Background

Size

• Roundworm eggs range in size from several hundredths of an inch (microscopic) to 3 to 4 inches long and can be seen by the naked eye.

Symptoms

• There are no symptoms in most cases; however, if symptoms occur they may include bloody sputum, passing worms in stool, vomiting worms, stomach pain, shortness of breath, signs of malnutrition and coughing.
