What are the sequelae of canine distemper?

Canine distemper, also known as canine fever, is a disease that occurs in canines. The main reason is that all animals in the family are infected. This disease has a great impact on animals, and even has a very high mortality rate. It can be transmitted between animals. In addition to being transmitted through food, it can also be transmitted through the air. Fortunately, this disease will not occur in humans, so what sequelae will this disease cause in animals?

Sequelae of canine distemper:

Type of disease

It can be mainly divided into five characteristic types: hyperacute, acute, gastrointestinal symptoms, neurological symptoms, and skin symptoms. The clinical symptoms are mainly limited to the upper respiratory tract, so coughing and runny nose will be obvious.

Incubation period

The incubation period of canine distemper varies greatly depending on the source of infection. The incubation period from the same species is 3-6 days. The incubation period of infections originating from different species can sometimes be as long as 30 to 90 days.

Main symptoms

The initial infection of CDV begins with the virus invading the epithelial cells of the upper respiratory tract. The virus quickly spreads to local lymphoid tissue, tonsils, and bronchial lymph nodes. CDV then spreads to epithelial tissues and the central nervous system during the first week of infection. The humoral immune response after infection is associated with viral clearance. Dogs that recover from acute CDV infection are likely to have immunity for several years. When a dog that has not acquired effective immunity is infected, the virus will quickly spread to the skin, endocrine glands, digestive tract, respiratory tract, and urogenital tract.

Although canine distemper virus can damage many organs of dogs and manifest complex and diverse clinical symptoms, the main symptoms of canine distemper are usually divided into the following three aspects: respiratory symptoms, gastrointestinal symptoms and nervous system symptoms. Compared with symptoms of other organs, skin symptoms should be considered mild and can also be classified as complications. There is no canine distemper virus that only damages the skin, or even causes severe skin symptoms without damaging other internal organs. Chinese veterinary medicine believes that skin symptoms are only one of the external manifestations of canine distemper during the course of the disease. If a dog only has some skin symptoms, Chinese veterinarians will not diagnose it as having plague. If a dog has only some skin symptoms but is otherwise normal and does not show other symptoms until the skin disease is cured, it is diagnosed as canine distemper.

The neurological symptoms caused by CDV are obviously progressive and eventually deteriorate rapidly. Neurosis appears 1 to 3 weeks after recovery from acute infection. 50%~70% of CDV infections present as subclinical symptoms, including fatigue, anorexia, fever, and upper respiratory tract infection.
