Overview
3

• Impetigo infection is a common skin infection
  that primarily affects young children, although
  it can also occur in adults. It is caused by
  bacteria, most commonly Staphylococcus aureus
  (staph) and Streptococcus pyogenes (strep).
  Impetigo is extremely contagious and can be
  transmitted easily through direct skin-to-skin
  contact or by sharing personal items like towels
  or clothing.
• The infection typically starts when the bacteria
  enter the skin through a cut, scratch, insect
  bite, or other skin condition. The bacteria then
  multiply and cause inflammation and infection in
  the top layers of the skin, resulting in the
  characteristic sores and blisters associated with
  impetigo.
• Impetigo can present in different forms,
  including non-bullous impetigo, bullous impetigo,
  and ecthyma. Non-bullous impetigo is the most
  common type and is characterized by itchy sores
  that quickly burst, leaving behind a
  honey-colored crust. Bullous impetigo involves
  larger, fluid-filled blisters that eventually
  break open and form crusts. Ecthyma is a more
  severe form of impetigo that can cause painful
  blisters and open sores that may lead to
  scarring.
• Prompt treatment is essential to prevent the
  spread of impetigo and to alleviate symptoms.
  Antibiotics, both topical and oral, are commonly
  prescribed to help clear the infection. In
  addition to treatment, practicing good hygiene
  and taking preventive measures can help reduce
  the risk of impetigo.

Key Highlights

• Impetigo is a prevalent bacterial skin infection
  that primarily impacts young children.
• The infection is caused by bacteria like
  Staphylococcus aureus (staph) and Streptococcus
  genus (strep).
• Impetigo causes sores and blisters on the skin,
  which can be itchy and painful.
• Treatment for impetigo includes antibiotics, both
  topical and oral, to help clear the infection.
• Prevention techniques for impetigo include
  practicing good hygiene, avoiding skin contact,
  and maintaining clean environments.
• Complications of untreated impetigo can include
  the spread of infection to other parts of the
  body and long-term health implications.

Understanding Impetigo

• Impetigo is a bacterial skin infection that
  primarily affects young children, although adults
  can also be affected. There are two primary forms
  of impetigo non-bullous impetigo and bullous
  impetigo. The bacteria
• Staphylococcus aureus is what causes non-bullous
  impetigo, which is the most prevalent type. It
  typically starts with the development of itchy
  sores that quickly burst and form a honey-colored
  crust.
• Bullous impetigo, on the other hand, is less
  common and is characterized by larger
  fluid-filled blisters. Both types of impetigo can
  be treated with antibiotics.

6
Defining Impetigo in Clinical Terms

• Impetigo is a bacterial skin infection that
  affects the outer layers of the skin, known as
  the epidermis. The bacteria Staphylococcus aureus
  and Streptococcus pyogenes are responsible for
  it.
• Bullous impetigo is a specific type of impetigo
  characterized by the formation of large,
  fluid-filled blisters on the skin. These blisters
  are caused by the release of toxins from the
  bacteria.
• Non-bullous impetigo, on the other hand, is the
  more common type and is characterized by the
  formation of itchy sores that quickly burst and
  form a honey-colored crust.
• Both types of impetigo can be contagious and are
  typically treated with antibiotics to clear the
  infection.

7
The Epidemiology of Impetigo

• Impetigo is a common skin infection, especially
  among young children. It is estimated that
  impetigo accounts for about 10 of skin
  conditions in children. This infection is more
  prevalent in warm months when children spend more
  time outdoors and have increased exposure to
  bacteria.
• Impetigo is very contagious and can be easily
  transmitted through direct skin contact or by
  sharing personal items like towels or clothing.
  Close contact with an infected individual, such
  as living in the same household or attending
  daycare, increases the risk of contracting
  impetigo.
• Additionally, certain factors, such as having
  cuts, insect bites, or other skin conditions, can
  also increase the risk of impetigo.

8
Identifying Impetigo Symptoms

• Impetigo is characterized by the presence of
  sores and blisters on the skin. The main symptoms
  of impetigo include
• Itchy sores that may be red or pink in color
• Blisters that can burst and form a yellowish
  crust
• Crusty or oozing sores
• Redness and inflammation around the affected
  areas
• Swollen lymph nodes near the sores
• These symptoms usually develop within a few days
  of the bacteria infecting the skin. Impetigo can
  occur on any part of the body but is mostly found
  around the mouth and nose.

