Thread-worms creating serious health issues
A friend of mine is very anxious about the health of her child as the child is suffering from thread-worms for a very long time. He is five years old. She has seen many doctors but the worms keep coming back in two-three months time. Please suggest some good medicine. Should she take some precautions to keep her child free of these nasty worms? She takes care of general cleanliness though. The child is becoming weak day by day. Please help.
