Brazil ranks 19th among the top 20 countries with the largest goat populations, with 12.9 million goats, primarily located in the Northeast, according to the 2023 Municipal Livestock Survey by IBGE. However, goat farmers face challenges with lentiviruses, particularly Caprine Arthritis Encephalitis (CAE), which is endemic in goat herds in Brazil. This disease, transmitted through colostrum, milk, and direct contact, causes arthritis, mastitis, encephalitis, and significant weight loss. Despite the lack of a vaccine, control measures are available to prevent its spread. Clinical signs of CAE include respiratory and neurological symptoms, and a reduction in milk production and quality.

Lentiviruses that affect small ruminants (LVPR) at a national level are among the main diseases that producers should be aware of. These lentiviruses are caused by viruses of the genus Lentivirus, of the Retroviridae family. Maedi-Visna is more common in sheep, but can also affect goats. In recent years, Maedi-Visna has been sporadic in goat herds in Brazil, with a lower prevalence compared to sheep. From an epidemiological point of view, transmission occurs mainly through close contact between infected and ...
