Translation Traps (for Russian speakers)

Common Mistakes
- Misspelling 'an(a)emia'.
- Confusing it with 'equine influenza' or other equine diseases.
- Using it in non-equine contexts (it is specific to horses, donkeys, mules).

FAQ
Frequently Asked Questions
No, equine infectious anemia virus (EIAV) is not zoonotic. It only affects equines like horses, donkeys, and mules.
There is no cure and no commercially available vaccine in most countries. Infected animals remain carriers for life. Control is based on testing and segregating or euthanizing positive animals.
The Coggins test is the standard agar gel immunodiffusion (AGID) blood test used to diagnose equine infectious anemia by detecting antibodies to the virus.
Protocols vary by region, but typically the horse must be permanently identified, isolated from other equines (at least 200 yards), or euthanized. It cannot be sold or moved without special permits.
