New York animal health authorities have identified no additional cases of equine infectious anemia (EIA) in the state after 11 Cortland and Cayuga county horses tested positive for the disease earlier this year.
The all-clear came on Aug. 10 after a five-month investigation by the  New York State Department of Agriculture and Markets' Division of Animal Industry according to a statement the agency issued to the Equine Disease Communication Center. 
State authorities have released all related farms from quarantine.

Equine infectious anemia, also known as “swamp fever,” is a viral disease that attacks horses' immune systems and is most commonly detected with the Coggins test. The virus is transmitted through the exchange of body fluids from an infected to a noninfected animal, often by blood-feeding insects such as horseflies, and more rarely through the use of blood-contaminated instruments or needles.
Once an animal is infected with EIA, it's infected for life and can serve as a reservoir for the spread of disease. Obvious clinical signs of the disease include progressive loss of condition along with muscle weakness and poor stamina. An affected horse also could show fever, depression, and anemia.
The United States Department of Agriculture and state animal health regulatory agencies require euthanasia or strict lifelong quarantine for horses testing positive for EIA.
