Recently hand-foot-mouth disease has spread across China. In the past three months, there have been about 41,846 cases （病例） in 30 provinces and regions. The number is increasing. Eighteen Chinese children have died of the disease so far this year.

    What causes the disease and why is it dangerous?

    Hand-foot-mouth disease is a common childhood illness. It mainly affects children under the age of 10. It gets its name from the rash （疹子） that develops on the hands and feet. It can also cause blisters （水泡） in your mouth.

    A child who has the disease will usually have a fever, a runny nose and sore throat. He or she doesn’t want to eat or drink because of pain in the mouth.

    Hand-foot-mouth disease is mostly not serious. The fever and rash clear within a few days. But in some cases, the virus （病毒） affects the heart, lungs or brain. This puts the child’s life in danger.

    A virus causes hand-foot-mouth disease. The disease spreads easily where a lot of young children are together, such as in a child-care center. Sometimes it can also affect teenagers and adults.

   In order not to pass on the virus, good hygiene （衛生） is important. We should wash our hands as often as possible. Especially we should wash our hands before meals and after going to the toilet.
