Scotland has recorded its first confirmed case of bluetongue virus serotype 3 (BTV3), a potentially fatal disease affecting ruminants, after a lamb on a farm in Dumfries and Galloway tested positive last week. The animal was euthanised on welfare grounds, and the Scottish government has placed restrictions on the farm while further testing takes place. The case forms part of a wider UK outbreak that has continued to grow through the 2026/27 season, with the total number of confirmed infections rising in the days since Scotland's first case was announced.
What is bluetongue and how does it spread?
Bluetongue is a viral disease that typically affects cattle, sheep and goats, and is carried between animals primarily by biting midges. According to Scottish government guidance, the virus can also spread through infected animals themselves, as well as via semen, ova and embryos, meaning transmission is not limited to insect activity alone, according to Scottish government guidance. Infected cattle can display nasal discharge, swelling and redness around the lips, nose and muzzle, lameness or reluctance to stand, reduced milk yield and diarrhoea. The virus poses no risk to human health or food safety, but it can cause high mortality among infected sheep and fertility complications in cattle.
How did Scotland detect this case?
The infected animal, a lamb belonging to the Johnson family at Kirkmabreck Farm near Creetown in Dumfries and Galloway, was tested for BTV3 after showing symptoms consistent with the disease, according to the UK government. The case was recorded on Saturday, 8 August 2026, and the Scottish government confirmed the restrictions on the farm the following Tuesday, 11 August 2026. Because bluetongue is a notifiable disease, the case had to be reported to the Animal and Plant Health Agency in Scotland, which is now working alongside government officials to determine how the animal became infected.
The Johnson family, who said they had moved to Scotland from England four months earlier, confirmed the case in a social media post and said all their stock had been moved indoors to reduce the risk of further spread. They said the animals on the farm had been purchased locally, within 20 miles of their home, and had not been brought up from England, aside from their dogs and children.
"I literally can not believe that we have only been here four months and this is what we are faced with. This is not at all how we wanted to introduce ourselves to the locals but like the vet said, we haven't done anything wrong and it is all a case of rather bad luck."
According to official UK government figures, the case was formally confirmed on 8 August 2026, and epidemiological investigations are continuing to establish the likely source of the infection. Notably, separate Scottish government leaflet guidance has stated that there were previously no positive BTV3-infected animals identified in Scotland, underlining the significance of this newly confirmed case.
What are officials doing in response?
Scotland's chief veterinary officer, Sheila Voas, said it remains too early to determine whether the virus is now circulating more widely within the country or whether this represents an isolated incident.
"At this stage it is not possible to know if bluetongue is circulating in Scotland, or whether this is an individual case."
"The farm is under restriction while investigations, including testing other susceptible animals, are ongoing."
"Vaccination remains the best way of preventing disease in animals and I encourage all farmers to discuss this with their vets."
Ms Voas has also suggested a likely route of infection, saying it was probable the lamb picked up the virus from infected midges carried on the wind rather than through any direct contact with animals moved from elsewhere.
"We know there's disease in Northern Ireland, the Republic of Ireland, Isle of Man and the north of England so my working assumption is a plume of infected midges blew over and infected this animal and possibly others."
NFU Scotland has echoed calls for vaccination, particularly urging farmers in the south of the country to protect susceptible livestock. A spokesperson for the organisation said swift government action was essential to contain any potential spread.
"It is important that the Scottish government takes swift and effective steps to ascertain the scale and likely source of infection and, if necessary, puts appropriate controls in place to prevent spread outwith the local area through animal movements."
"This could include establishing appropriate disease control zones, movement controls and robust surveillance and testing."
How does this fit into the wider UK outbreak?
At the time the Scottish case was confirmed, official data showed 289 BTV3 cases recorded across the UK this season, with 283 in England, five in Wales and the single Scottish case. According to more recent government figures, the UK total had risen to 334 confirmed cases by 10 August 2026, comprising 326 in England, seven in Wales and one in Scotland, after 42 new English cases and two new Welsh cases were confirmed that day. Separately, the Agriculture and Horticulture Development Board has reported a total of 289 cases as of 10 August in some of its sector updates, a figure that differs from the government's most recent count.
A sharp rise in cases across south-west England has been attributed to unusually hot and humid weather, which the Animal and Plant Health Agency says has created favourable breeding conditions for the midges that transmit the virus.
The current outbreak echoes concerns raised earlier this year by farmers further south. In an earlier account from a Devon farmer, bluetongue was described as having left her feeling isolated as the disease spread through her flock, with 92 positive cases recorded in England by the end of July 2026.
What is the history of BTV3 in Great Britain?
Bluetongue serotype 3 was first detected in Great Britain on 10 November 2023, with the initial case disclosed on a farm near Canterbury in Kent, according to a government epidemiology report. Since then, the virus has continued to spread across parts of England, with the case in Dumfries and Galloway marking its first confirmed appearance north of the border. Scottish rules currently require animals moving from a restricted zone into Scotland to undergo PCR or ELISA testing, with samples taken within seven calendar days of the move, according to Scottish government movement guidance.
What happens next?
Investigations into the source of the Scottish infection, including testing of other susceptible animals on Kirkmabreck Farm, remain ongoing, with no public end date given, according to a regional broadcaster's report. Authorities have not indicated when results of the wider testing on the affected farm, or any conclusions about the source of infection, are expected to be released.
Key Facts
- Scotland's first confirmed BTV3 case involved a lamb at Kirkmabreck Farm near Creetown, Dumfries and Galloway, owned by the Johnson family, confirmed on 8 August 2026.

- UK case numbers have grown quickly: 289 cases were reported when the Scottish case was confirmed, rising to 334 by 10 August 2026 (326 in England, seven in Wales, one in Scotland), according to government figures.
- Scotland's chief veterinary officer believes the lamb likely contracted the virus from midges blown over from areas including Northern Ireland, the Republic of Ireland, the Isle of Man and the north of England.
- BTV3 was first detected in Great Britain near Canterbury, Kent, on 10 November 2023.
- The virus poses no risk to human health or food safety but can be fatal in sheep and cause fertility issues in cattle.
