The UK’s Chief Veterinary Officer has urged farmers to stay vigilant for bluetongue virus. There was a latest improve in confirmed BTV-3 circumstances within the Netherlands, Germany and Belgium with some animals exhibiting extreme scientific indicators.
Farmers are reminded that free testing is now out there for animals shifting from the best danger counties to dwell elsewhere in Nice Britain or to be offered at a market inside a high-risk county the place there shall be patrons from outdoors the high-risk counties. This can assist guard in opposition to animal actions probably transporting undetected illness to new areas. The high-risk counties are Norfolk, Suffolk, Essex, Kent and East Sussex.
Final November, APHA and The Pirbright Institute recognized the primary case of the illness in Nice Britain by means of the annual bluetongue surveillance programme.
Bluetongue virus is primarily transmitted by midge bites and impacts cattle, goats, sheep and camelids comparable to llamas. The impacts on vulnerable animals can differ drastically – some present no scientific indicators or results in any respect whereas for others it may well trigger productiveness points comparable to diminished milk yield, whereas in probably the most extreme circumstances will be deadly for contaminated animals. Bluetongue doesn’t have an effect on human well being or meals security.
The virus will also be unfold by means of germplasm (semen, ova, and embryos) in addition to transmitted from mom to unborn offspring.
Present state of affairs
There are at the moment no dwell circumstances of bluetongue virus and no proof that there’s circulating bluetongue virus in England. Nevertheless, given the rise in temperature, there’s now an elevated danger and bluetongue transmission is feasible.
Biting midge exercise will increase with the hotter climate, and there stays a very excessive chance of a brand new introduction of bluetongue virus serotype 3 (BTV-3) into livestock in Nice Britain in 2024 by means of contaminated biting midges being blown over from northern Europe, the place plenty of circumstances have now been detected.
Farms near the coast in counties alongside the east coast of England from Norfolk to Kent and alongside the south coast from Kent to Devon are at highest danger of incursion.
Biting midges are most energetic between April and November and the timing of a possible incursion will depend upon the temperature and wind patterns. There may be an energetic surveillance programme working, which includes the trapping of midges throughout the nation and dealing with companions such because the Met Workplace to observe the possible unfold of the virus based mostly on temperature and wind patterns.
Farmers ought to proceed to observe their animals continuously for scientific indicators and ensure their animals and land are registered with APHA so we will find animals within the occasion of an outbreak.
Surveillance of vulnerable animals and epidemiological assessments will proceed. We’ll maintain the state of affairs beneath assessment.

Management of the illness
The Bluetongue Serotype 3 Illness Management Framework was developed in dialogue with the farming trade. It units out how illness management efforts will deal with motion management of vulnerable animals and their germinal merchandise (semen, eggs, ova and embryos) as a precautionary software to stem unfold of the illness till a secure and efficient vaccine for bluetongue virus serotype 3 (BTV-3) turns into broadly out there.
Work is underway with vaccine producers to facilitate secure entry to a BTV-3 vaccine as quickly as potential, however it is important that any vaccine has the boldness of trade, customers and buying and selling companions. This consists of understanding the efficacy of any vaccine deployed throughout all species, along with potential impacts on commerce.
UK Chief Veterinary Officer Christine Middlemiss stated:
“Bluetongue doesn’t pose a menace to human well being or meals security, however the illness can affect livestock farms, and trigger productiveness points.
“Though there are at the moment no dwell circumstances of bluetongue virus in Nice Britain, we all know that the probability of the virus getting into is growing and so I might urge farmers to stay vigilant and report any suspicions to the Animal and Plant Well being Company.
“If you happen to intend to maneuver animals to dwell out of high-risk counties please benefit from this free testing as it should assist cease the motion of undetected illness.”
Animal and Plant Well being Company interim Chief Government Jenny Stewart stated:
“The latest improve in circumstances in Europe underlines how vital it’s for farmers and animal keepers to proceed monitoring their livestock and to take up the supply of free testing the place crucial.
“The Animal and Plant Well being Company’s danger evaluation confirmed there’s a very excessive likelihood of bluetongue virus getting into Nice Britain this yr, and our world-leading scientists, vets and area groups stand able to sort out an outbreak of bluetongue virus and guarantee farmers are saved updated and supported.”
Strict guidelines on the motion of livestock from areas affected by bluetongue are already in place and farmers are reminded that animals imported from these areas should be accompanied by the related paperwork to obviously present they meet sure situations designed to scale back illness danger, comparable to appropriate vaccination.
Following affirmation of BTV in a non-imported animal in England, some buying and selling companions might prohibit exports of bluetongue vulnerable animals or their merchandise. The most recent data on availability of particular person export well being certificates will be discovered on Gov.uk.
NI and GB ruminants can’t be exported from an GB Meeting Centre to the European Union or moved to Northern Eire till additional discover.
BTV is a notifiable illness. Suspicion of BTV in animals in England should be reported to the Animal and Plant Well being Company on 03000 200 301
