Feline ownership is popular and represents the largest segment of the pet population in Malaysia. Most feline owners own, on average, 2-3 cats, with some having >10 cats per household. Feline immunodeficiency virus (FIV) and feline leukaemia virus (FeLV) are two clinically important viral infections in cats. Documenting the prevalence of these diseases in the feline population is important for both veterinarians and the public.


This was a retrospective study, using data collected from the domestic cat population seen at a 24 h private veterinary hospital in Malaysia, to determine the prevalence of FIV and FeLV in an urban area and risk factors associated with these infections. Between 2010 and 2016, 2230 blood samples were collected and tested for FIV antibodies and FeLV antigen using commercially available ELISA test kits.


In total, 10.0% (n = 224; 95% confidence interval [CI] 8.80-11.26) were seropositive for FIV; 12.0% (n = 267; 95% CI 10.62-13.32) were seropositive for FeLV; and 2.6% (n = 58; 95% CI 2.01-3.17) were seropositive for both.

Conclusions and relevance:

The prevalence of FIV is lower and FeLV higher than previously documented for this region. Because of the immunosuppressive potential of both viruses, client education and use of appropriate control strategies such as routine screening, vaccination and eradication should be considered.
