Scabies

Name
Scabies

Also known as
Scabs

Caused by
Sarcoptes scabiei

Type
Parasitic

Incidence
An estimated 1 million new cases a year in the United States.

Symptoms
Red, intensely itchy rash in infected areas (which can be almost anywhere on the body). It may also be possible to see small bumps resembling pimples.

Incubation
Infection is immediate and can sometimes occur through non-sexual means such as sharing towels or sleeping in the bed of an infected person. After infection, the mites tunnel beneath the skin to lay eggs. After the eggs hatch, the baby mites tunnel to the surface starting the whole process anew. Symptomes are usually felt within two to six weeks, or in a matter of days in cases of reinfection.

Diagnosis
Microscopic inspection of the skin.

Complications
Uncommon. In certain parts of the world, however, the mites can carry various forms of disease.

Treatment
Prescription or over-the-counter cream, lotion, or shampoo (e.g. Kwell, RID, Nix). All clothes, bedsheets, combs and other personal articles must be washed or treated since lice can live for over 24 hours once they leave the body.
