What is a Scabies Rash?
A scabies rash is an itchy infection of the skin caused by the microscopic parasite called Sarcoptes scabiei. The parasitic mite tunnels through the surface of the skin and nestles itself into the underlying layers of its victim, causing irritation and setting off an allergic reaction. Scabies is also known as the seven-year itch and the disease can be transmitted through prolonged direct skin-to-skin contact with an infected person.
Scabies Rash Symptoms
Scabies is primarily identified through the main symptoms of severe itching and the development of a skin rash. The itching is notably worse at night and worse when the temperature of the skin is warmer. The scabies rash has the following characteristics:
- Red and raised
- Rashes are usually found next to small lines on the skin which is the trail left behind by the parasite
- Scratching results in open sores that eventually crust over
- Most commonly appear on the hands, feet, back, and buttocks
- Can appear on the external genitalia if the contracted through sexual transmission
Scabies Rash Causes
The causative agent of the scabies rash is the Sarcoptes scabiei mite. A scabies infestation begins when a female is able to burrow underneath the skin and then lays up to 25 eggs. The presence of these parasites initiates an immune response that results in the symptoms of allergy and infection.
Scabies Rash Treatment
Prescription topical drugs such as lindane or permethrin are applied onto the skin after properly bathing and cleansing the body, and then left on the skin overnight. Any articles of clothing or linen used by an infected person should also be thoroughly washed and dried under heat to eliminate any lingering mites. Others who live in the same home with an infected person can also undergo treatment to ensure that transmission is avoided.
