VOA慢速英语 通过蚊子传播的疾病

　　The World Health Organization says about fifty million people suffer from dengue fever each year. There is no cure. Children may develop a kind of the disease that is not serious. They may have a high body temperature and some areas of skin may turn red.

　　VOICE ONE:

　　Older adults suffer from dengue fever much more. They may develop reddish skin and lose their sense of taste. They also may have pain in the head or behind their eyes. And they may experience pain in joints such as the elbow or knee. This kind of joint pain is the reason why dengue fever is sometimes known as breakbone fever.

　　The most severe kind of the disease is called dengue hemorrhagic fever. People who have this disease bleed from the nose or other openings in the body. Dengue hemorrhagic fever kills about five percent of all people it infects. The only treatment involves controlling the bleeding and replacing lost body fluids.

　　VOICE TWO:

　　Yellow fever is another disease carried by mosquitoes. There are no effective drugs against yellow fever. Doctors can only hope that a person's defense system is strong enough to fight the disease. Yellow fever is found mainly in Africa, the northern part of South America and the islands of the Caribbean Sea. The World Health Organization says there are an estimated two hundred thousand cases of the disease and thirty thousand deaths each year.
