EVH-1......Press Release.......What is an "index farm"
Just saw the press release about the horse with EVH-1 on COTH (and other press releases). It says the horses in barn 7 at HITS have been quarantined...and the local "index farm".
I know folks there and am aware of the situation at the showgrounds, but what is a "local index farm" (where the horse came from, yet unnamed?).
It's sort of the equivalent of "Patient Zero" - the initial farm that indicates an outbreak (in this case, the farm where the horse shipped in to the show from), and the horse that was the first to show symptoms and start all this would be the index case.
