For questions 8 10, complete the sentences With the information given in the passage. Influenza Influenza is caused by a virus transmitted from
5、 one person to another in droplets coughed or sneezed into the air. It is characterized by cold like symptoms plus chills, fever, headaches, muscle aches, and fatigue. Most people recover completely in about a week. In addition to humans, influenza occurs in pigs, horses, and several other mammals (
6、哺乳动物 ) as well as in certain wild and domesticated birds. At least some influenza viruses can jump from one species to another. For example, in late 1997 a strain of the influenza virus in chickens began to infect humans in Hong Kong, leading to a massive effect to remove the strain. Many millions o
7、f people develop the flu each year. In most years less than 1 percent of those infected die. Nonetheless, this translates into large numbers. The United States Centers for Disease Control and Prevention (CDC) estimates that influenza causes more than 20,000 deaths in the United States each year; com
8、bined, influenza and pneumonia (肺炎 )are among the nations ten leading causes of death. During epidemics and pandemics, death rates soar. The influenza pandemic that occurred between 1918 and 1919-the worse on record-killed about 500,000 people in the United States and more than 20 million people wor
9、ldwide. Symptoms and diagnosis Influenza is an acute disease with a rapid onset and obvious symptoms. After the influenza virus invades a persons body, an period of one or two days passes before symptoms appear. Classic symptoms include sore throat, dry cough, stuffed or runny no, se, chills, fever
10、with temperatures as high as 39 , aching muscles and joints, headache, loss of appetite, occasional nausea and vomiting, and fatigue. For most people flu symptoms begin to subside after two to three days and disappear in seven to ten days. However, coughing and fatigue may persist for two or more we
11、eks. Death from influenza itself is rare. But influenza can worsen underlying medical conditions, such as heart or lung disease. Invading influenza viruses produce inflammation (发炎 ) in the lining of the respiratory tract, damage that increases the risk that secondary infections will develop. Common
12、 complications include bronchitis, sinusitis, and bacterial pneumonia, occurring most frequently in the elderly, people on chemotherapy (化学疗法 ), and people with acquired immunodeficiency syndrome (AIDS) or another disease that compromises the immune system. If properly treated, these complications s
13、eldom are fatal. Because influenza is so common and exhibits standard symptoms, doctors often diagnose the illness based on the season and whether flu cases have recently been reported in the area. TO prove a diagnosis of influenza in a patient, the virus must be isolated from the persons nasal or c
14、ough secretions or blood and identified under a microscope. Treatment and prevention There is no specific cure for influenza. Recommended treatment usually consists of bed rest and increased intake of fluids until fever and other symptoms lessen in severity. Certain drugs have been found effective i
15、n lessening flu symptoms, but medical efforts against the disease focus chiefly on prevention by means of vaccines that create immunity. Vaccines A flu vaccine consists of greatly weakened or killed flu viruses, or fragments of dead viruses. Antigens (抗原 ) in the vaccine stimulate a persons immune s
16、ystem to produce antibodies against the viruses. If the flu viruses invade a vaccinated person at a later time, the immune system recognizes the antigens and quickly responds to help destroy the viruses. About 5 to 10 percent of people who receive a flu vaccine experience mild, temporary side effect
17、s, typically soreness at the injection site. Young children who have not previously been exposed to the influenza virus are most likely to have side effects. Flu viruses constantly Change so different virus strains must be incorporated in vaccines from one year to the next. Scientists try to provide
18、 a good match between the vaccine and the most serious virus strains circulating at the time. But because it takes months to manufacture and distribute vaccines, decisions on their composition must be made well before the start of each flu season. Each February experts at the World Health Organizati
19、on (WHO) recommend the composition of the vaccine for the forthcoming winter in the Northern Hemisphere; a second recommendation is made in September for vaccine to be used in the Southern Hemisphere. Typically vaccines contain antigens from three virus strains, usually two type A and one type B. Ac
20、cording to the CDC, the success of the flu vaccines varies from one person to another. In healthy young adults, the vaccines are 70 to 90 percent effective in preventing the disease, In the elderly and people with certain chronic medical conditions, the vaccines are less effective in preventing illn
21、ess but help reduce the severity of an infection and the risk of major complications or death. Studies show that flu vaccines reduce hospitalization by about 70 percent and death by about 85 percent among elderly people. Historic outbreaks Evidence suggests that all influenza viruses in mammals, inc
22、luding humans, derived from viruses in wild ducks and other birds. Some of these viruses could have been acquired by humans thousands of years ago. But medical historians know of no clearly identifiable influenza epidemics until large-scale outbreaks occurred in Europe in 1510, 1557, and 1580. The 1
23、580 outbreak also spread into Africa and Asia, making it the first known pandemic (广大地域流行 ). Pandemics have occurred periodically ever since. Major pandemics took place in 17294 1730, 173241733, 1781 1782, 183041831, 1833, and 1889-1890. The last of these, called the Russian flu because it reached E
24、urope from the east, was the first pandemic for which detailed records are available. In the 20th century, major pandemics occurred in 1918 1919, 1957 1958, and 1968 1969. The 1918 1919 pandemic was the most destructive in recorded history. It started as World War (1914 1918) was ending and caused 2
25、0 million deaths-twice as many deaths as the war itself. When and where the pandemic began is uncertain, but because Spain experienced the first major outbreak, the disease came to be called the Spanish flu. The virus was exceptionally deadly; many of the deaths were among young adults age 20 to 40,
26、 a group usually not severely affected by influenza. No additionally pandemics occurred during the 20th century, but public health experts expect that there will be more pandemics in coming years. While scientists do not yet know how to accurately predict flu outbreaks, they have established an inte
27、rnational network to track and monitor outbreaks so that health officials can take immediate preventive measures to avoid pandemics. The international network, called FluNet, consists of about 110 influenza centers in more than 80 countries and several World Health Organization (WHO) centers, all li
