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]
Strangles (also called equine distemper) is a contagious upper respiratory tract infection of horses and other equines caused by a Gram-positive bacterium, Streptococcus equi. [1] As a result, the lymph nodes swell, compressing the pharynx , larynx , and trachea , and can cause airway obstruction leading to death, hence the name strangles. [ 2 ]
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.
In horses, which are most commonly infected, this bacterium causes an upper respiratory tract infection (along with the other symptoms). This infection causes a highly contagious and deadly disease in horses. This will be caused by spreading of nasal discharge or lymph nodes in feed troughs, bedding, etc. [12]
The name equine encephalosis is misleading as the disease is not primarily a neurological disorder.Although the majority of infections result only in mild clinical signs, in more severe cases clinical signs include a short period (typically two to five days) of fluctuating fever, accompanied by varying degrees of inappetence.

EIA-positive horses are infected for life. Options for the horse include sending the horse to a recognized research facility, branding the horse and quarantining it at least 200 yards from other horses for the rest of its life, and euthanizing the horse. Very few quarantine facilities exist, which usually leads to the option of euthanizing the ...
Following infection, the first sign is fever, [7] peaking at 41 °C (106 °F), [8] followed by various signs such as lethargy, [7] nasal discharge, [8] "pink eye" (conjunctivitis), [7] swelling over the eye (supraorbital edema), [7] urticaria, [4] and swelling of the limbs and under the belly (the ventral abdomen) which may extend to the udder ...
Anaplasmosis can also be referred to as "yellow bag" or "yellow fever" because the infected animal can develop a jaundiced look. Other signs of infection include weight loss, diarrhea, paleness of the skin, aggressive behavior, and high fever. [2] Many different tick species can carry the bacteria that cause anaplasmosis.
