FeLV and FIV in Germany

Gleich SE, Krieger S, Hartmann K. Prevalence of feline immunodeficiency virus and feline leukaemia virus among client-owned cats and risk factors for infection in Germany. J Feline Med Surg. 2009;11(12):985-992.

This study determined prevalence and risk factors for retrovirus infection in a large population of cats in Germany over a 10-year period. Client-owned cats (17,462) were tested for the presence of feline immunodeficiency virus (FIV) antibodies or feline leukaemia virus (FeLV) antigen. A subset of 100 cats was evaluated to determine their survival times. Of the 17,289 cats, 563 tested positive for anitibodies against FIV. The prevalence was 3.2% and did not change significantly between 1993 and 2002. FeLV antigen was found in 638 cats. The prevalence of FeLV decreased significantly during this time from 6% to 1%. Forty-two cats were positive for both viruses. Living in a multi-cat household did not influence the risk of retroviral infection. Risk factors for FIV infection were male gender, older age, mixed breed, access to outdoor, aggressive behavior, and FeLV co-infection. Risk factors for FeLV infection included contact with other cats, aggressive behavior, and FIV co-infection. Vaccination and testing programs appear to be effective in decreasing FeLV infection. The median survival time of FIV-infected cats was not significantly different from non-infected cats. FeLV-infected cats had significantly shorter median survival times than non-infected cats. [VT]

Prevalence of FeLV and FIV in Canada

Little S, Sears W, Lachtara J et al: Seroprevalence of feline leukemia virus and feline immunodeficiency virus infection among cats in Canada, Can Vet J 50:644, 2009.

Feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) are two of the most important infectious diseases of cats worldwide. Many studies have evaluated the prevalence of FeLV and FIV in North American cats, but very little data has been available for Canada. Veterinary clinics, animal shelters, cat rescue programs, and feral cat programs in Canada were invited to participate in the study. Enrolled participants were requested to submit the results of FeLV and FIV testing performed between Aug. 1 and Nov. 15, 2007. Information collected on each cat tested included location of testing, age, gender, access to outdoors, and whether the cat was ill at the time of testing. A total of 343 vet clinics and 13 shelters/rescue groups representing all Canadian provinces participated. Complete results were received for 11,144 cats of which 4.3% were positive for FIV and 3.4% were positive for FeLV. The seroprevalence of FeLV and FIV in this study was higher than in a recent similar study of predominantly US cats (FIV 2.5%, FeLV 2.3%). [SL]
