I have heard that there are unseen sandworms that can burrow into your feet on the beaches there and can cause some pretty extensive damage. My aunt had a friend who had one burrow into her foot and she didn't even notice until she started having foot problems about 3 weeks later. Any news on this?
Larvae migrans -- 'dog hookworm'. They come from dogs, live in the sand, enter humans or animals via the skin,cause an itchy rash that is characterized by a track as the worm travels under the skin, are microscopic, and are easily treated.
