The most current theory is a result of a recent study that suggests it is caused by a pegivirus, referred to as Theiler's disease-associated virus (TDAV). [2] Eight horses that had received prophylactic botulinum antitoxin and developed subsequent signs of Theiler's disease were subjected to a test for a viral infection based on RNA sequencing techniques.
Clinical signs include cute small lesions, no bigger than 2 mm in diameter around the vulva in mares, and on the sheath in stallions. The small bumps blister and then rupture, leaving raw, ulcerated, painful sores. [1] While the majority of the symptoms are external, the presence of the virus can cause small and large plaque variants in tissues ...
Equine multinodular pulmonary fibrosis is a chronic lung disease of horses. There is evidence that the disease is caused by infection with a gammaherpesvirus , equine herpesvirus 5 . The disease affects usually adult horses reducing the ability to exercise as a result of the formation of nodular lesions in the lungs.

The signs shown depend on the horse's age, the strain of the infecting virus, the condition of the horse and the route by which it was infected. [5] Most horses with EVA infection do not show any signs; if a horse does show signs, these can vary greatly in severity. [ 6 ]
Equine influenza is characterized by a very high rate of transmission among horses, and has a relatively short incubation time of one to three days. [6] Clinical signs of equine influenza include fever (up to 106 °F [41 °C]), nasal discharge, have a dry, hacking cough, depression, loss of appetite and weakness. [6]
Mild or horse sickness fever form. Mild to subclinical disease is seen in zebras and African donkeys. Infected animals may have a low-grade fever and congested mucous membrane. The survival rate is 100%. Mixed form. Diagnosis is made at necropsy. Affected horses show signs of both the pulmonary and cardiac forms of AHS.
Chronic: The horse tires easily and is unsuitable for work. 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.