9
Early Signs and Progression

• The early signs of impetigo typically involve the
  development of redness and inflammation on the
  skin. This is followed by the formation of
  blisters, which can be filled with fluid or pus.
  These blisters may burst and form a crust or
  scab.
• If left untreated, impetigo can progress and lead
  to the spread of infection to other areas of the
  body. It is important to seek prompt treatment to
  prevent the infection from worsening and to
  alleviate symptoms. Intervening early can prevent
  complications and speed up the recovery process.

10
Visual Guide to Impetigo Lesions
11

• Impetigo lesions can vary in appearance depending
  on the stage of infection and the type of
  impetigo. Here is a visual guide to help you
  recognize impetigo sores
• Non-bullous impetigo The initial stage is
  characterized by the development of small
  blisters or sores that quickly burst and form a
  crust. The affected areas may be red or pink in
  color and can be itchy. Crusty yellow or golden
  scabs may form as the skin heals, and they
  eventually fade without leaving scars.
• Bullous impetigo The lesions in bullous impetigo
  are larger and filled with fluid. They may appear
  clear or translucent and do not show redness or
  inflammation around the surrounding skin. As the
  blisters break open, crusty sores form, and the
  skin heals without scarring.
• Ecthyma This severe form of impetigo involves
  painful blisters that can turn into ulcers. The
  affected areas may have thick crusts and redness
  near the surrounding skin. Scarring may occur as
  the infection goes deeper into the skin.

12
Causes and Risk Factors

• Impetigo is caused by bacteria,
  specifically Staphylococcus aureus and
  Streptococcus pyogenes. These bacteria can enter
  the skin through cuts, scratches, insect bites,
  or other skin conditions.
• Impetigo is highly contagious and can spread
  through direct skin-to-skin contact or by sharing
  personal items such as towels or clothing.
• Certain risk factors can increase the likelihood
  of developing impetigo, including close contact
  with infected individuals, compromised immune
  system, and underlying skin conditions. It is
  important to take preventive measures to reduce
  the risk of impetigo.

13
Bacterial Culprits Behind Impetigo

• Impetigo is primarily caused by two types of
  bacteria Staphylococcus aureus (staph) and
  Streptococcus pyogenes (strep). These bacteria
  are commonly found on the skin and can enter the
  body through cuts, scratches, insect bites, or
  other skin conditions.
• Staphylococcus aureus is responsible for about
  80 of non-bullous impetigo cases, while
  Streptococcus pyogenes accounts for about 10.
• Both types of bacteria can multiply and cause
  inflammation and infection in the top layers of
  the skin, resulting in impetigo. Prompt treatment
  with antibiotics is essential to clear the
  infection and prevent complications.

14
Who is Most at Risk?

• Certain individuals may be more susceptible to
  impetigo due to various risk factors. The table
  below outlines the groups of people who are most
  at risk
• Risk Factors with Examples
• Young Children Preschoolers and toddlers
• Close contact with infected person Siblings,
  classmates, daycare contacts
• Weakened immune system Individuals with
  HIV/AIDS, diabetes, or cancer
• Skin conditions or infections Eczema,
  dermatitis, insect bites
• Living in crowded or close quarters
  Dormitories, military barracks, sports teams
• Young children, especially those in daycare or
  school settings, are at a higher risk of impetigo
  due to close contact with other children and the
  prevalence of the bacteria in these environments.
• Individuals with weakened immune systems, such as
  those with HIV/AIDS or certain medical
  conditions, may also be more susceptible to
  impetigo. Additionally, skin conditions or
  infections can increase the risk of impetigo.

15
Diagnosis of Impetigo Infection

• To diagnose impetigo infection, a healthcare
  professional, will examine the affected areas of
  the skin. They will look for characteristic signs
  such as sores, blisters, and crusts.
• In some cases, they may also take a sample of the
  fluid from one of the sores to send to a
  laboratory for testing. This can help determine
  the specific bacteria causing the infection and
  guide the choice of appropriate antibiotics.
• A professional diagnosis is important to ensure
  accurate identification and appropriate treatment
  of impetigo.

