Naturally acquired feline immunodeficiency virus (FIV) infection in cats from western Canada: Prevalence, disease associations, and survival analysis.
This retrospective study evaluated epidemiologic features and disease associations of feline immunodeficiency virus (FIV) infection in client owned cats from western Canada. Among 1205 cats that were tested 66 (5.5%) were positive for FIV antibody (FIV(+)) with a higher prevalence in males than females. FIV(+) cats were older than the overall population. Epidemiologic features and disease associations were compared between 58 FIV(+), but feline leukemia virus negative (FeLV(-)) cats and 58 age and sex matched FIV-negative (FIV(-)), FeLV(-) cats. FIV positivity was associated with a history of bite wounds, increasing age, and male gender. Lethargy and oral diseases were significantly associated with FIV positivity. Although several FIV(+) cats were euthanized, the survival time of FIV(+) cats after diagnosis was not significantly different from that of FIV(-) cats. In summary, FIV prevalence was low in cats from western Canada, clinical signs/diseases were mild, and lifespan was not different in FIV(+) cats.
