Clinical manifestations of parvovirus

1. Physical symptoms appear within 3-14 days after exposure to parvovirus, with the average onset time being 5-7 days. Clinical symptoms include: loss of appetite, depression, fever, vomiting, and diarrhea.

2. Adult dogs do not necessarily have fever, but often suffer from loss of appetite, depression, vomiting and diarrhea (after 24 hours). Sometimes vomiting and diarrhea occur repeatedly.

3. The mortality rate of adult dogs is 2-3%. The mortality rate in puppies (due to shock caused by high dehydration) is 25-50%. Therefore, rehydration as early as possible is the key to treatment.

3. Died within a short period of time; some sick dogs died after mild diarrhea. Newborn puppies infected with parvovirus develop heart lesions, which can rapidly destroy the puppy's heart muscle cells. The affected dog then develops wheezing, cyanosis of the oral mucosa and skin, and sometimes sudden collapse and death are the only physical symptoms of the disease in puppies. Puppies that tolerate it can still die of the disease weeks or even months after infection due to permanent myocardial damage.

Methods of transmission of parvovirus

1. Parvovirus can be transmitted through feces. Most parvovirus outbreaks occur in parks, dog fairs, kennels, pet hospitals and other places where dogs gather. Although humans are not infected with parvovirus, fecal-contaminated shoes also play a role in spreading the disease.

2. Dogs that have not been vaccinated can become ill once they are exposed to parvovirus. The virus can withstand high temperatures and can survive in soil and cages for a long time. Once infected, parvovirus is difficult to get rid of.
