Cat Contracts Feline Distemper After Receiving the First Vaccine Dose

Cat contracts feline distemper after receiving the first vaccine dose

This situation mainly considers that the cat has already been infected with the feline parvovirus before vaccination, or has contracted the feline distemper after receiving the first vaccine dose. The cause of the disease in the former is due to the long incubation period of the feline parvovirus after infection, while the latter is mainly due to the fact that only one dose of the vaccine has been administered, which is insufficient to produce sufficient protective antibodies.

The main considerations for contracting feline distemper after the first vaccine dose are pre-immunization infection and post-immunization infection. Because the feline distemper does not manifest immediately after infection, but has a relatively long incubation period, it is possible for the disease to occur just after the first vaccine dose. The latter situation is mainly due to the fact that one dose of the vaccine has not yet formed the ability to resist the feline parvovirus, resulting in disease manifestation. However, the cause of feline distemper in cats is almost unrelated to vaccines, as current feline distemper vaccines are all inactivated or attenuated vaccines.

Feline distemper, also known as feline panleukopenia, mainly manifests with symptoms such as vomiting, diarrhea, abdominal pain, bloody stools, and a significant decrease in white blood cell count. Due to the continuous decrease in white blood cells, the cat's ability to resist infection decreases, and it is prone to secondary bacterialemia and endotoxemia.

The diagnosis of feline distemper mainly includes clinical symptoms, diagnostic kits, and PCR examinations. By combining multiple results, a definitive diagnosis can be made.

The treatment plan for feline distemper is relatively mature. First, the cat needs to be fasting and deprived of water to prevent exacerbating vomiting. The treatment principles include suppressing virus reproduction, controlling secondary infections, stopping vomiting and bleeding, replenishing fluids, correcting electrolyte and acid-base imbalances, and providing necessary supportive treatment. For severe cases or those with very low white blood cell counts, consideration can be given to blood transfusions, plasma infusions, and other substances.
