Division C SUBACUTE FORMS

Subacute forms of the disease are more common in endemic areas. Subacute infection is characterised by fluctuating fever, depression and pneumonia. Death may occur due to heart failure. Lesions in subacute forms are similar to those in the acute form but milder. Characteristic lesions are large haemorrhages in the lymph nodes, kidneys and spleen, pulmonary congestion and oedema and in some cases interstitial pneumonia.
