Canine distemper is a highly contagious viral disease that affects dogs and, to a lesser extent, cats and other animals like ferrets and raccoons. It is caused by the canine distemper virus (CDV), which spreads through respiratory secretions and contact with contaminated surfaces. Distemper can lead to a wide range of symptoms, including respiratory issues, fever, vomiting, diarrhea, neurological signs such as seizures, and even death in severe cases. Vaccination is crucial in preventing distemper, as there is no specific cure once an animal is infected. Veterinary treatment focuses on supportive care to manage symptoms and boost the immune system's ability to fight off the virus. Due to its contagious nature and potentially devastating consequences, preventing distemper through vaccination and responsible pet management practices is essential for protecting the health and well-being of dogs, cats, and other susceptible animals.
