在一个自然的农村家猫群体中，连续6年检测猫免疫缺陷病毒（FIV）感染的患病率。性别，年龄，体重，原产地，组大小和存在的FIV抗体被记录为每个采样猫。Logistic回归被用来估计感染的记录参数的影响。FIV患病率高达19.6%，在控制样本年龄结构变化后，各年之间没有统计学变化。FIV感染的特点是与攻击性行为有关的危险因素：分散的老年成年男性更有可能被感染。对猫群大小和感染个体的空间分布的研究表明，在雄性中没有感染群，并表明漫游在FIV传播中的重要性。总之，FIV感染传播，传染性低，主要是在特别积极的个人之间，该病毒在这一人群中流行。
Prevalence of Feline Immunodeficiency Virus (FIV) infection was measured during 6 consecutive years in a natural rural population of domestic cats. Sex, age, weight, origin, group size and presence of antibodies to FIV were recorded for each sampled cat. Logistic regressions were used to estimate the influence of the recorded parameters on infection. FIV prevalence rates are as high as 19.6% in the total population, and do not statistically change between years, after controlling for changes in samples' age structure. FIV infection is characterized by risk factors linked to aggressive behaviour: old mature male adults having dispersed are more likely to be infected. A study of the cats group size and of the spatial distribution of infected individuals indicates the absence of infection clusters in males, and suggests the importance of roaming in the spreading of FIV. In conclusion, FIV infection spreads, with low contagiousness, mainly between particularly aggressive individuals, and the virus is endemic in this population.
