Signs and Symptoms

The usual signs of endocarditis are prolonged fever for several days (occasionally up to 30 days) in a child with congenital heart disease that occurs after a procedure in the mouth, intestinal tract or urinary tract. However, the infection may occur without a previous procedure.

Symptoms of endocarditis may develop slowly or come on suddenly. They include:

  • Fatigue
  • Fever
  • Headache
  • Joint inflammation or pain
  • Night sweats
  • Poor appetite and/or weight loss
  • Rash

More severe symptoms include:

  • Anemia
  • An enlarged spleen
  • Bleeding that causes small dark lines under the fingernails or small dark spots on the skin
  • New heart murmurs
