Canine parvovirus (also referred to as CPV, CPV2, or parvo) is a contagious virus mainly affecting dogs and wolves. CPV is highly contagious and is spread from dog to dog by direct or indirect contact with their feces. Vaccines can prevent this infection, but mortality can reach 91% in untreated cases. Treatment often involves veterinary ...
Human infectious diseases may be characterized by their case fatality rate (CFR), the proportion of people diagnosed with a disease who die from it (cf. mortality rate).It should not be confused with the infection fatality rate (IFR), the estimated proportion of people infected by a disease-causing agent, including asymptomatic and undiagnosed infections, who die from the disease.
Up to 80 percent of dogs infected will have symptoms, but the mortality rate is only 5 to 8 percent. [5] Infectious canine hepatitis is a sometimes fatal infectious disease of the liver. [6] Canine herpesvirus is an infectious disease that is a common cause of death in puppies less than three weeks old. [7]
Canine parvovirus causes severe illness in dogs, the most common symptom being hemorrhagic enteritis, with up to a 70% mortality rate in pups but usually less than 1% in adults. [21] Feline parvovirus, a closely related virus, [22] likewise causes severe illness in cats along with panleukopenia.
The canine parvovirus, which causes death by dehydration, electrolyte imbalance, and endotoxic shock or sepsis, is largely survivable in wolves, but can be lethal to pups. Wolves may catch infectious canine hepatitis from dogs, though there are no records of wolves dying from it.
Left untreated, bubonic plague will have a CFR of up to 60%. [21]: 57 With antibiotic treatment, the CFR for bubonic plague is 17%, pneumonic 29% and septicaemic 45%. [22] [23] Active tuberculosis, the infection with the highest mortality rate, has a CFR of 43% in the absence of HIV. [24] [25]
Carnivore protoparvovirus 1 is a species of parvovirus that infects carnivorans.It causes a highly contagious disease in both dogs and cats separately. The disease is generally divided into two major genogroups: FPV containing the classical feline panleukopenia virus (FPLV), and CPV-2 containing the canine parvovirus type 2 (CPV-2) which appeared in the 1970s.
A more serious complication of canine coronavirus occurs when the dog is also infected with canine parvovirus. Coronavirus infection of the intestinal villi makes the cells more susceptible to parvovirus infection. This causes a much more severe disease than either virus can separately. [7]
