating
- Milk drop
Outbreaks occur when susceptible sheep, particularly European breeds, are introduced to endemic areas or when the virus is introduced to a region by windborne movement of infected Culicoides (midges species). It can also be introduced through the import of an infected animal or germinal products (semen or embryos).
Infected cattle/sheep/deer/goats play a significant role in maintaining the virus in a region. Livestock may serve as a source of the virus for several weeks while displaying little or no clinical signs of disease and are often the preferred host for insect vectors.
If you spot any signs listed above, inform the APHA (Animal and Plant Health Agency) immediately on 03000 200 301.
