Unfortunately we have had our first case of Bluetongue (BTV-3) confirmed within the practice in an unvaccinated cow near Okehampton. We are still well within the midge vector transmission season and the risk of new infections remains very high.
Whilst the reported number of cases in the UK is only 117 this vector season, with most of these cases only occurring since early September, it is important to note that the true number will be much higher. This is because APHA will only test up to 3 animals on a holding that has a suspicion of BTV-3, so many more are likely to be infected. In addition, the clinical signs in cattle are very subtle and often missed. Unfortunately, the true impact of BTV-3 may unfortunately not be realised until calving and lambing time, with the birth of non-viable youngstock. The two pictures show the SW case map on 8th September and then today.
Vaccination remains the only effective way to prevent BTV-3 infection.
