 +
*Abnormal behaviour/aggression
 +
*Coma
 +
 +
In piglets:
 +
*Changes in hair coat (dull/rough)
 +
*Ocular erosions
 +
*Enlarged distended bladder
 +
*Constipation/reduction in faces or diarrhoea
 +
|l9=Blue Eye Disease#Clinical Signs
 +
|q10=What clinical signs are associated with boars?
 +
|a10=
 +
*Male infertility
 +
*Lack of libido
 +
*Haemospermia
 +
*Orchitis with epidydimitis
 +

 +
|l10=Blue Eye Disease#Clinical Signs
 +
|q11=What is the epidemiology of Blue eye disease?
 +
|a11=
 +
*The virus is spread via direct contact, fomites and possibly birds
 +
*Virus can be found in the axon of neurons
 +
*Original site of replication is thought to be the nasal mucosa and tonsils
 +
*It can be found in tissues (lung, liver, spleen, kidney, lymph node, heart and testis)
 +
*Hematogenous spread is likely
 +
|l11=Blue Eye Disease#Epidemiology
 +
|q12=What is the distribution of Blue eye disease in pigs?
 +
|a12=The disease appears restricted to Central Mexico and its states.
 +
|l12=Blue Eye Disease#Distribution
 +
|q13=What is the treatment for Blue eye disease?
 +
|a13=
 +
*No treatment is available for Blue eye disease
 +
*Supportive medication for respiratory and inflammatory disease should be administered
 +
*Euthanasia may be necessary for ataxic pigs.
 +
|l13=Blue Eye Disease#Treatment
 +
|q14=How is Blue eye disease controlled?
 +
|a14=
 +
*The disease is self limiting
 +
*Closed herds once infected will have sporadic outbreaks of the disease
 +
*There is no approved vaccine for the control of blue eye disease
 +
*Elimination can be achieved by:
 +
**Closed herds
 +
**All-in/all-out systems
 +
**Good washing and disinfecting protocols
 +
