1. What Is Migratory Larva Disease?

Cutaneous larva migrans disease is a form of hookworm infection of the Ancylostoma genus. This type of bacteria exists in dog feces, cat feces or in moist soil. They penetrate the body and parasitize under the skin through unprotected direct contact of human skin with the environment containing hookworms. This disease is quite common everywhere in the world but is most common in tropical environments, hot and humid climates.
The disease often causes extremely uncomfortable itching. The disease can go away on its own after a short time. However, because it causes unpleasant symptoms and infection, the disease needs to be treated with special medication as prescribed by a specialist.

2. Causes And Manifestations Of The Disease

Skin larva migratory disease is caused by the following causes and symptoms:

Cause Of The Disease
Hookworms exist and cause disease in the body of dogs and cats following the feces. in the environment and develop into larvae. This larva can survive in the outside environment for quite a long time, from 3-4 weeks. These larvae penetrate human skin through direct, unprotected contact. When the skin comes into contact with dog or cat feces, or moist soil or sand containing hookworm larvae, they will penetrate the skin and parasitize under the skin. They move in the epidermis causing inflammatory reactions under the skin. In very few cases, the larvae penetrate deeply and cause tissue or lung damage.

Symptoms Of Infection
Migratory skin larvae disease often has fairly easy to recognize symptoms. The warts appear in a number of locations such as the feet, buttocks, trunk, arms, genitals, etc. They are red warts with stripes, slight ridges, palpable and easy to see. seen on the skin. The larvae survive and move to form red bumps, which can increase in size to several centimeters per day. The width of the ridge is about 3mm, up to 15-20mm long. They cause swelling, redness, and itching for the patient. There are also bullous, eczematous or closed lesions with secondary infection.

The disease causes damage under the hair follicles, causing intense itching. If left untreated, signs of the disease can last for several years. They cause lesions and nodules that are very unsightly and affect the patient's health and quality of life.

3. Is Migratory Skin Larva Disease Dangerous?

The disease causes symptoms under the skin and causes a lot of itching and discomfort for the patient. Not too common, this is a disease that causes concern for those unfortunate enough to be infected:

People at high risk of being infected with migratory skin larvae.
Migratory skin larvae disease can occur in anyone, regardless of age. different ages and genders. Among them, the groups at high risk of infection are usually:
* People who often walk barefoot and sunbathe on the beach.
* Young children often play in wet areas and sand pits.
* Farmers often come into contact with damp soil and sand.
* People who work in environments that are frequently exposed to sources of infection: plumbers, housekeeping workers, electricians, pet caretakers, etc.

Can The Disease Go Away On Its Own?
Migratory skin larva disease can go away on its own. The reason is because the human body is an intermediary for parasitic larvae and does not cause disease. Parasitism under human skin is a dead end for the larvae and ultimately death. Symptoms of the disease will disappear after 4-8 weeks. A few rare cases cause complications and secondary infections. Although it can heal on its own, if treated early, it will shorten the duration of the disease and reduce symptoms of itching and discomfort.

Some Complications Of The Disease
Migratory skin larva disease is a benign disease but can cause complications such as: infection in the damaged area, hives, and allergies. The most serious is lung complications causing abnormal respiratory symptoms.

How Is The Disease Diagnosed?
The doctor will diagnose the disease based on an investigation of contact history, whether the patient has ever had direct contact with soil, sand, or dog or cat feces that are at risk of containing larvae. Observe skin lesions and make clinical diagnosis. At the same time, conduct tests to determine leukocytosis. Or use Dermoscopy to diagnose images of lesions under the skin, detect structures, empty larval cavities, etc.

Treatment Of Migrating Skin Larvae
Currently, the most popular method of treating migratory skin larvae is to use larvicide such as: Ivermectin, Albendazole for oral use or Thiabendazole 15% ointment for topical application. In addition, in some cases it may be prescribed to use anticonvulsants, antihistamines, anti-inflammatory drugs, and prevent secondary infections.
