Officials with the University of North Florida Student Health Services reported 13 students required treatment for infestation or exposure to scabies, according to the school newspaper, UNF Spinnaker.
Scabies is caused by an infestation by the eight-legged “itch mite”, Sarcoptes scabiei. The mites burrow into the skin and lay eggs.
These burrows are tiny threadlike projections, ranging from 2 mm-15 mm long that appear as thin gray, brown, or red lines in affected areas. The burrows can be very difficult to see.
Transfer of this mite from person to person typically occurs through prolonged direct contact with infested skin. Transfer from undergarments and bedclothes occur only if these have been contaminated by an infested person immediately beforehand.
Outbreaks have happened in nursing homes and similar institutions, albeit rare.
It may take up to two months for symptoms to appear after initial infestation. Scabies produces skin rash composed of small red bumps and blisters and affects specific areas of the body.
Lesions are prominent around finger webs, wrist and elbows, armpits, belt line, thighs and genitalia of males and nipples, abdomen and buttocks are frequently affected in women. In infants; the head, neck palms and soles may be involved.
Itching is intense, especially at night and complications due to secondary bacterial infections with staph and strep are possible.
The Centers for Disease Control and Prevention recommend the following to prevent and control scabies:
Scabies is prevented by avoiding direct skin-to-skin contact with an infested person or with items such as clothing or bedding used by an infested person. Scabies treatment usually is recommended for members of the same household, particularly for those who have had prolonged skin-to-skin contact. All household members and other potentially exposed persons should be treated at the same time as the infested person to prevent possible reexposure and reinfestation.
Bedding and clothing worn or used next to the skin anytime during the 3 days before treatment should be machine washed and dried using the hot water and hot dryer cycles or be dry-cleaned. Items that cannot be dry-cleaned or laundered can be disinfested by storing in a closed plastic bag for several days to a week. Scabies mites generally do not survive more than 2 to 3 days away from human skin. Children and adults usually can return to child care, school, or work the day after treatment.
