The horse may have a recurrent fever and anemia, and may relapse to the subacute or acute form even several years after the original attack. [citation needed] A horse may also not appear to have any symptoms, yet still tests positive for EIA antibodies. Such a horse can still pass on the disease.

Covering sickness, or dourine (French, from the Arabic darina, meaning mangy (said of a female camel), feminine of darin, meaning dirty), [1] is a disease of horses and other members of the family Equidae. The disease is caused by Trypanosoma equiperdum, which belongs to an important genus of parasitic protozoa. [2]
An acute form of the disease, which is generally fatal unless treated, occurs in horses, donkeys, mules, cattle, buffalo, deer, camels, [2] llamas, dogs, [3] and cats. This form is caused by Trypanosoma evansi (Steel 1885) (Balbiani 1888), and is transmitted by horse-flies, and also by the vampire bat, Desmodus rotundus, in South-America.

Horses that develop purpura haemorrhagica usually have a recent history of strangles (infection with Streptococcus equi subsp. equi) or vaccination (intramuscular or intranasal) for strangles. It is thought to be caused by an auto-immune reaction where antibodies against the S. equi M- or R-protein cross-react with proteins on endothelial cells .
Venezuelan equine encephalitis virus is a mosquito-borne viral pathogen that causes Venezuelan equine encephalitis or encephalomyelitis (VEE). VEE can affect all equine species, such as horses, donkeys, and zebras. After infection, equines may suddenly die or show progressive central nervous system disorders. Humans also can contract this disease.
Viruses in the family Circoviridae are non-enveloped, with icosahedral and round geometries, and T=1 symmetry. [2] The diameter is around 20 nm. Genomes are circular and non-segmented, around 3.8kb in length.
