Parasites on the skin are usually small insects or worms that burrow into the skin to live there or lay their eggs.
Dracunculosis is characterized by chronic skin ulcers. Tissue under the skin is infiltrated by developing larvae of the parasitic worm known as Dracunculus medinensis, or Guinea worm.
There are two medications that can be used to treat the infection and manage the symptoms. The treatment of choice is diethylcarbamazine (DEC), which kills the microfilariae and adult worms. Albendazole is sometimes used in patients who are not cured with multiple DEC treatments. It is thought to kill adult worms.
Larvae can become adults only inside the human body. The adult worms live between layers of connective tissue (e.g., ligaments, tendons) under the skin and between the thin layers of tissue that cover muscles (fascia).
Symptoms include itching at night, a pimply rash, sores, and crusty patches.
The human itch mite (Sarcoptes scabiei var. hominis) is a microscopic bug that is one of the few to actually burrow and live beneath human skin. Adult female itch mites burrow under the top layer of skin, where they can continue to live and lay eggs for weeks undetected.
Tapeworm cysts sometimes rupture, releasing more larvae, which can move to other organs and form additional cysts. A ruptured or leaking cyst can cause an allergy-like reaction, with itching, hives, swelling and difficulty breathing.
What do intestinal worms look like? Intestinal worms that infect humans and their larvae vary in appearance and size: threadworms — these worms are like tiny white moving threads 2-13 mm long; they are visible to the naked eye. Strongyloides — the larvae are microscopic in size, but mature into 2-3 mm long worms.
The group of insects called the burrowing webworms includes several species of caterpillars occasionally found in home lawns and commercial turfgrass. These unusual insects are interesting and cause very little damage to turfgrass. One species that is easy to notice is called the cigarette paper webworm.
Filariasis is a parasitic infection with a type of roundworm. Tiny worms, too small to see with the naked eye, invade your body. Under a microscope, the filarial worms look like threads.
Scabies is a skin condition caused by the Sarcoptes scabiei var hominis mite. These little bugs make tunnels (burrow) under your skin and cause small red bumps and severe itching. Scabies spreads easily from person to person, especially among people who live close together.
Humans become infected when blackflies deposit Onchocerca infective larvae into the skin when biting to extract blood. Once inside the human body, the larvae mature into adults in approximately 12–18 months. Most adult female worms live in fibrous nodules under the skin and sometimes near muscles and joints.
Some gardeners use household items like coffee grounds and garlic powder to keep burrowing rodents at bay. Just sprinkle them around active tunnels in your lawn and garden to deter pests from sticking around. You can find a number of commercial products designed to keep burrowing animals away as well.
The larvae in the contaminated soil or sand will burrow into the skin and cause the skin to become irritated in that area. For example, this can happen if a child is walking barefoot or playing in an area where dogs or cats have been (especially puppies or kittens).
The larvae mature into a form that can penetrate the skin of humans. Hookworm infection is mainly acquired by walking barefoot on contaminated soil.
find a large worm or large piece of worm in your poo. have a red, itchy worm-shaped rash on your skin. have sickness, diarrhoea or a stomach ache for longer than 2 weeks. are losing weight for no reason.
Threadworms live about 5-6 weeks in the gut, and then die. However, before they die the female worms lay tiny eggs around the anus. This tends to be at night when you are warm and still in bed. The eggs are too small to see, but cause an itch around the anus.
Cysticercosis can have considerable impacts to human health. The pork tapeworm larvae may develop in the muscles, skin, eyes and the central nervous system. When cysts develop in the brain, the condition is referred to as neurocysticercosis.
If your doctor confirms you have a tapeworm infection, follow their instructions to lessen the risk of complications. If left untreated, there's the risk of developing an invasive infection which can affect your tissue and organs. This can lead to brain swelling, inflammation, and intestinal blockage.

Various cestode or tapeworm species, such as Taenia solium, Echinococcus granulosus, and Spirometra spp., may form cysts under the skin.
A wide range of parasitic infections can present as superficial nodule. Various parasites pass through the skin on its migration to the blood stream or the infestation may be localised to the skin and subcutaneous tissue.
The blackhead worm is a large earthworm. It is dark greyish brown in colour with a distinctive black head. Blackhead worms are deep burrowers. Their burrows can extend as deep as 3 metres. They look for food on the soil surface and then drag it down into their burrows.
Itching and a localized rash are often the first signs of infection. These symptoms occur when the larvae penetrate the skin. A person with a light infection may have no symptoms. A person with a heavy infection may experience abdominal pain, diarrhea, loss of appetite, weight loss, fatigue and anemia.
