What are the symptoms of a sudden canine distemper outbreak in a fox group?
In the early stage, the sick animal's body temperature rises (40°C to 41°C), with listlessness, reduced food intake, sometimes vomiting, and a dry nose. Two to three days after onset, the typical clinical symptoms of canine distemper appear: the conjunctiva begins to become congested and swollen, progressing finally to purulent conjunctivitis, with hair loss around the eyes; in severe cases, the upper and lower eyelids are stuck together by purulent discharge. The skin of the nose becomes cracked, the nasal mucosa becomes inflamed and swollen, and purulent discharge flows out, blocking the nostrils and causing difficulty breathing. When the lungs are affected, coughing occurs, initially a dry cough and later a wet cough, and at the same time catarrhal inflammation develops in the digestive organs, with diarrhea, sometimes mixed with blood.
During the recovery period of the disease or right at the onset of fever, neurological symptoms appear. Spasms, epileptic seizures, increased responsiveness to stimuli, and sometimes frenzy. Sick animals that show neurological symptoms from the very beginning mostly follow an acute course, with a short disease duration, dying within 1 to 2 days.
