Clustering of cases of feline lymphosarcoma (LSA) has been observed by veterinarians for many years. In 1964 it was discovered that feline LSA was caused by an oncornavirus, the feline leukemia virus (FeLV). In 1970, a simple, indirect immunoflourescent antibody (IFA) test for FeLV was developed which enabled large numbers of cats, living in their natural (household) environments, to be tested for the virus. In one study, over 2,000 cats were tested and the results showed conclusively that FeLV is a contagious agent for cats. This finding was independently confirmed by several other investigators using different testing procedures. After discovering the contagious nature of FeLV a test and removal program was devised which successfully prevents the spread of FeLV and the development of FeLV diseases in the pet cat population. There is, at present, no evidence that FeLV infects humans living with FeLV infected cats.
多年来，兽医们一直观察到猫淋巴肉瘤（LSA）病例存在聚集现象。1964年，人们发现猫LSA是由一种肿瘤病毒——猫白血病病毒（FeLV）引起的。1970年，开发出了一种简单的间接免疫荧光抗体（IFA）检测法来检测FeLV，这使得大量生活在自然（家庭）环境中的猫能够接受病毒检测。在一项研究中，对2000多只猫进行了检测，结果确凿地表明FeLV是猫的一种传染性病原体。其他几位研究人员使用不同的检测程序独立证实了这一发现。在发现FeLV具有传染性后，制定了一项检测和清除计划，该计划成功地防止了FeLV在宠物猫群体中的传播以及FeLV疾病的发生。目前，没有证据表明FeLV会感染与感染FeLV的猫生活在一起的人类。
