Bluetongue found in Swiss calf
Swiss veterinary authorities have reported a case of bluetongue in a calf in the western Canton of Fribourg. The animal, which was born last autumn, did not show any clinical symptoms and the infection was detected through routine monitoring. It is thought to have become infected last autumn, as the midges that transmit the bluetongue virus are not yet active. The case is the country’s only reported bluetongue infection of 2009. The Federal Veterinary Office said it showed that the vaccination campaigns of 2008 and 2009 had been successful in controlling the virus, but that it had not yet been completely eradicated.
