Impetigo and hand, foot, and mouth disease (HFMD) are both common childhood infections causing skin rashes, but they're distinct conditions with different causes, symptoms, and treatments. Understanding their differences is crucial for proper diagnosis and management. This comprehensive guide will help you differentiate between these two conditions, answering common questions many parents have.
What is Impetigo?
Impetigo is a highly contagious bacterial skin infection, primarily affecting infants and young children. It's caused by Staphylococcus aureus or Streptococcus pyogenes bacteria. The infection typically manifests as sores or blisters that break open, forming honey-colored crusts. These lesions are usually itchy and can appear anywhere on the body, but commonly affect the face, around the nose and mouth, and on the extremities.
What is Hand, Foot, and Mouth Disease (HFMD)?
Hand, foot, and mouth disease (HFMD) is a viral infection, most often caused by Coxsackievirus A16 or Enterovirus 71. While it shares some superficial similarities with impetigo in terms of rash location, HFMD presents with distinct characteristics. It's characterized by a fever, followed by a painful rash of small blisters or ulcers inside the mouth (causing difficulty eating and drinking), and on the palms of the hands and soles of the feet. The lesions in HFMD are typically small, flat, and grey-white, surrounded by a red halo.
How Can I Tell Impetigo and HFMD Apart?
The key differences lie in the type of infection, the appearance of the rash, and the accompanying symptoms.
Impetigo:
- Cause: Bacterial infection (Staphylococcus aureus or Streptococcus pyogenes)
- Rash: Honey-colored crusts, often weeping or oozing, can be anywhere on the body.
- Other Symptoms: Generally mild, may include slight fever or discomfort in the affected area. No mouth sores.
- Treatment: Topical or oral antibiotics.
Hand, Foot, and Mouth Disease (HFMD):
- Cause: Viral infection (Coxsackievirus A16 or Enterovirus 71)
- Rash: Small blisters or ulcers inside the mouth, on the palms of the hands, and soles of the feet. Grey-white, surrounded by a red halo.
- Other Symptoms: Fever, sore throat, irritability, and loss of appetite.
- Treatment: Supportive care, including pain relief and hydration. The infection usually resolves on its own within 7-10 days.
What are the Treatment Options for Impetigo?
Impetigo requires treatment with antibiotics to effectively clear the bacterial infection. The doctor may prescribe either topical antibiotics (creams or ointments applied directly to the sores) or oral antibiotics (pills or liquid medications). Careful handwashing and keeping the affected areas clean are also crucial to prevent the spread of the infection.
What are the Treatment Options for Hand, Foot, and Mouth Disease?
There's no specific antiviral treatment for HFMD. Treatment focuses on managing symptoms:
- Pain Relief: Over-the-counter pain relievers like acetaminophen or ibuprofen can help alleviate fever and discomfort.
- Hydration: Encourage frequent fluid intake to prevent dehydration, especially important if the child has mouth sores.
- Soft Foods: Offer soft, bland foods that are easy to swallow to reduce irritation in the mouth.
Is Impetigo Contagious?
Yes, impetigo is highly contagious and spreads through direct contact with the infected sores or contaminated objects. Good hygiene practices, such as thorough handwashing and keeping the sores covered, are essential to prevent its spread.
Is Hand, Foot, and Mouth Disease Contagious?
Yes, HFMD is also highly contagious, spreading through contact with nasal secretions, saliva, stool, and blister fluid from infected individuals. Good hygiene is critical to prevent transmission.
When Should I See a Doctor?
You should consult a doctor if you suspect your child has either impetigo or HFMD. A proper diagnosis is crucial to determine the appropriate treatment. Seek immediate medical attention if your child shows signs of severe dehydration or worsening symptoms.
