What is Hand, foot, and mouth disease?

Hand, foot, and mouth disease (HFMD) is caused by viruses. It is often found in infants and children younger than 5 years old. However, this disease can also be found in older children and adults. Typical symptoms are fever, mouth sores, blisters inside the mouth, and skin rash.

Hand, foot, and mouth disease is caused by viruses that belong to the Enterovirus family. Most of them are Coxsackievirus A16, Coxsackievirus A6, and Enterovirus 71. During the first week of exposure is usually the most contagious period. The highest prevalence is during the rainy season (May-October).
 
 

What are the symptoms?

The initial symptoms of the disease are as follows:

• Fever
• Reduced appetite

One or two days after the fever starts, the pain will begin in the mouth. There are small red spots, often in the back of the mouth, that blister can become painful. It causes pain rash on the palms and soles of the feet, which will gradually increase. It may have a flat rash, red spots or blisters. Occasionally it may also spread to the knees, elbows, buttocks and genital area.
In young children, dehydration may occur. If they are unable to eat or swallow enough liquids due to sores in the mouth, you should consult a doctor immediately to treat all symptoms.
All of the above symptoms can be found in most children. In the event of viral infection in adults may have only a few symptoms or show no symptoms at all. And only a small portion of the symptoms are severe. However, the virus can also spread to others.
