Recently handfootmouth 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?

Handfootmouth 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.

Handfootmouth 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 handfootmouth disease.The disease spreads easily where a lot of young children are together,such as in a childcare center.Sometimes it can also affect teenagers and adults.

In order not to pass on the virus,good hygiene (衛(wèi)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.

The Internet has become part of teenage life.A new report on 3,375 students aged from 10 to 18 in seven Chinese cities found that 38 percent of them believe they use the Internet often.

While most of them get useful information and use the Internet to help in their studies,some are not using it in a good way.Many are playing online games too much.A few even visit websites they shouldn’t look at.Hong Ying,a teacher from Beijing Yinghua Middle School warns that bad things can happen if young people spend too much time on the Internet.She had a student who used to be good at school.But then he started visiting sex websites.He went mad,cheated a girl and was taken away by the police.

In order to help young people use the Internet in a good way,a textbook on good Internet behavior has started to be used in some Shanghai middle schools this term.The book uses real examples to teach students all about good ways of using the Internet.

The book gives useful advice such as it’s good to read news or to find helpful information to study.Teachers and parents all think the book is a very good idea.

Hong said the book will be a guide for teens using the Internet.She believes it will keep students away from bad websites.
