3. Procedure Blood is collected from suspected animal. Detects antibodies to the major group-specific antigen [p26] of EIA virus. Results are valid for 6 months or 1 year from the date the blood is collected. It detects all infected animals except those in the early incubation period. A horse suspected of being exposed should be retested after 4 to 6 weeks. 12-09-2020 ABHIJITH SP CVAS POOKODE 3

4. Facts This is a virus that can cause affected horses (or donkeys) to have fevers, anemia (low red blood cell count), edema (stocking up), or weight loss/muscle wasting. Some horses recover quickly from the symptoms, which may be nothing more than a fever for <24 hours. EIA is a relative of the virus that causes HIV in humans. Horses that become infected will carry the disease for life. These carriers often show no signs of disease and appear healthy. Carriers then serve as a source of disease transmission to other horses. 12-09-2020 ABHIJITH SP CVAS POOKODE 4

5. Facts EIA is transmitted by flies (horse flies and deer flies), so your horse doesn’t actually have to come into contact with an infected or carrier horse to catch the virus. Flies come to your farm, so your horse is at risk even if he never travels, or lives in a closed herd. There is no vaccine for EIA and there is no treatment. Control horse fly and stable fly.
