Seasonal influenza is characterized by a sudden fever, cough, headache, muscle and joint pain, sore throat and runny nose. Most people recover from fever and   1  symptoms within a week without requiring medical attention. But influenza can  2  severe illness or death in people at high risk. The time from infection to illness is about two days.

Yearly influenza epidemics can  3   affect all age groups, but the highest risk of complications occur among children younger than age two, adults age 65 or older, and people of  4   age with certain medical conditions, such as chronic heart, lung, kidney, liver, blood or metabolic diseases, or weakened immune systems.

Seasonal influenza  5   easily and can sweep through schools, nursing homes or businesses and towns. When an   6    person coughs, infected droplets get into the air and another person can breathe them  7    and be exposed. The virus can also be spread by hands infected with the virus.  8    transmission, people should cover their mouth and nose with a tissue when coughing, and  9   their hands regularly.

Drugs for influenza are   10   in some countries and effectively prevent and treat the illness. Some influenza viruses develop  11    to the antiviral medicines, limiting the effectiveness of treatment.

Influenza epidemics occur    12   during autumn and winter in temperate regions. Illnesses result in hospitalizations and deaths mainly among high-risk groups. Worldwide, these annual epidemics result in about three to five million   13     of severe illness, and about 250 000 to 500 000 deaths.

Influenza can cause serious public health and economic problems. In   14    countries, epidemics can result in high levels of worker absenteeism and productivity   15   .   16    most people recover from a bout(轮) of influenza, there are large numbers of people who need hospital treatment and many   17    die from the disease every year.   18     is known about the effects of influenza epidemics in developing countries.

The most    19   way to prevent the disease or severe outcomes from the illness is vaccination. Vaccination is especially important for people at higher risk of serious influenza complications, and for people who live with or care  20    high risk individuals.

An 18th-century statesman Edmund Burke once said, “All that is needed for the success of a misguided cause is that good people do nothing.” One such cause now seeks to end biomedical research because of the theory that animals have rights to decide whether to be used in research. Scientists need to respond forcefully to animal rights advocates, whose arguments are puzzling the public and threatening advances in health knowledge and care. Leaders of the animal rights movement attack biomedical research because it depends on public funding, and few people understand the process of health care research. Hearing false reports of cruelty to animals in research settings, many are puzzled that anyone would harm an animal on purpose.
For example, a grandmotherly woman setting up an animal rights booth at a recent street fair was giving out sheets that encouraged readers not to use anything that comes from or is tested in animals－no meat, no fur, no medicines. Asked what will happen when epidemics(传染病) return, she said. “Don’t worry, scientists will find some way of using computers.” Such well-meaning people just don’t understand.
Scientists must communicate their message to the public in an understandable way－in human terms, not in the language of biology. We need to make clear the connection between animal research and a grandmother’s organ replacement, a father’s bypass operation, a baby’s vaccinations(接种疫苗), and even a pet’s shots. To those who know nothing about the animal research that was needed to produce these treatments, as well as new treatments and vaccines, animal research seems wasteful at best and cruel at worst.
Much can be done. Scientists could give middle school lessons and present their own research. They should be quick to respond to letters to the editor, in case animal rights misinformation goes unchallenged and gains a false appearance of truth. Research institutions could be opened to tours, to show that laboratory animals receive humane care. Finally, because there are a lot of patients, the health research community should actively recruit(招募) not only well-known personalities such as Stephen Cooper, who has made courageous statements about the value of animal research, but all who receive medical treatment. If good people do nothing, there is a real possibility that uninformed citizens will wipe out the precious of medical progress.
