A rash or blisters that appear on these parts of the body may be the sign of an infectious virus that primarily occurs in children under age 10, yet can also occur in adults.
Hand-foot-mouth disease begins with a sore throat and flu-like symptoms. The most notable symptom, however, is the appearance of small painful blisters around the mouth, and a rash on the arms or legs, along with a fever.
Normally, this condition does not end in complications. People who get this disease tend to recover after a period of between five and ten days, and there is no need for any special treatment. According to the U.S. National Library of Medicine, the following treatments may help alleviate symptoms.
- Medications for treating the pain and lowering the fever, such as acetaminophen or ibuprofen.
- Salt water mouth rinses may help soothe the blisters and ulcers in the throat and mouth (1/2 teaspoon or 6 grams of salt to 1 glass of warm water).
- Drink more liquids than normal, this helps prevent dehydration caused by the fever. Avoid sodas and try to drink cold dairy products.
Hand-foot-mouth disease is transmitted as most viruses are: through infected air droplets that spread through sneezing or coughing, or through contact with the fluid from an infected person’s blisters.
