FELINE IMMUNODEFICIENCY VIRUS: AN EVIDENCE-BASED CLINICAL REVIEW OF NATURALLY-ACQUIREDINFECTION

摘要

Worldwide prevalence of feline immunodeficiency virus (FIV) varies from 1 to 31% in healthy cats and is generally higher in sick cats, but the exact prevalence depends on the study design used. In a US-based study, Levy et al. surveyed 345 veterinaryclinics (FTV-positives - 3.1% of 9970 cats) and 145 animal shelters (FIV-positives - 1.7% of 8068 cats; Levy, 2006). Prevalence figures for Canada and Japan are as follows: Canada - 4.3% of 11,144 cats tested in 2007 (Little, 2011); Japan - 23.2% of 1770outdoor cate(Nakamura, 2010). The major risk factors for FIV infection are as follows: Age - adu Gender - male (MN 4.3%, MI 3.3%) and intact status; Lifestyle - free-roaming/outdoor access; and Health status - Current illness (6.1%; Levy, 2006). Of shelter cats studied by Levy et al. (2006), 1.4% were owner relinquished, 1.6% were stray and 3.9% were feral.
