Caprine arthritis encephalitis virus Caprine arthritis encephalitis virus Caprine arthritis encephalitis virus (CAEV) is a retrovirus which infects goats and cross-reacts immunologically with HIV, due to being from the same family of viruses. CAEV cannot be transmitted to humans, including through the consumption of milk from an infected goat. There is no evidence that CAEV can cure HIV in humans. CAEV is commonly transferred within the goat species by ingestion of colostrum or milk from an infected goat, and to a less extent, cross species CAEV transfer by sheep is possible . CAEV adversely affects the immune system of its host, causing a disease
