HFMD usually affects babies who are 1~4 years old, but adults can also be infected. Both EV71 and Cox A16 can cause HFMD, which usually starts with a slight fever followed by blisters (水泡) and ulcers (溃疡) in the mouth and rashes (皮疹) on the hands and feet.
It can be spread through people with the mucus (唾液) or feces (粪便) of an infected person. It usually appears during the summer and autumn months. HFMD isn’t Bird Flu, SARS or Mad Cow Disease, but it’s not a new one, either. It first appeared in New Zealand in 1957. About forty years later, it appears in Asia. It’s reported that it breaks out every 2 or 3 years.
HFMD is very terrible and there is no vaccine (疫苗) now, but we can do something helpful to prevent it. ‘Children with HFMD should seek medical treatment as early as possible’, experts say. They also suggest that parents keep the air fresh in a child’s room, which should be kept clean, tidy and dry. Children should be taught to wash their hands regularly. Staying away from crowded public places is also basic.

Without proper planning, tourism can cause problems. For example, too many tourists can crowd public places that are also enjoyed by the local people of a country. If tourists create too much traffic, the local people become unhappy. They begin to dislike tourists and to treat them impolitely. They forget how much tourism can help the country’s economy(经济). It is important to think about the people of a destination country and how tourism affects them. Tourism should help a country keep the customs and beauty that attract tourists. Tourism should also advance(推进) the well-being (health and happiness) of local people.
Too much tourism can be a problem. If tourism grows too quickly, people must leave other jobs to work in the tourism industry. This means that other parts of the country’s economy can suffer.
On the other hand, if there is not enough tourism, people can lose jobs. Businesses can also lose money. It costs a lot of money to build large hotels, airports, air terminals, first-class roads and other support facilities needed by tourist attractions. For example, a major international-class tourism hotel can cost as much as 50 thousand dollars per room to build. If this room is not used most of the time, the owners of the hotel will lose money.
Building a hotel is just a beginning. There must be many support facilities as well, including roads to get to the hotel, electricity, sewers to handle waste, and water. All of these support facilities cost money. If they are not used because there are not enough tourists, jobs and money are lost.
