Sarcoptes Scabiei (Scabies)
• Scabies is an itchy, highly contagious skin
disease caused by an infestation by the itch
mite Sarcoptes Scabiei.
• Direct skin-to-skin contact is the mode of
transmission
• A severe and relentless itch is the
predominant symptom of scabies
• However, It can affect any individual
irrespective of social class, caste, age ,
gender or race

The Scabies Mite

History of Scabies
• Scabies has been seen in humans since ancient time.
Archeological evidence from Egypt and the Middle East
suggests scabies was present as early as 494 BC
• It is suspected that some biblical “leprosy” (Hansen’s
disease) was actually scabies
• Aristotle (384-323 BC) mentioned "lice in the flesh" that
produced vesicles
• Greek physician Celsus is credited with naming the
disease "scabies" and describing its characteristic
features.

Some Stats About Scabies
• World wide there are an estimated 300 million cases a
year
• Immunocomprimised people more likely to develop
Norwegian (crusted) scabies.
• 7% of people will develop nodular scabies (nodules
can last for several months)

Life Cycle of the Scabies Mite

Population of Scabies Mites
• Numbers of adult mites
(burrows) build up
slowly
• Symptoms only start
after several weeks
• The number of active
females increases until
• Immune response inhibits
increase
• Scratching eliminates
many burrows

Adult Female Mite (Mother of Scabies)
• Adult female mites form
burrows in the stratum
corneum (dry horny layer of
skin)
• They cut into the cells using
sharp “elbow” joints on the
front pair of legs and secrete
a skin dissolving enzyme
• Usually only have 10 – 15 live
mites on the body
• Obligate parasite (lives its
entire life on the host)

Adult Female Mite (Mother of Scabies)
• Newly matured females form a short burrow and wait for a
male to find them
• Males and females mate in the burrow
• Males then wander off – in search of other females
• They lay eggs, defecate (scybala), and die in the burrow
• The female enlarges the burrow and stays there for the rest
of her life – burrows about 2-5mm per day (nodular scabies
if she goes too deep)?
• Larva makes its way to skin surface
• Female may live for 60 days
• Can lay 150 – 180 eggs
• Can ‘travel’ 10 – 15 cm under the skin

How is Scabies Transmitted
• Direct skin-to-skin contact is the mode of transmission
• They can only live off of a host body for 24-36 hours
under most conditions
• sharing bedclothes that had mites in them the night
before.
• Sexual physical contact,

Signs and Symptoms of Scabies
• Can be up to 6 – 8 weeks before first symptoms develop:
• Unfortunately, these signs are often overlooked, long
term can result in eczema and dry areas
• Infants often develop pustules on hands and feet

Diagnosis of Scabies aka Seven Year Itch
• Scabies is a great masquerader that mimics other skin
problems, e.g. impetigo, vasculitis, insect bites, psoriasis,
all of which complicate diagnosis
• Removing a mite from a burrow with a needle or skin
scraping. Examined under a microscope to confirm the
presence of mites or eggs

Precautions for Treatment of Scabies
• Although mites may only burrow in certain places juveniles may
be found over the whole body
• Wearing gloves and a disposable apron, apply cream or lotion to
cool dry skin to all skin surfaces from head to toe (study):
 including under nail ends – is especially important for
infants and elderly
 awkward places such as the back, soles of the feet, between
fingers and toes, and the genitals.
 Pay special attention to the areas where mite burrows most
commonly occur, the front of the wrists and elbows, beneath
the breasts, the armpits, and around the nipples in women.
• Repeat treatment after 7 days
• If you wash your hands before end of treatment - reapply

N.B. The itch of scabies continues for 2 weeks or more
following treatment. Relieve the itch with Eurax or
calamine.
In severe cases of crusting using an emollient to help
remove crusts will enable treatment to work more
effectively.

Environmental Precautions
• Patients clothing should be placed into soluble bags
• Hoover bags should be discarded after each use into a
plastic bag and tied immediately
• Clothes, towels, and bed linen should be machine washed at
50°C or above after the first application of treatment. This
kills the scabies mites.
• Keep any items of clothing that cannot be washed, in
plastic bags for at least 72 hours to contain the mites until
they die
• Pressing clothes with a warm iron, dry cleaning, or putting
items in a dryer on the hot cycle for 10–30 minutes is also
effective

Norwegian (Crusted Scabies)
• Highly contagious due to the large number of parasites
embedded in the crusts possibly close to 1 million mites!
• Crusted scabies is more easily transmitted through contact
with towels, bedding and upholstery

Points to take Care
• Notify the Health Protection Unit (HPU) of outbreak (two
or more residents affected)
• Do liaise with the local infection control team or HPU for
support and advice
• temporarily close to admissions / respite patients until
completion of the first
• Follow the outbreak care
• All GPs should be informed of the problem
• Staff who have had one treatment can return to work
