Boils
|
Most often
caused by the Staphylococcus bacterium, a boil takes hold in a
hair follicle and prompts the formation of a red lump, which
gradually fills with yellow pus as the infection thrives. The
lump can become painful from pressure on nerves.
Boils often
arise in crops because of the high local concentration of
bacteria. If other follicles become infected, a carbuncle, which
is a multi-headed boil, can form; It can grow as wide as 5 cm (2
in) across.
|
Key sites for
boils are the back of the neck, armpit and groin, where
Staphylococci colonize because these areas offer an attractive
moist environment for the organism to thrive; Boils sometimes
develop at other sites such as in the nose.
A
stye
is a small boil in an eyelash follicle.
|
To reduce the
chance of infection spreading, thoroughly wash the area around a
boil with an antiseptic soap. In severe cases, antibiotics can
prevent further development but, once a boil has become
established, it must run its course and cannot be eliminated
without treating with drugs.
Do not burst
a boil because this can spread infection. Applying a hot
compress can relieve discomfort and soften the boil, allowing it
to come to a head.
For a large
boil, a visit to a doctor may be necessary to lance it under a
local anesthetic.
|
Poor personal
hygiene,
obesity and heavy sweating encourage boils. People with
diabetes and
eczema can also be prone to boils because they have lowered
resistance to bacterial infection.
|
Impetigo
|
Contagious
weepy blisters that burst, leaving behind honey-colored crusts
or scabs can identify impetigo, which is caused by
Staphylococcus or Streptococcus bacteria.
|
It often
starts around the lips, nose and ears, especially, if there are
cuts, scratches, cold sores or eczema. Touching the affected
skin can spread the infection around the body and to others
|
Antibiotic
tablets clear infection in about 5 days. Loose crusts should be
gently washed off with soap and water and dabbed dry.
|
Keep affected
children away from school and prevent them from touching others.
Boil pillowcases, towels and flannels after every use.
|
Warts
|
Common,
contagious, but mostly harmless growths on the skin,
warts are caused by infection by the human papilloma virus (HPV).
At least 30 types of HPV have been identified.
Children are
susceptible to human papilloma virus because their immunity is
less developed. Ill health in older people also makes them
susceptible.
|
Common warts
appear on sites prone to injury such as hands, face, elbows and
knees, especially in children.
Plantar
warts, or verrucas, on the sole of the foot can be painful when
standing.
Flat warts
occur mainly on the wrists, hands and face.
Genital warts
are spread by sexual intercourse.
|
About 50
percent of warts disappear of their own accord within a year.
However, wart paints or gels, available over the counter from
pharmacies, are quick and effective. Most contain salicylic acid
and should be used after a bath when the skin is soft and
absorbent.
Warts can be
frozen off with liquid nitrogen—this is called cryotherapy.
|
If you have a
verruca, cover it in swimming pools and public showers to avoid
spreading it.
You should
always report genital warts to your doctor. They greatly
increase the risk of
cervical cancer in women and can be spread between sexual
partners. Use a condom during sexual intercourse.
|
Molluscum
contagiosum
|
This highly
contagious viral infection mainly affects children—particularly
those with eczema. It forms shiny wart-like spots, or papules,
which develop a dimple on the top as they grow.
|
The papules
usually appear in groups on the genitals, thighs, face and
elsewhere and can be spread around the body by scratching.
|
They
sometimes disappear on their own. Treatments include freezing
with liquid nitrogen or liquid phenol. The doctor may prescribe
an ointment that can limit the spread. Children with only a few
warts can soak in a warm bath, and then gently scrub with a
pumice stone.
|
Prevent an
infected child from sharing baths and towels with others.
|
|
|
Ringworm
|
Red, itchy
scaly patches with centers that usually heal and leave
characteristic scaly circles are the symptoms of ringworm, a
type of fungal infection.
It can cause
persistent scaling that resembles eczema on the
hands and feet. If the scalp is infected, it can cause
patchy hair loss.
|
Patches are
most often on the torso, groin (known as jock itch). Buttocks
and armpits.
Ringworm can
occur on the palms of the hands and the soles of the feet, as
well as on the scalp.
It can also
infect nails, giving them a smooth white or crumbly yellow
surface.
|
Treat early
with antifungal creams, tablets or nail paints. Most infections
clear in a week or two, but continue treatment as prescribed to
prevent regrowth.
Nails take a
year to heal. In persistent cases, skin or nail samples may be
sent to a laboratory for analysis.
|
To protect
others, use separate towels and flannels. Unaffected people in
the household may minimize the risk of infection by using an
antifungal dusting powder.
|
Athlete’s foot
|
The skin
becomes cracked and sore and often
blisters and peels away when infected by
athlete’s foot, a type of fungal infection. Affected nails
become detached or thick and discolored. It often occurs in
those who wear thick boots or shoes.
|
It is common
between the toes, from where it can spread to soles of the feet
and the toenails.
|
Antifungal
cream can clear up this condition.
|
Dry your feet
carefully, and dust them with antifungal powder. Always wear
cotton socks and change them daily. Wear sandals or go bare foot
it possible. Disinfection bathroom and shower floors help
prevent the infection from spreading.
|
Pityriasis
versicolor
|
In this
condition, while, brown or salmon scaly patches up to 1 cm (½
in) wide are caused by a fungus that is normally present on the
skin, but growing at an abnormal rate. It most often affects
young and middle aged adults, especially men.
|
The patches
typically appear on the torso and arms, with no other symptoms.
|
Carefully
treat the whole body with an antifungal shampoo. If any patches
are missed, the fungus will recur: The skin may take several
moths to return to its normal shade.
|
Not
contagious, but people who are prone to the condition should
change their underclothes and nightwear daily and thoroughly
wash them.
|
Scabies
|
Caused by a
parasite called Sarcoptes scabei, scabies is transmitted from
person to person by close contact, such as sharing a bed,
hugging or sitting on a knee. Eggs show up as tiny grey scaly
swellings. There is inching or; later, reddish lumps, caused by
an immune system reaction to protein produced by the mites.
|
Female mites
lay eggs just under the skin’s surface, most often on the
fingers and wrists, around the nipples in women. The eggs may
not hatch for a moth, but when they do, the inching becomes
severe and affects the whole body from the neck down.
|
Use special
“scabicide” preparations over the entire body, particularly in
any skin crevices. The itching may persist for up to two weeks.
|
Scabies is
highly contagious during the “Window” period between infection
and when the eggs hatch. Treat anyone who has been in physical
contact with an affected person at the same time, whether or not
itching is present, Wash bed linen and underwear; Hang out other
clothes or store in bag for 24 hours—the mites die quickly once
they are away from the body.
|
Lice
|
These small
insects feed on blood and cause irritation by puncturing the
skin. There are three types: head lice (nits) and pubic lice
(crabs), which live on body hairs, and body lice. All of them
cause intense itching.
|
Head lice
live on the scalp, are common in children and spread by close
contact.
Easy-to-see
pubic lice infest pubic hair and are often spread by sexual
contact.
The rare body
lice feed on skin but live and lay eggs in unclean clothing.
|
For head or
public lice, apply a special lice shampoo, and use a fine
toothed comb to remove the eggs from hair.
Boil or dry
clean clothes to kill body lice.
|
Ensure lice
are gone by repeating treatment weekly for several weeks, and
check and treat those who are in close contact with an affected
person.
To avoid
pubic lice, do not share towels or clothes used by an affected
person.
