·         Are most commonly found in school age children

·         Spread is fecal-oral and is spread by touching contaminated food, clothes or other items that are contaminated with eggs and then touching the mouth or face

·         Female worms cause the symptoms, when they migrate to the anal area, especially at night.  The laying of eggs here causing intense itching, which occurs at night and often leads to difficulty with sleeping

·         Diagnosis can be made by:

o   Visual inspection of the anus- especially at night (see link for a pic (beware. .it’s gross!))



o   Tape test- placing a piece of tape on the skin around the anus.  This is analyzed under a microscope.

·         Treatment is single dose mebendazole or albendazole- these kill the worms.  It should be repeated in 2 weeks to kill any worms that have hatched since the first treatment

·         The whole family often is treated, due to easy contamination
