chapter-378 PREVALENCE AND RISK FACTORS 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 veterinary clinics (FIV-positives, 3.1% of 9970 cats) and 145 animal shelters (FIV-positives, 1.7% of 8068 cats).9 Prevalence figures for Canada and Japan are as follows: Canada – 4.3% of 11,144...
