I don't believe you have to eat the eggs (just the thought of if makes me shudder)
There was a tv programme on last night (UK) where a Dr was used to show how you get infected.A few droplets of water was placed on his arm(containing 50 microscopic worms) With a magnified focus they showed the worms burying into the skin (they belive the worms secrete an enzyme which allow them to do this) They then went on to talk about side affects like itchiness where they enter the skin and the host developing a cough. Next week they will be showing the host's intestinal tract(via camera) to show what happens next. It is only an approx 5/10 minute piece in a programme but interesting never the less.
