“What we’re advising is three-fold,” Dr. Joseph Henry, president of the Sheep Veterinary Society and member of RH&W’s steering group mentioned.
“Farmers have to beware when shopping for animals in, particularly from Europe, take motion to report any indicators of the illness, and always, stay vigilant.”
BTV-3 is a viral illness transmitted by biting midges, which impacts all ruminants (e.g. sheep, cattle, goats and deer) and camelids (e.g. llama and alpaca).

“BTV-3 seems to imitate BTV-8 in its behaviour, main us to be extraordinarily cautious to the chance it poses.
“At the moment, there aren’t any reviews of the brand new pressure within the UK. However it’s felt that as a result of nature of bluetongue’s skill to unfold by way of contaminated midges, and present heat climate situations, the chance of it reaching the UK is rising, so we should adhere to recommendation and do all we are able to to maintain it out.”
