Well, I've always been told that horses who travel extensively and between a lot of states should have a coggins test done every 6 months. Because of what you've said, MIE. But, like Speed Racer pointed out, if we can make sure there are no new infected horses each year, then your horse has a very very very slim chance of contracting it.
The mosquito or fly would have to bite an infected horse and then fly a LONG way to bite your horse. Because the disease doesn't come from the insect, itself. Rather the insect is just a carrier, it would have to have bitten an infected horse. So, if there are no infected horses within miles of you, your horse should be fine.
EIA used to run rampant during the early 1900s up until the 60s, so the test is extremely effective when you look at the small number of infected horses nowadays.
