FIV in Cats: Causes, Transmission, Signs, Diagnosis, Treatment, Control

FIV in cats or Feline Immunodeficiency Virus (FIV) is one of the most important diseases of cats found throughout the world. The disease affects the immune system of cat and makes vulnerable to many other diseases. Many cats may carry the virus in their body asymptomatically and live an average lifespan. The disease is dangerous when the immune system is weak, and the cat is affected by opportunistic bacteria, viruses, or protozoa. The FIV in cats cannot cure completely, and cats can live with this virus.

Important Information About FIV

Cats are one of the lovely pets in the house. Cats are suffering from many infectious and non-infectious diseases. FIV in cats is one of the most critical diseases in the cat population. The disease spread from cats by mainly biting wounds and indirectly from contaminated food and water. There is no specific treatment and the preventive vaccine available for Feline AIDS. As a cat owner, you must be very cautious to prevent the entry of this disease into your house.

Feline Immunodeficiency Virus is the causal organism of FIV in cats. The virus is under the Lentivirus genus and Retroviridae family. The virus has simial effects to AIDS in humans causes the weakening of the host’s immune system. The virus primarily affects the white blood cells (WBC) of hosts. The host mainly dies from secondary infection by other organisms. 

Epidemiology and Transmission of Feline AIDS

FIV in cats found worldwide distribution. In the United States, 2.5-5% of healthy cats are found positive for the Feline Immunodeficiency virus. The incidence rate is more in sick cats. There is no effective vaccine against FIV available. 

The virus is primarily transmitted by the biting wound of an infected cat. The secondary transmission occurs very little by the contaminated water bowl, feed bucket, toys, grooming equipment, and household items. There is little chance of the spread of the disease from infected mothers to kittens. Sexual contact with a male cat is a less powerful method of transmission of FIV.

  • Changes in blood parameters, i.e., increased protein content in the blood.
  • Neurological disorders and seizures.
  • Loss of body weight.
  • Death of the cats due to multiple problems.

The standard diagnostic procedures of FIV are as follows:

  • History of infection to other cats.
  • The vet and owner observed specific clinical signs.
  • Chronic diseases.
  • Progressive weakness of the cat.
  • Blood parameters for protein.
  • PCR for the identification of the causative virus.
  • ELISA and CFT for serological diagnosis of FIV antibodies in cats.

  • A potential antibiotic to prevent secondary bacterial infection.
  • Fluid and electrolyte therapy to improve the body condition.

Zoonotic Importance of Feline AIDS

Feline AIDS is caused by the FIV virus very similar to HIV and causes a disease similar to Acquired Immunodeficiency Syndrome (AIDS) in cats. The virus is highly species-specific and never transmits to humans from cats. FIV only transmits from cat to cat. So as a cat owner, it would be best if you feared that this disease is your cat.
