Impetigo

What is Impetigo?

Impetigo is a highly contagious bacterial skin infection that is most common in children. It typically appears as a red, swollen rash with small, fluid-filled blisters that may burst and crust over. The blisters are often itchy and may be accompanied by fever and swelling. It is usually caused by the bacteria Streptococcus or Staphylococcus, and it is spread through direct contact with the infected skin or through shared objects such as towels or toys. Impetigo can be treated with antibiotics, and good hygiene is important to prevent the spread of the infection. If you think you or your child may have impetigo, it is important to see a healthcare provider for a proper diagnosis and treatment.

Symptoms and Signs

There might be several signs of impetigo, among which the following are the most common.

• Red, swollen bumps or blisters on the skin
• Yellow, honey-colored crusts or scabs on the skin
• Itching or burning sensation on the affected area
• Pain or discomfort when the sores are touched or burst
• Fever, swollen lymph nodes, or general feeling of being unwell in severe cases
• The affected area may be swollen or tender
• The bumps or blisters may spread to other areas of the body if left untreated.

Causes of Impetigo

It is a highly contagious bacterial skin infection that is caused by either Staphylococcus aureus or Streptococcus Pyogenes bacteria. It is typically found in people who have compromised immune systems or those who have open wounds or cuts on their skin.

Other factors that can contribute to the development of impetigo include:

1. Poor hygiene: Not washing hands regularly or not keeping cuts and wounds clean can increase the risk of contracting impetigo.
2. Crowded living conditions: It is more common in environments where people are in close proximity to each other, such as in schools or daycare centers.
3. Poor skin health: Dry, flaky, or damaged skin is more susceptible to infections such as impetigo.
4. Climate: Humid or hot weather can increase the risk of impetigo as it creates an ideal environment for bacteria to thrive.
5. Poor nutrition: People who have a diet that is low in nutrients may have a higher risk of developing impetigo due to a compromised immune system.
6. Allergies: People who have allergies or eczema may be more prone to developing impetigo as they have damaged skin which is more susceptible to infections.

Complications

Impetigo, itself is a painful, and inflammatory condition. It becomes more complicated when it leads to further complications. It can cause the following medical conditions, which need treatment on time.

1. Cellulitis: It can lead to cellulitis, a serious bacterial infection that affects the deeper layers of the skin and underlying tissue. It can cause swelling, redness, and pain in the affected area and can lead to serious complications if left untreated.
2. Scarring: It can cause scarring, particularly if it is not treated properly or if the sores are scratched or picked at.
3. Septicemia: In rare cases, impetigo can lead to septicemia, a potentially life-threatening condition in which bacteria enters the bloodstream and spreads throughout the body.
4. Reactive arthritis: Impetigo can sometimes trigger reactive arthritis, a type of joint inflammation that occurs as a result of an infection.
5. Ecthyma: A severe form of impetigo that involves deep skin infections can lead to ecthyma, a condition characterized by painful, ulcerated sores that take longer to heal and can leave scars.
6. Lymphadenitis: Impetigo can also cause lymphadenitis, an infection of the lymph nodes that can lead to swelling and tenderness in the affected area.

When to see a doctor?

It is important to see a doctor if you or your child develops impetigo, especially if:

1. The rash is large or spreading quickly
2. The rash is accompanied by fever or other symptoms
3. The rash is not improving with over-the-counter treatment after a few days
4. You have a weakened immune system, such as from cancer treatment or HIV
5. You are pregnant or have a newborn baby, as impetigo can spread quickly to others in close contact.

