  • 1. Bird Flu Build Up Pre-Reading Activities A: Talking And Thinking Answer these questions in pairs. 1. In the first part of the twentieth century (1900-1920) one event caused the deaths of 20-40 million people worldwide. Do you know what it was? 2. What do you know about this event? Were any of your family (grandparents, great- grandparents, etc.) affected by it? 3. What do you know about the 'bird flu'? Share your ideas with your partner. B: Find Your Other Half Your teacher is going to give you some background information on part of today's topic. You will be given a piece of paper with half a sentence with some information about the topic. Your part of the sentence may have a word or words that you do not know the meaning of. Use your dictionary if you need to. Make sure you understand your part of the sentence as you may be asked to explain it later! Someone else in the class has the other half of your sentence. Memorize your sentence half and then put the paper away. When your teacher gives a signal, stand up and mingle with other students. Tell other students your sentence half and listen to theirs. Try to find the person who has the other half of your sentence. When you find your partner, sit down with your partner and talk about what your sentence teaches you about the topic. When everyone in the class has found their partner, pairs of students should stand up and say their sentence. Take turns doing this until everyone in the class has said their sentence. Reading Activities A: Understanding The Main Idea Read Part One of Article One and decide which of the following is the main idea: 1. H5N1 may start the next worldwide flu pandemic. 2. The human strain of H5N1 is showing resistance to Tamiflu. 3. Relenza may be a good alternative to Tamiflu. 4. Drug manufacturers need to make other varieties of Relenza.
  • 2. Article One Part One Bird flu 'resistant to main drug' HONG KONG, China Fri 30 Sep (Reuters) -- A strain of the H5N1 bird flu virus that may unleash the next global flu pandemic is showing resistance to Tamiflu, the antiviral drug that countries around the world are now stockpiling to fend off the threat. Experts in Hong Kong said on Friday that the human H5N1 strain which surfaced in northern Vietnam this year had proved to be resistant to Tamiflu, a powerful antiviral drug which goes by the generic name, oseltamivir. They urged drug manufacturers to make more effective versions of Relenza, another antiviral that is also known to be effective in battling the much feared H5N1. Relenza is inhaled. "There are now resistant H5N1 strains appearing, and we can't totally rely on one drug (Tamiflu)," William Chui, honorary associate professor with the department of pharmacology at the Queen Mary Hospital in Hong Kong, told Reuters. Chui was referring to the Tamiflu- resistant strain of H5N1 in Vietnam. Chui also said general viral resistance to Tamiflu was growing in Japan, where doctors habitually prescribe the drug to fight the common influenza. "Manufacturers should think about producing an injectable form of Relenza because resistance to Tamiflu has been seen in Japan and Vietnam. Also with injections, high doses can be given where necessary and onset time is a lot faster," Chui said. (Continued/...)

Drugs that are administered intravenously can be better absorbed in patients who have stomach and acidity problems, another expert said. 2. "We don't have to worry about absorption, injections take drugs right 5. While the H5N1 virus is now mostly passed directly from bird to human, health experts have warned that it is just a matter of time before it mutates into a form that is easily transmissible between people. When that happens, it may result in as many

Intravenous Relenza would also ensure faster onset, which would be critical in patients who are seriously ill. 4. "Orally taken drugs take three to four hours to reach maximum blood concentration and three to four hours is very critical in severe cases. But injectable Relenza takes only 30 minutes to reach maximum blood concentration, this is a huge difference," Chui said. With an intravenous antiviral, doctors can also vary the doses. as 150 million human deaths. 6. Two reports in The Lancet medical journal this month said that resistance to anti-flu drugs was growing worldwide. 7. In places such as China, drug resistance exceeded 70 percent, suggesting that drugs like amantadine and rimantadine will probably no longer be effective for treatment or as a preventive in a pandemic outbreak of flu, the reports said. Article © 2005 Reuters Limited. Lesson © 2005 www.english-to-go.com C: Reading And Matching Read Parts One and Two of Article One again and match these names with the correct information. 1. H5N1 2. Tamiflu 3. William Chui 4. Relenza 5. Raymond Mak 6 . The Lancet a. recommends that intravenous drugs will be more effective for patients with stomach problems b. the antiviral drug that countries are hoping will fight the bird flu c. encourages drug companies to produce new versions of antiviral drugs d. the bird flu virus, which humans usually catch from birds e. another antiviral drug which the patient takes by breathing it in f. a journal that has reported that there is increasing resistance to antiviral drugs D: Complete The Summary Read part of another article (Article Two) about the bird flu. This was written in 2004. Use the words below to fill the gaps in the summary as you read Part One of Article Two.

