Parasitic skin infections
What Are Parasitic Skin Infections?
Parasitic skin infections occur when parasites invade and feed on the skin. Some of the most common types of these infections come from mites, fleas, lice, and ticks. Parasitic skin infections generally cause symptoms such as intense itching, rashes, and skin inflammation, and may result in further skin infections due to excessive scratching.
Types of Parasitic Skin Infections
The most common types of parasitic skin infections include:
- Scabies: caused by the mite Sarcoptes scabiei, scabies causes intense itching and a rash. The mites burrow into the skin, often leading to skin breakdown and secondary infections.
- Lice: two species of lice, Pediculus humanus capitis and Pediculus humanus corporis, can cause parasitic skin infections. These parasites generally cause intense itching and red bumps on the skin.
- Tungiasis: caused by a flea species known as the Tunga penetrans, tungiasis is characterized by a rash, swelling, and intense itching. These fleas generally burrow beneath the surface of the skin and feed on blood.
- Cutaneous larva migrans: this type of infection is caused by the larvae of various parasitic worms. It is characterized by an intensely itchy rash and may be accompanied by swelling and infection.
Treating Parasitic Skin Infections
The treatment for parasitic skin infections depends on the type of infection. In general, it is important to consult a healthcare provider as soon as possible, as these infections can be difficult to self-diagnose and may require medical intervention. In addition, it is important to wash bedding, clothing, and towels in hot water to help eliminate any parasites that may have contaminated them.
Antiparasitic medications are generally used to treat parasitic skin infections. These medications include creams, shampoos, sprays, and oral medications. In some cases, medications used to treat other skin conditions, such as hydrocortisone or antihistamines, may help reduce itching and other symptoms.
