Causes

HFMD is caused by an enterovirus. It spreads easily from person to person through contact with an infected person's:

• Mucus
• Sputum
• Fluid from blisters
• Stool

Risk Factors

This problem is more common in children under 10 years of age. Contact with an infected person raises the risk of infection.

Symptoms

Problems may be:

• Fever
• Eating or drinking less than usual
• Sore throat
• Painful sores in the mouth
• Drooling
• A skin rash on the palms of the hands and soles of the feet

Diagnosis

The doctor will ask about your symptoms and health history. A physical exam will be done. This is often enough to make the diagnosis.

If the diagnosis is not clear, a throat swab or stool sample may be taken to find the virus causing the infection.

Treatment

Most people get better on their own in 7 to 10 days. The goal is to manage symptoms and promote healing. Choices are:

• Over the counter pain relievers
• Drinking plenty of fluids

Prevention

The risk of viral infection may be lowered by:

• Practicing proper handwashing
• Covering the mouth and nose when coughing or sneezing
• Not touching the eyes, nose, and mouth
• Avoiding close contact with people who are infected
