Introduction to dog coronavirus diseases

Canine coronavirus (CCV) is an enveloped single-stranded RNA virus. The virus is mainly infected through the mouth, invading the villous epithelial cells, causing the villi to become thick and short, causing the dog's digestive enzymes and intestinal absorption function to lose, eventually leading to diarrhea. There have been no reports of viremia and infection of other internal organs in this disease. For dogs, dogs of different breeds, genders and ages can be infected, and puppies are most susceptible to infection because of their poor resistance. The incidence rate is almost 100% and the fatality rate is 50%. Sick dogs and virus-carrying dogs are the main sources of infection. The virus is transmitted to healthy dogs and other susceptible animals through direct and indirect contact through the respiratory and digestive tracts. This disease can occur throughout the year, but is more common in winter. Stress factors such as sudden changes in climate, poor sanitary conditions, high density of dogs, weaning and transfer, and long-distance transportation may all induce this disease.
