|q9=How can EMCV be diagnosed?
|a9= A definitive diagnosis can be confirmed by virus isolation from infected heart tissue from pigs that have died in the acute phase of the disease.
|a9= A definitive diagnosis can be confirmed by virus isolation from infected heart tissue from pigs that have died in the acute phase of the disease.
Detection of antibody specific to EMCV from still born piglets has been used to confirm foetal infection.

Within heart tissue:
*Myocarditis
*Myocarditis
*Focal or diffuse accumulation of mononuclear cells
*Focal or diffuse accumulation of mononuclear cells
*Vascular congestion and oedema
*Vascular congestion and oedema
*Degeneration of the myocardial fibres with necrosis and occasional mineralization of necrotic heart muscle.
*Degeneration of the myocardial fibres with necrosis and occasional mineralization of necrotic heart muscle.
*Brain tissue congestion, meningitis, perivascular infiltration (mononuclear cells) and neuronal degeneration.
Within brain tissue:
*In foetuses nonsuppurative encephalitis and myocarditis have been seen
*Congestion
*Meningitis
*Perivascular infiltration (mononuclear cells)
*Neuronal degeneration
Within foetuses:
*Nonsuppurative encephalitis
*Myocarditis

|q12=What treatment is there for encephalomyocarditis?
|a12=There is no specific treatment. Mortality levels in at risk pigs can be reduced by avoiding stress or excitation.

|q13=How can EMCV be controled?
|a13=
*Inactivated vaccine(intramuscularly)in the USA. *Control rodent populations on farm to prevent the spread of disease and contamination of feeds or water supply
*Good husbandry and hygiene protocols should be followed
*Regular use of disinfectants
