Lice, Scabies, and Molluscum
Lice
Lice are parasites--tiny insects that infest the hairy part of the body and feed on human blood.
Pubic lice, which are found in pubic hair, are very tiny lice, often called "crabs" because they look like crabs when examined under a magnifying glass.
Symptoms
Lice will cause persistent itching in the genital or rectal area.
You may see nits, which are small white egg cases, attached to the base
of the hair, or you may notice small brownish-colored lice attached to the hair shaft.
Lice are spread through direct contact with an infected person and direct
contact with personal items belonging to an infected person. Using someone
else's clothing, hats, bedding, and towels should be avoided. It is possible
to become infected with lice by using a contaminated toilet seat.
Treatment
- Apply Kwell Shampoo to the infected area, making sure the hair is
entirely wet. Allow the shampoo to remain on for four minutes.
- With a very fine comb (usually provided when you purchase the shampoo),
remove dead lice and nits.
- Wash all clothing, bed linens and towels in hot water, and machine
dry on the hot temperature setting.
- Disinfect non-washables such as bedding, furniture, and rug with RTC
Spray, which can be purchased at most pharmacies.
- Warn your sexual partner and people living with you that they too
may be infected and need to be treated.
Scabies
Scabies is a skin disease caused by a tiny organism known as the
"itch mite." It causes a red, itchy rash and the itch is most intense at night.
Highly contagious, scabies often spread rapidly among school children,
family members, roommates and sexual partners.
Usually scabies are spread by direct contact with another infested person.
Symptoms
Scabies mites mate on the skin's surface, then the female burrows
into the skin to lay her eggs, causing the skin to itch. The temptation
is to scratch, but this can invite greater infection. Because scabies are
1/60 of an inch or smaller, they are difficult to see. A grayish-white thread
on the skin may mark a female's burrow. A clinician will look for this symptom
between fingers, on the backs of hands, elbows, armpits, breasts, groin,
penis, along the belt line, on the back, or buttocks. Symptoms may take
4-6 weeks to emerge after contact with scabies. The itchy rash typical of
scabies is common to other types of skin disorders, too. Your clinician
will want to confirm your diagnosis by scraping the skin and examining the
scraping under a microscope. This examination is usually quick and painless.
Treatment
Your clinician can prescribe a number of medicines which are effective
against scabies. A cream or ointment may kill the mites within 12 hours,
but the itching may continue 2-3 weeks. Ointments can be purchased that
will soothe the itching.
Prevention
Anyone can get scabies if they come into contact with an infested
person. If a person is reinfested, symptoms may appear more rapidly than
before. If you have a rash, don't assume it is scabies. Come to the University
Health Center for proper diagnosis and treatment.
To prevent scabies infestation:
- Wash your hands often and your hair frequently.
- Wear clean clothes every day and don't exchange clothes with others.
- If anyone in your family is infested, make sure everyone in the family
is checked immediately.
- Don't use the same bedding as an infected person. Someone being treated
for scabies should wear clean clothes and use clean bedding.
- If you have a skin condition that itches mostly at night, get medical
attention as soon as possible.
Molluscum Contagiosum
Molluscum contagiosum, a skin disease caused by a poxvirus, appears
on the skin in small bumps or lesions. The lesions become more "dimpled"
in appearance as they increase in size. Each lesion contains a thick white
core which harbors the virus.
Molluscum is spread through physical contact with a person who is infected.
Once you have molluscum, it can easily spread to different areas on your
body. At one time molluscum was seen mostly in children, but it is now more
prevalent in young adults (16 to 25). It has been associated increasingly
with sexually transmitted infections (STIs).
Treatment
If you think you have molluscum, see a health professional at
the University Health Center so that an appropriate diagnosis can be made.
To treat molluscum, the infected areas of skin are cleansed, and the
lesions opened to remove the core. The lesions should then heal in about
5 to 10 days. Occasionally molluscum will disappear spontaneously, but
in most cases untreated lesions will enlarge and spread.
