Blue Tongue Virus (BTV) is a significant concern for livestock health, especially in ruminants.

• Among its various strains, Blue Tongue Virus Type 3 (BTV-3) has become increasingly prevalent, causing serious economic and animal welfare issues.
• Understanding the disease and the importance of vaccination is crucial for herd protection.
  BTV is transmitted primarily through biting midges (Culicoides spp.), which are most active during warmer months.

• Once infected, animals can exhibit a range of symptoms, including swelling of the face and tongue, excessive salivation, lameness, abortion, and, in some cases, death.
• Sheep are particularly susceptible, often displaying more severe clinical signs than cattle, although cattle can act as reservoirs of the virus.
