Impetigo vs. Hand, Foot, and Mouth Disease: How to Tell the Difference
Impetigo and hand, foot, and mouth disease (HFMD) are both common childhood infections that cause skin rashes. However, they are caused by different viruses and present with distinct symptoms. Knowing the key differences can help parents and caregivers seek appropriate treatment and prevent the spread of these contagious illnesses. This article will help you differentiate between the two conditions, addressing common questions parents often have.
What is Impetigo?
Impetigo is a highly contagious bacterial skin infection, most often caused by Staphylococcus aureus or Streptococcus pyogenes. It typically appears as honey-colored crusts or blisters on the face, particularly around the nose and mouth, but can spread to other areas of the body. The sores are usually itchy and can be painful. Impetigo is easily spread through direct contact with infected skin or through shared items like towels or toys. While it's more common in children, anyone can contract impetigo.
What is Hand, Foot, and Mouth Disease (HFMD)?
HFMD is a viral infection, most commonly caused by coxsackieviruses A16 and enteroviruses 71. It’s characterized by a fever, followed by a rash of small, painful sores or ulcers inside the mouth, and on the hands and feet. These sores are often accompanied by a blister-like rash on the palms of the hands and soles of the feet. The rash can also appear on the buttocks. HFMD is highly contagious, primarily spreading through respiratory droplets (coughing and sneezing) and direct contact with stool (fecal-oral route).
What are the key differences between impetigo and hand, foot, and mouth disease?
| Feature | Impetigo | Hand, Foot, and Mouth Disease (HFMD) |
|---|---|---|
| Cause | Bacterial infection (Staphylococcus aureus or Streptococcus pyogenes) | Viral infection (Coxsackievirus A16 or Enterovirus 71) |
| Location | Primarily face (around nose and mouth), can spread elsewhere | Mouth, hands, feet, and sometimes buttocks |
| Appearance | Honey-colored crusts or blisters | Small, painful sores or ulcers, blister-like rash |
| Fever | Usually absent | Often present |
| Treatment | Topical or oral antibiotics | Supportive care (rest, fluids, pain relief) |
| Contagiousness | Highly contagious | Highly contagious |
How is impetigo treated?
Treatment for impetigo typically involves topical or oral antibiotics prescribed by a doctor. Good hygiene, such as frequent handwashing and keeping the affected area clean, is crucial to prevent the spread of the infection. In severe cases, hospitalization might be necessary.
How is hand, foot, and mouth disease treated?
There is no specific treatment for HFMD. Treatment focuses on managing symptoms, including fever reduction, pain relief, and ensuring adequate hydration. Rest is vital to allow the body to fight off the infection. Most cases resolve within 7-10 days.
How long is each condition contagious?
Both impetigo and HFMD are contagious. Impetigo is typically contagious until the lesions have crusted over and are no longer weeping. HFMD remains contagious for as long as the blisters and sores are present and sometimes even after they have healed. Good hygiene practices are critical to prevent spreading either condition.
When should I seek medical attention?
You should consult a doctor if you suspect your child has either impetigo or HFMD. A healthcare professional can properly diagnose the condition and provide appropriate treatment. Seek immediate medical attention if the child develops signs of severe dehydration, high fever, lethargy, or difficulty breathing.
