How did a 3 year old contract threadworms?
I read an article describing how this mother’s three year girl kept scratching herself “down there”. Her mother thought it was nothing to worry about. The “itch” did not go away and the mother took her daughter to a doctor. The doctor told the woman that her daughter had threadworms. Question: what the heck are threadworms and how did a 3 year old child contract such worms?