16
Professional Diagnosis Procedures

• A healthcare professional can diagnose impetigo
  through a visual examination of the skin. They
  will look for characteristic signs such as the
  presence of sores, blisters, and crusts.
• In some cases, they may take a bacterial culture
  by collecting a sample of the fluid or crusted
  material from the affected area. This culture can
  help identify the specific bacteria causing the
  infection and determine the most effective
  antibiotics for treatment.
• Additionally, the healthcare professional may
  inquire about any recent cuts, insect bites, or
  skin conditions that may have contributed to the
  development of impetigo. A professional diagnosis
  is essential to ensure accurate identification
  and appropriate treatment of impetigo.

17
Understanding Your Diagnosis

• If you are diagnosed with impetigo, your
  healthcare provider will discuss the recommended
  treatment options with you. The primary treatment
  for impetigo is antibiotics, either topical or
  oral, depending on the severity of the infection.
• Topical antibiotics, such as mupirocin ointment,
  are applied directly to the affected area, while
  oral antibiotics, such as amoxicillin, may be
  prescribed for more widespread or severe cases.
• It is important to follow your healthcare
  providers instructions and complete the full
  course of antibiotics to ensure effective
  treatment.
• In some cases, individuals with underlying health
  conditions or compromised immune systems may
  require additional medical management to prevent
  complications. Your healthcare provider will
  provide guidance on managing your impetigo and
  any associated health conditions.

18
Comprehensive Treatment Strategies
19

• The comprehensive treatment of impetigo typically
  involves a combination of topical and oral
  antibiotics, along with home care measures. The
  treatment strategies may include
• Topical antibiotic cream or ointment These are
  applied directly to the affected areas to kill
  the bacteria and promote healing. Examples
  include mupirocin ointment.
• Oral antibiotics For more severe cases or
  widespread infections, oral antibiotics may be
  prescribed to help clear the infection from
  within the body. Commonly prescribed oral
  antibiotics include amoxicillin and
  cephalosporins.
• Home remedies and care Good hygiene practices,
  such as cleansing the affected areas with gentle
  soap and warm water, can help prevent the spread
  of infection. Applying warm compresses to the
  sores can provide relief and promote healing.
• It is important to follow the prescribed
  treatment plan and complete the full course of
  antibiotics to ensure effective treatment and
  prevent the recurrence of impetigo.

20
Medications and Topical Treatments

• Medication options for impetigo include both
  topical treatments and oral antibiotics. Topical
  treatments are usually the first line of defense
  for mild cases of impetigo. They include
• Antibiotic ointment Mupirocin ointment is
  commonly prescribed and applied directly to the
  affected areas of the skin. It helps to kill the
  bacteria causing the infection and promote
  healing.
• Topical antibiotics In some cases, a healthcare
  professional may prescribe topical antibiotics,
  such as fusidic acid or retapamulin. These
  medications are applied directly to the skin and
  help to eliminate the bacteria causing the
  impetigo infection.
• If the impetigo infection is more severe or
  widespread, oral antibiotics may be necessary.
  These medications are taken by mouth and help to
  eliminate bacteria from within the body.
• Examples of oral antibiotics commonly used to
  treat impetigo include amoxicillin, cephalexin,
  and clindamycin. In cases where
  methicillin-resistant Staphylococcus aureus
  (MRSA) is suspected, alternative antibiotics such
  as trimethoprim-sulfamethoxazole or clindamycin
  may be prescribed.

21
Home Remedies and Care

• In addition to prescribed medications, there are
  several home remedies and care measures that can
  help alleviate symptoms and promote healing in
  cases of impetigo. These include
• Good hygiene practices Regularly washing the
  affected areas with gentle soap and warm water
  can help remove crusts and prevent the spread of
  infection.
• Hot water compresses Applying warm compresses to
  the sores can help soothe discomfort and promote
  healing.
• Natural remedies Some natural remedies, such as
  tea tree oil or diluted apple cider vinegar, may
  have antibacterial properties and can be applied
  topically to the affected areas. Before using any
  natural remedies, it is crucial to consult with a
  healthcare professional to verify their safety
  and effectiveness.
• It is important to note that while home remedies
  and care measures can provide relief, they should
  not replace prescribed medications or medical
  treatment for impetigo.
