Scabies is a common cause of small bump trails on the skin. This mite infestation occurs in folds of the skin, between the fingers, armpits, shoulder blades, knees and soles of the feet, according to MayoClinic.com. People staying at hospitals, nursing homes and child-care centers are at higher risk for developing this infection. Although you can't get scabies form a pet, you can get it from human-to-human contact.
Causes
A microscopic mite causes scabies. The female mite burrows under the skin and deposits eggs. Eggs take 21 days to mature and slowly work their way to the surface of the skin. Your body's reaction to the mites is itching and discomfort. Mite infections spread through human-to-human contact. Sharing personal items also spreads this infestation.
Treatment
Use prescription medications to eliminate scabies infestations. Kill mites by using topical permethin. This medication is safe for children of all ages and pregnant women, according to MayoClinic.com. Use the topical medication twice weekly until the infestation improves. Another option for scabies treatment is the medication crotamiton. This medication is non-chemical and is used in babies.
Lindane is another topical treatment option. Apply this cream twice weekly until the infestation improves. Lindane isn't safe for children younger than 2 or pregnant women.
Considerations
If you have immune system issues, your course of treatment is different. A doctor will prescribe an oral medication, stromectol, to treat a scabies infestation. The oral medication is also used if you are resistant to topical treatments.
Prevention
Prevent reinfestation by cleaning all clothes and linens. Use hot water and soap to wash bedding, clothing, towels and other clothing items used three days before starting treatment, recommends MayoClinic.com. If you can't wash an item, dry clean it. You can also place items in a sealed bag outside for a couple weeks. If the mites can't eat, they will starve. This prevents reinfestation.
Warnings
Avoid scratching small trails of bumps on the skin. Scratching puts you at risk for bacterial infection, such as impetigo. Wearing gloves at night prevents scratching. If you have a weak immune system or are ill, you are at higher risk for developing these secondary infections. Work with your doctor to minimize your risks.
