Bovine encephalitis virus, also known as BEV, is a viral infection that affects cattle and occasionally other livestock. Synonyms for this disease include bovine viral encephalitis, bovine spongiform encephalopathy, and viral brain inflammation in cows. BEV is transmitted through bites from infected mosquitoes and ticks, causing neurological symptoms such as fever, inability to stand, and staggering gait. In severe cases, it can lead to paralysis, coma, and death. Early diagnosis and preventive measures such as vaccination play a vital role in controlling the spread of BEV. Farmers and veterinarians must remain vigilant and take necessary precautions to safeguard livestock from this debilitating virus.
