![]() If only the hindlimbs are affected, these kids have been seen to pull themselves around with their forelimbs. Eventually, the animal is unable to rise to a standing position. A gradual paresis and paralysis, more commonly affecting the hindlimbs and often progressing to the forelimbs, can occur. The kids may show incoordination and inappropriate placement of limbs while standing and walking. ![]() The encephalitic form of CAE viral infection most commonly affects kids between 2 and 6 months of age. Eventually these signs lead to a painful arthritis. More severe arthritic signs can include acute swellings without pain upon palpation joints that are drained of the fluid simply refill. Subtle signs include stiffness, shifting leg lameness, decreased ambulation, weight loss, reluctance to rise, and abnormal posture after rising. Early arthritic signs may be subtle or severe. All synovial membranes can be affected by CAE virus, and the number of joints affected in any one animal can vary. Joints that are commonly affected (in descending prevalence) include: carpal joints, tarsal joints, stifle joints, fetlock joints, alantooccipital joint, and coxofemoral joints. “Most goats infected with CAE virus are asymptomatic, but there are five major clinical presentations associated with viral infection including arthritis, encephalitis, interstitial pneumonia, mastitis, and progressive weight loss.9,16 The arthritic form of CAE viral infection is the most common manifestation of the disease and is generally observed in sexually mature goats (6 months and older).12,16 The arthritis tends to be chronic and progressive, though there have been reports of a sudden onset of lameness. I don’t usually quote large sections of information from other sources, but I wanted people to be aware of the severity of CAE symptoms, so I’m directly quoting this information on the symptoms of CAE from the Veterinary Clinical Pathology Clerkship Program from the University of Georgia: It is not passed from feces, breeding, or sharing food and water. ![]() Goats pass CAE to each other via infected colostrum, milk, or blood. It is a virus that affects goats and not humans. ![]() CAE stands for Caprine Arthritis Encephalitis. ![]()
