Parvovirus can survive in the environment for 3 to 6 months, so you should keep a dog regularly. If you still want to keep a dog, it is best to keep it after 3 months, and you must clean it with disinfectant and irradiate it with ultraviolet rays. After all, furniture and sofas can't be thrown away, and it's not convenient to spray disinfectant.
Parvovirus is a virulent infectious disease, which is highly contagious to dogs. This virus is a great threat to life, so we must pay attention to cleaning the surrounding environment, and immediately dry it and keep it dry.
Canine parvovirus has strong resistance to external factors. The virus can survive for 65,438+0 hours at 60~C and endure for 30 minutes at 80 ~ C. The virus is still infectious in acidic environment (hydrogen ion concentration of 65,438+0,000 micromoles/liter, i.e. pH3) and alkaline environment (hydrogen ion concentration 1 mmol/liter, i.e. pH9).
Extended data:
1978 Kelly in Australia and Thomson in Canada isolated canine parvovirus from the feces of dogs with enteritis. Since the virus was discovered, it has been prevalent all over the world and is one of the most serious infectious diseases that harm dogs.
After healthy dogs are infected with the virus through the digestive tract, the virus mainly attacks two kinds of cells, one is intestinal epithelial cells and the other is myocardial cells, which show gastrointestinal symptoms and myocarditis symptoms respectively. Myocarditis is more common in puppies.
CPV mainly infects dogs, especially puppies, with strong infectivity and high mortality. It can happen all year round, especially in winter and spring. Sudden changes in feeding and management conditions, long-distance transportation and cold crowding can all promote the occurrence of this disease.
Sick dogs are the main source of infection, and there are a lot of viruses in vomit, saliva and feces. Rehabilitation dogs can still detoxify through feces for a long time. There is evidence that people, lice, flies and cockroaches can become mechanical carriers of CPV. Healthy dogs are in direct contact with sick or poisoned dogs, or contaminated feed and drinking water are infected through the digestive tract.
