Canine Parvovirus (Parvo)

A highly contagious and severe viral disease in dogs that attacks the gastrointestinal tract and white blood cells.

Detailed explanation

Canine Parvovirus, commonly known as Parvo, is a highly contagious and potentially fatal viral illness that primarily affects puppies and unvaccinated dogs. The virus targets the rapidly dividing cells in the intestinal lining and bone marrow, leading to severe gastrointestinal upset and a weakened immune system. Transmission occurs through contact with infected feces, contaminated environments, or infected dogs. Symptoms can appear rapidly and worsen quickly, making early veterinary intervention crucial. While there is no cure for the virus itself, aggressive supportive care, including intravenous fluids, anti-nausea medications, and antibiotics for secondary infections, can improve outcomes. Vaccination is the most effective way to prevent Parvo.
