Impetigo
Impetigo is a highly contagious bacterial skin infection that commonly affects children. It is caused by the bacteria Staphylococcus aureus or Streptococcus pyogenes. Symptoms include red sores or blisters on the skin, which eventually burst and become crusted. It is spread by direct contact with an infected person or objects they have come into contact with. Treatment involves antibiotics, which may be given orally or applied topically. Good hygiene and keeping wounds clean and covered can help to prevent the spread of impetigo. Children with impetigo should avoid close contact with others until the sores have healed completely. In rare cases, impetigo can lead to complications such as cellulitis or kidney problems. Immediate medical attention should be sought in such cases.
Symptoms of Impetigo
What are the common symptoms of impetigo?
Common symptoms of impetigo include red sores that quickly turn into blisters filled with pus, which eventually burst and form a yellowish-brown crust. These sores can be itchy and may also cause some degree of pain. In some cases, there may be swollen lymph nodes and fever.
How is impetigo typically caused?
Impetigo is typically caused by bacteria, primarily Streptococcus pyogenes and Staphylococcus aureus. These bacteria can be easily spread through contact with an infected individual or objects contaminated with the bacteria.
Can impetigo be caused by bacteria or virus?
Impetigo is caused by bacteria, not a virus.
Are there any risk factors that can contribute to impetigo?
Risk factors for impetigo include having a weakened immune system, poor hygiene, living in crowded conditions, and participating in contact sports.
What are the potential long-term effects of impetigo if left untreated?
If left untreated, impetigo can lead to complications such as cellulitis, meningitis, and sepsis. It is also possible for the infection to spread to other areas of the body through scratching or touching the affected areas. In severe cases, scarring may occur.
Diagnosis of Impetigo
What are the typical visual symptoms of impetigo?
The typical visual symptoms of impetigo include red sores that can break open, ooze fluid, and form honey-colored crusts. The sores may be itchy or painful and commonly appear on the face, hands, and feet. It can also spread to other parts of the body.
Is a bacterial swab test the most common form of impetigo diagnosis?
A bacterial swab test is one of the most common forms of impetigo diagnosis. The healthcare provider will take a sample of the fluid or pus from the sore and send it to a laboratory to be tested to identify the exact type of bacteria causing the infection. This test helps to determine the most effective treatment plan for the patient.
Can a healthcare provider confidently diagnose impetigo based solely on physical examination?
Healthcare providers can diagnose impetigo confidently based on physical examination. They will examine the appearance of the sores and ask about symptoms such as itching or pain. However, in some cases, a bacterial swab test may be necessary to confirm the diagnosis.
How long does it take to receive impetigo test results?
The length of time it takes to receive impetigo test results can vary depending on the laboratory that is conducting the test. Most labs can provide results within a few days, but some may take longer. Healthcare providers can provide an estimation of when the results will be available.
Are there any additional tests or exams that may be necessary for an impetigo diagnosis?
In most cases, a bacterial swab test is sufficient for an impetigo diagnosis. However, if the infection is severe or if the patient has a weakened immune system, additional tests or exams may be necessary. This may include blood tests, urine tests, or imaging tests to rule out other conditions or to monitor the progression of the infection. A dermatologist or infectious disease specialist may also be consulted for a more thorough evaluation.
Treatments of Impetigo
What is the recommended course of antibiotics for impetigo?
Recommended course of antibiotics for impetigo usually involves topical antibiotics such as retapamulin, mupirocin, or fusidic acid creams/ointments. In addition, oral antibiotics such as dicloxacillin, cephalexin, erythromycin, and clarithromycin may be prescribed for more severe cases or when the infection has spread throughout the body.
How often should impetigo lesions be cleaned and covered?

Can impetigo be treated with over-the-counter topical creams?
Impetigo lesions should be cleaned with soap and water and covered with a sterile bandage or gauze to prevent spreading of the infection. The cleaning and covering should be done several times a day until the lesions have completely healed.
Is hospitalization required for severe cases of impetigo?

What are some common home remedies for managing impetigo symptoms?
Over-the-counter topical creams are not recommended for the treatment of impetigo. It is important to seek medical attention and follow the prescribed treatment plan to effectively manage the infection.
Prognosis of Impetigo
What is the prognosis for untreated impetigo?
The prognosis for untreated impetigo is highly variable and can depend on various factors such as the severity of the infection, age, and overall health of the patient. In general, untreated impetigo can lead to long-lasting and widespread outbreaks of the infection, and serious complications such as sepsis or kidney damage can occur in rare cases.

Can impetigo lead to more serious health complications?
With proper treatment, impetigo can usually clear up within 7-10 days, but this can vary depending on the extent and severity of the infection. Treatment typically involves a course of antibiotics, which may be prescribed in the form of topical ointments, oral medications, or a combination of both.

How does the prognosis of impetigo differ between adults and children?
While impetigo itself is not typically considered a serious health threat, it can lead to more serious complications in some cases. For example, untreated impetigo can spread to other parts of the body and cause more extensive outbreaks of the infection. It can also lead to scarring or disfiguration of the skin if left untreated. In rare cases, impetigo can lead to serious complications such as sepsis or kidney damage.
Prevention of Impetigo
What are some preventative steps for Impetigo?
Some preventative steps for Impetigo include maintaining good hygiene, avoiding close contact with infected individuals, keeping open wounds covered, and avoiding sharing personal items such as towels, clothing or combs. In addition, cleaning and disinfecting surfaces can help prevent the spread of the disease. (Source: Mayo Clinic)
How important is good hygiene in preventing Impetigo?
Good hygiene is crucial in preventing Impetigo. Washing hands regularly, showering, and keeping the affected areas clean can help prevent the spread of the disease. Additionally, avoiding sharing personal items can also prevent the spread of the bacteria that cause Impetigo. (Source: Centers for Disease Control and Prevention)
Can covering skin abrasions help prevent Impetigo?
Covering skin abrasions can help prevent Impetigo. An open wound is susceptible to infection, and covering it may prevent bacteria from entering the wound and causing Impetigo. If the wound is already infected, covering it can also help prevent the spread of the disease. (Source: American Academy of Dermatology)
Is avoiding contact with infected individuals a key prevention strategy for Impetigo?
Avoiding contact with infected individuals is a key prevention strategy for Impetigo. Impetigo is highly contagious, and coming into contact with someone who has it can put one at risk of contracting the disease. Therefore, avoiding close contact with infected individuals can reduce the risk of infection. (Source: World Health Organization)
Are there any vaccines or medications available for preventing Impetigo?
There are no vaccines currently available for preventing Impetigo. However, antibiotics may be prescribed to treat the disease and prevent its spread to others. It is important to consult a healthcare professional for a proper diagnosis and treatment plan. (Source: American Academy of Dermatology)