Risk Factors of Impetigo

There are some factors that can increase the risk of Impetigo; Common most factors are as follows;

1. Poor hygiene: Impetigo is more likely to occur in individuals who do not practice good hygiene, such as regular hand-washing and bathing.
2. Crowded living conditions: People living in close quarters, such as in dormitories or shelters, are more likely to develop impetigo due to increased exposure to the bacteria that cause the infection.
3. Skin injuries: Impetigo is more likely to occur in individuals who have cuts, scrapes, or other skin injuries that allow the bacteria to enter the skin.
4. Chronic skin conditions: Individuals with chronic skin conditions, such as eczema or dermatitis, may be more prone to developing impetigo.
5. Weak immune system: People with compromised immune systems, such as those undergoing chemotherapy or with HIV/AIDS, are more vulnerable to developing impetigo.
6. Age: It is more common in children, especially those under the age of 5.
7. Climate: It may be more common in warmer, humid climates, as the heat and moisture can promote the growth of bacteria on the skin.

How to prevent Impetigo?

Apart from general hygienic preventive measures, there are some other important factor, which can help prevent Impetigo.

There are several ways to prevent impetigo:

1. Wash your hands frequently: Proper hand hygiene is important to prevent the spread of impetigo. Wash your hands with soap and water, especially after using the bathroom, blowing your nose, or touching infected areas.
2. Avoid sharing personal items: Do not share towels, washcloths, or other personal items with others to prevent the spread of impetigo.
3. Keep cuts and scrapes covered: Keep any cuts or scrapes clean and covered with a bandage to prevent infection.
4. Avoid close contact with infected individuals: If someone in your household has impetigo, try to avoid close contact with them to prevent the spread of the infection.
5. Keep the infected area clean and dry: Use warm water and soap to clean the infected area and make sure it is dry before covering it with a bandage. Avoid scratching or picking at the infected area to prevent further spreading.
6. Use antibiotics as prescribed: If you are prescribed antibiotics for impetigo, make sure to take them as directed by your healthcare provider to ensure the infection is properly treated.

How to prevent the spreading of Impetigo?

As impetigo is a highly contagious disease, it can spread from person to person very rapidly. In order to reduce the risk of spreading Impetigo, the following precautionary measures should be taken as tips;

1. Wash your hands frequently with soap and water, especially after touching any affected areas or objects that may be contaminated with the infection.
2. Avoid sharing towels, washcloths, or other personal hygiene items with others.
3. Keep any affected areas clean and covered with a bandage or dressing until the infection has cleared up.
4. Avoid close contact with others, especially those who have weakened immune systems or are at higher risk for infection.
5. If you have impetigo on your face, avoid touching your face or other areas of your body to prevent the spread of the infection.
6. Disinfect any surfaces or objects that may have come into contact with the infection, such as toys, doorknobs, or countertops.
7. If you are prescribed antibiotics for impetigo, be sure to take the full course as directed by your doctor to ensure the infection is fully treated.

How to Diagnose Impetigo?

The above signs and symptoms can help diagnose the condition. A healthcare provider will typically examine the affected area and look for the characteristic symptoms of the infection, such as blisters or scabs on the skin. They may also take a sample of the infected area and send it to a laboratory for testing to confirm the presence of the bacteria responsible for impetigo. In some cases, the provider may also perform a culture test to identify the specific type of bacteria causing the infection. In addition to these tests, the provider may also ask about the patient’s medical history and any recent skin injuries or exposure to other individuals with impetigo.

Treatment of Impetigo

Impetigo is a skin infection caused by bacteria, typically Staphylococcus aureus or Streptococcus pyogenes. It is usually treated with antibiotics, either orally or topically. Topical antibiotics may be in the form of creams or ointments and are applied directly to the affected area. Oral antibiotics are taken by mouth and are usually recommended for more severe cases or if the infection has spread to multiple areas of the body.

Other treatment options include cleaning and covering the affected area to prevent the spread of the infection and using over-the-counter creams or ointments to soothe the skin. It is important to follow the treatment plan prescribed by a healthcare provider, as well as to practice good hygiene to prevent the spread of the infection to others.

Home remedies and lifestyle can prevent Impetigo

Apart from medicines prescribed by the physician, Impetigo can be treated and prevented to spread by adopting a healthy and hygienic lifestyle. Home remedies can be helpful to get the condition treated. Following are some helpful tips to treat Impetigo at home;