Article Two Part One PROTECTIVE MEASURES LONDON Tue Jan 27 (Reuters) - The World Health Organization has described the avian virus rampaging through Asia as a serious global threat to human health and has urged governments to provide funds and technical assistance to countries. Professor Albert Osterhaus, a leading virologist at Erasmus University in Rotterdam, Osterhaus says it is time to update global pandemic preparedness plans: "No country in the world is fully prepared for that." The influenza pandemic of 1918, the biggest the world has seen, killed 20- 40 million people worldwide. Scientists have warned about the threat of the next global pandemic for years. In 1997 six people died in Hong Kong during an outbreak of avian flu and 1.4 million birds were slaughtered. "This is really a warning for a pandemic outbreak," Osterhaus said, referring the latest avian flu outbreak. "The chances of this happening are not very big. But even a small chance of something as horrendous as a pandemic flu outbreak is something we should take seriously." (Continued/...) Article © 2004 Reuters Limited. Lesson © 2005 www.english-to-go.com E: True or False Read Part Two of Article Two and decide whether the statements below are true (T) or false (F). 1. Migratory birds may have originally passed on a flu virus to domestic poultry. The virus then mutated and spread. 2. Professor Anderson believes that it is necessary to set up some way of recording where livestock are transported worldwide. 3. SARS is an example of a virus which was passed from animals to humans, killing thousands of people. 4. Professor Anderson believes that scientists must work together to research antivirals and vaccines. Article Two Part Two
  • 5. (.../Continued) Scientists are still unclear about how bird flu emerged. Although more in-depth research needs to be done, Osterhaus believes it was transmitted by migratory birds to domestic poultry and then "heated up" or mutated and spread from flock to flock. Why most of its victims are children is also puzzling but the virus is known to be excreted in the feces of birds which could provide some clues. With animal illnesses posing such serious threats to humans, Imperial's Anderson stressed the need for better monitoring of infectious disease outbreaks in animals and a method of tracking the movement of livestock around the world. The SARS (Severe Acute Respiratory Syndrome) virus, which jumped from animals to humans, killed hundreds and infected thousands. "We've got to invest more in international surveillance and cooperation and to develop research capabilities...to develop a diagnostic method quickly and to look for antivirals and vaccines quickly," he added. Osterhaus echoed the urgency of improving the speed with which vaccines can be developed and produced.

  • 6. B: Language Part One: Read these sentences from Article Two. "Although more in-depth research needs to be done, Osterhaus believes it was transmitted by migratory birds to domestic poultry and then 'heated up' or mutated and spread from flock to flock." Although links two clauses to make one sentence and contrast two ideas. It is put at the beginning of the less important clause with the most important clause in the other part of the sentence. It is followed by a subject and a verb. Here are the ideas that were linked in the sentence above. More in-depth research needs to be done (into how the avian virus originated). Osterhaus believes the avian virus was transmitted by migratory birds to domestic poultry... In the sentences below, the words have been jumbled up.

  • 7. TEACHERS' NOTES AND ANSWER KEY Please Note: This lesson has 3 linked reading and grammar activities for your students to do online at http://www.instantworkbook.com. To view the exercises, click on the blue icon next to this lesson description in the teachers' room. Pre-Reading Activities A: Talking And Thinking - Notes 1. Students may incorrectly answer ' World War 1'. However, this war killed around 10 million people. This question introduces students to the topic of contagious diseases and their effect globally. 2. One Internet site with useful information on this topic is: http://www.stanford.edu/group/virus/uda/ A: Talking And Thinking - Answers 1. The influenza pandemic of 1918-1919, which occurred in the aftermath of World War 1. (Figures vary but estimates say that over 20 million people lost their lives in this epidemic.) 2. Answers will vary. B: Find Your Other Half - Notes Cut up and separate the sentences below. If you have fourteen students, give one half to each student. If you have fewer students than this, you may remove one of the sentences and not use it. If you have an odd number of students, you can take one of the halves yourself. (If you need more sentences because you have more than fourteen students in your class, here are two extras: Children are most vulnerable to the flu,... / ...but the elderly and people with lung disease are also more at risk. / Flu viruses change each year and are often transmitted by people... / ...in places like offices, schools and other meeting places.) Mix the sentence halves up and then give them out with each student getting either the beginning or ending of a sentence. Encourage them to use their dictionaries to find the meanings of unknown words as some of these words are repeated in today's article. Students mingle and say their sentence halves aloud to each other and find the person who has the other half of their sentence. (They walk around and talk to other students to find out what information they have.) They are not allowed to read them out but must have learned them off by heart. You may like to set a time limit or allow the activity to continue until everyone has found their partner. Then students stand up in their pairs and say their sentence to the class. Make sure each student speaks clearly and loudly so that everyone can hear. (The sentences do not have to be said in any particular order.) If there are any sentences that were not used from the mingling part, you could read them aloud yourself at this stage, or ask volunteers to do it. Alternative activity: This can be a pairwork activity with each pair getting a complete set of sentences and then trying to match each beginning with the correct ending.

B: Language - Notes Part One: Students may find this quite challenging, so you could make it a pair activity. Part Two: Check sentences for meaning and grammatical accuracy or ask students to self-edit in pairs, with you highlighting the errors, and pairs then working to try to correct the errors. B: Language - Answers Part One 1. Although scientists are studying the bird flu intensively, they have not yet been able to develop a vaccine to fight it. 2. Although scientists have been warning people of the threat of a global pandemic, not enough has been done to develop systems of international scientific cooperation. 3. Although tracking the movements of animals worldwide could help control the spread of different diseases, this move is unlikely to be supported by most countries because of the cost involved. 4. Although the avian flu has not combined with human flu yet, there is a chance that this will happen. Part Two (Sample Answers only) 5. Although the doctor told me to get plenty of rest when I had flu last year, I ignored her advice and then had to go to bed for several weeks. 6. Although flu vaccines are offered to the elderly in my country, my mother refuses to have one as she doesn't believe that they work. 7. Although flu is highly contagious, many people with influenza do not worry about this, and do not isolate themselves from others until they have recovered. 8. Although people are worried about the bird flu in my country, chicken meat is still available in supermarkets and shops.
