Canine coronavirus

Affects: Dogs

Overview

Canine coronavirus (CCoV) is an enveloped, positive-sense, single-stranded RNA virus which is a member of the species Alphacoronavirus suis. It is distributed world wide and may cause intestinal disease in dogs. The infecting virus enters its host cell by binding to the APN receptor. It was discovered in 1971 in Germany during an outbreak in sentry dogs. The virus is a member of the genus Alphacoronavirus and subgenus Tegacovirus.

Signs & Symptoms

Symptoms, Diagnosis, Treatment, And Control: The incubation period is one to three days. The disease is highly contagious and is spread through the feces of infected dogs, who usually shed the virus for six to nine days, but sometimes for six months following infection. Symptoms include diarrhea, vomiting, and anorexia. Diagnosis is through detection of virus particles in the feces. Treatment usually only requires medication for diarrhea, but more severely affected dogs may require intravenous fluids for dehydration. Fatalities are rare. The virus is destroyed by most available disinfectants. There is a vaccine available (ATCvet code: QI07AD11 (WHO)), however, evidence suggests its use may be very limited to specific cases. It is generally not recommended for use, due to questions around its efficacy and the general timing of most vaccinations. It was historically recommended in puppies and show dogs.
