Feline leukemia virus (FeLV) is a retrovirus that infects cats. (wikipedia.org)
FeLV can be transmitted from infected cats when the transfer of saliva or nasal secretions is involved. (wikipedia.org)
Because FeLV is cat-to-cat contagious, FeLV+ cats should only live with other FeLV+ cats. (wikipedia.org)
FeLV is categorized into four subgroups, A, B, C and T. An infected cat has a combination of FeLV-A and one or more of the other subgroups. (wikipedia.org)
Although it is thought that virus protein has to be present to induce lymphomas in cats, newer evidence shows that a high percentage of FeLV-Antigen negative lymphomas contain FeLV-DNA, indicating a "hit-and-run" mechanism of virus-induced tumor development. (wikipedia.org)
Once the virus has entered the cat, there are six stages to a FeLV infection[citation needed]: Stage One: The virus enters the cat, usually through the pharynx where it infects the epithelial cells and infects the tonsilar B-lymphocytes and macrophages. (wikipedia.org)
Cats infected with FeLV can serve as sources of infection of FeLV-A. Cats can pass the virus between themselves through saliva and close contact, by biting another cat, and (rarely) through a litter box or food dish used by an infected cat. (wikipedia.org)
Once a cat has been infected with FeLV-A, additional mutated forms of the original FeLV-A virus may arise, as may FeLV subgroups B, C and T. In addition to domestic cats, some other members of Felidae are now threatened by FeLV (e.g. lynx and Florida panther). (wikipedia.org)
Approximately 0.5% of pet cats are persistently infected with FeLV, but many more pet cats (>35%) have specific IgG antibodies which indicate prior exposure and subsequent development of immunity instead of infection. (wikipedia.org)

Background - Feline leukemia virus (FeLV) is a retrovirus related to murine leukemia virus that has existed among feral cats for tens of thousands of years before its discovery in 1964 (Jarrett, et al. (treatfip.org)
1964). FeLV infection occurs mainly among cats under 3-8 years of age (reviewed Pedersen, 1998, 1991). (treatfip.org)
1977). FeLV infection in nature usually occurs after cats are old enough to socialize and the primary phase of infection is either inapparent or transient and ends with a long-lasting immune response in 95% or greater of cats. (treatfip.org)
FeLV-associated diseases occur predominantly in the small group of cats with persistent infection. (treatfip.org)
FeLV disease in feral cats raised no alarms prior to its discovery and any associated mortality went unappreciated among the spectrum of maladies befalling feral cats. (treatfip.org)
Therefore, what we know about the pathogenesis of FeLV infection in feral cats initially came from studies done in the 1970's and 1980's on groups of household cats and laboratory infections (reviewed Pedersen, 1998, 1991). (treatfip.org)
Epizootiology - FeLV appears to have entered unknowingly into owned cat populations from nature prior to the 1960's and rapidly increased in incidence. (treatfip.org)
FeLV was identified as a major cause of disease in owned cats, retrospectively in the 1960s and prospectively in the 1970's and 1980's. (treatfip.org)
What caused the panzootic of FeLV infection and disease among owned cats? (treatfip.org)
The end of the FeLV panzootic came with the widespread "testing and removal" of viremic cats as documented by Weijer and colleagues (1986). (treatfip.org)
It is noteworthy, that FeLV infection is no longer a major disease problem in managed multi-cat situations and household pets. (treatfip.org)
Cats with persistent FeLV infection will ultimately develop several primary and secondary diseases that are usually fatal. (treatfip.org)
Since infection in nature occurs mainly in younger cats, and most die within 3 years, few FeLV infections in nature are seen in cats older than 5-8 years. (treatfip.org)

Feline leukemia, or FeLV, is a virus that is the second leading cause of death in cats. (catster.com)

Another rare transmission can happen when fleas from a FeLV-infected cat bites a FeLV-negative cat. (catster.com)
When the IFA test comes back positive, it usually indicates a more advanced stage of the virus and can mean that your cat is infected with FeLV for the rest of their life. (catster.com)
