Here is a good article on Equine Infectious Anemia also known as EIA and the disease the Coggins test is for. Recently in the USA an outbreak occurred from a Vet Hospital by sharing a heparinized saline (what is used for flushing and keeping catheters open). A stark reminder of the need for strong protocols that are followed.
"When a horse tests positive, all potentially exposed horses must be quarantined and retested until two negative results, taken 30 to 60 days apart, are confirmed. EIAV-positive horses must either be euthanized or permanently isolated at least 200 yards from other equids—sufficient distance to prevent mechanical transmission by insect vectors. Positive horses must also be permanently identified with a USDA-issued brand or tattoo."
Researchers warn of rising EIA cases, with inapparent carriers and iatrogenic spread posing ongoing threats to horse health nationwide.
