A dream trip that turns into a nightmare because of a phenomenon of "larva migrans". A couple of young Canadians on vacation on the island of the Dominican Republic have seen their feet infested with a parasite, hookworm, which mainly affects dogs and cats. As the parasite can not go into the human blood, it seeps under the skin, causing this very unpleasant phenomenon.
A young Canadian couple had the unpleasant surprise of suffering from severe itching and pain in their feet and toes when returning from vacation in the Dominican Republic. The itching was then accompanied by painful swelling and blisters, impeding walking, and revealing dozens of worms hookworm type.
If hookworms can infect humans, this is only a "parasitic impasse": the worm can not be reproduced in humans, or pass into the blood or lymph and then we observe a phenomenon of "cutaneous larva migrans" near the entrance of the worm into the body: the worm remains under the skin, where it moves a little, creating violent local reactions and itching.
A larva migrans
Also known as "rampant verminous dermatitis" or "creeping pseudomyiasis", this dermatological condition is caused by the penetration into the skin of larvae of a parasite, in this case hookworms.
Hookworms are parasites of dogs and cats (and other wildlife) and are found in their droppings. Young Canadians have likely caught these pests by walking barefoot on a beach polluted with animal dung.
Frequent in tropical zones, these anlylostomes cling to the epidermis and then penetrate by perforating the skin. That's what happened to this couple of Canadians on vacation on the island of the Dominican Republic. As reported by the International Business Times, they began to feel itchy in their feet after a walk on the beach, then intense pain when they returned to Canada.
"I have a dozen worms in my feet"
It was finally the fourth doctor they consulted who made the diagnosis. In humans, the parasite can not pass into the blood or lymphatic system to start the reproductive process: the larvae are thus trapped under the skin. They move a little, producing this phenomenon of larva migrans, and eventually die there, after causing severe itching and burning, even infections.
"I have a dozen worms in my feet, Katie too, it makes me sick to think about it, it's pretty disgusting, it's something that lives in your body and is not supposed to be there." , told Eddie Zytner (25) at the International Business Times. The pictures published by the couple on Facebook speak for themselves.
"Three of the four doctors we consulted had never heard of these parasitic worms, so if your feet start scratching or swelling like mine, go get them examined," the young man advises on the social network. "All this while walking barefoot on the beach so anyone who travels, check your resort and see if the beaches are clean, it is better to wear shoes on the beach as much as possible".
Larvae sensitive to soil vibrations
It is in 1874 that this dermatosis is discovered, after the examination of a little African-American girl. Over the course of the studies, it is understood that the eggs are released by the stool and that in a favorable environment, that is to say hot and humid, the larvae hatch in 1 or 2 days. In 5 to 7 days they become filariform larvae of 3e stage and infesting. Sensitive, they are very attracted by the vibrations of the ground, which explains that they attack the feet. So be careful.
