1、新型冠狀病毒新型肺炎閱讀材料 A new Chinese coronavirus, a cousin of the SARS virus, has infected more than 200 people since the outbreak （爆發(fā)） began in Wuhan, China, in December. Scientist Leo Poon, who first decoded the virus, thinks it likely started in an animal and spread to humans. "What we know is it cause

2、s pneumonia （肺炎） and then doesn't respond to antibiotic （抗生素）treatment, which is not surprising, but then in terms of mortality （死亡率），SARS kills 10% of the individuals," Poon, a virologist （病毒學(xué)家）at the School of Public Health at The University of Hong Kong, said. The World Health Organization offer

3、ed guidance to countries on how they can prepare for it, including how to monitor for the sick and how to treat patients. Here are several things you should know about a coronavirus. 1 .What is a coronavirus? Coronaviruses are a large group of viruses that are common among animals. In rare cases,

4、 they are what scientists call zoonotic[, zaoa' naotik] （人畜共患?。?meaning they can be transmitted from animals to humans, according to the US Centers for Disease Control and Prevention. 2 .Coronavirus symptoms （癥狀） The viruses can make people sick, usually with a mild （輕度）to moderate （中度）upper resp

5、iratory tract illness （上呼吸道疾?。?，similar to a common cold. Coronavirus symptoms include a runny nose, cough, sore throat, possibly a headache and maybe a fever, which can last for a couple of days. For those with a weakened immune system, the elderly and the very young, there's a chance the virus cou

6、ld cause a lower, and much more serious, respiratory tract illness like a pneumonia or bronchitis [brog'kaitis]（支氣管炎）. 3 .There are a handful of human coronaviruses that are known to be deadly.

Severe Acute Respiratory Syndrome （嚴(yán)重急性呼吸綜合征）,also known as SARS, is the other coronavirus that can cause more severe s

8、ymptoms. First identified in the Guangdong province in southern China, according to the WHO, it causes respiratory problems but can also cause diarrhea [ dais'ria]（腹瀉）,fatigue （疲勞），shortness of breath, respiratory distress （呼吸窘迫）and kidney failure （腎衰）.Depending on the patient's age, the death rate

9、with SARS ranged from 0-50% of the cases, with older people being the most vulnerable. 4 .How it spreads? Viruses can spread from human contact with animals. Scientists think MERS started in camels, according to the WHO. With SARS, scientists suspected civet cats （貍貓） were to blame. When it comes

10、 to human-to-human transmission of the viruses, often it happens when someone comes into contact with the infected person's secretions [si'kri:j^9）n]（分泌物）. Depending on how virulent [ virslant] （有毒的）the virus is, a cough, sneeze or handshake could cause exposure. The virus can also be transmitted b

11、y touching something an infected person has touched and then touching your mouth, nose or eyes. Caregivers （護(hù)理人員）can sometimes be exposed by handling a patient's waste, according to the CDC. 疫苗研發(fā)的艱難戰(zhàn)役：多國專家爭分奪秒 針對武漢疫情的藥物，不僅中國在加緊攻關(guān)，全世界的醫(yī)學(xué)工作 者也在積極研發(fā)。不過相關(guān)疫苗的研制卻是一項(xiàng)很難在短時(shí)間內(nèi)實(shí)現(xiàn) 的工程。研制疫苗有多復(fù)雜？ 一起來聽今天的課程講解。

Will It Help? 研究人員正加緊研制冠狀病毒疫苗，會(huì)有用嗎？ By Knvul Sheikh and Katie Thomas In the early days of January, as cases of a strange, pneumonia-like illness 1( reporte) in China, researchers at the National Institutes of Health 2(ready) thems

13、elves to hunt for a vaccine to prevent the new disease. 一月初，隨著一種奇怪、類似肺炎的疾病在中國出現(xiàn)，美國國家 衛(wèi)生研究院的研究人員做好了準(zhǔn)備去鉆研預(yù)防該疾病的疫苗。 Scientists in Australia are also working on vaccine candidates to stop the spread of the disease. 澳大利亞的科學(xué)家也正在研究備選疫苗，以阻斷疫情傳播。 3(historical), vaccines have been one of the greatest publ

14、ic health tools to prevent disease. But even as new technology, advancements in genomics and improved global coordination have allowed researchers to move 4 unprecedented speed, vaccine development remains 5 expensive and risky process. 歷史上，疫苗一直都是預(yù)防疾病最重要的公共衛(wèi)生工具之一。技 術(shù)革新、基因?qū)W進(jìn)步以及全球合作的加強(qiáng)，使得研究人員以前所未有 的速

16、樂觀的情況下，任何疫苗從研發(fā)到面向公眾至 少需要一年，而大部分情況下這個(gè)過程可能花費(fèi)更長時(shí)間。 With each new outbreak, scientists 9(typical) have to start from scratch. After the SARS outbreak in 2003, it took researchers about 20 months from the release of the viral genome to get a vaccine ready for human trials. By the time an epidemic caused

Now, they hope the joint efforts will cut that time in half. 通常來說，每當(dāng)新的疫情爆發(fā)，科學(xué)家就得從頭開始。2003年 SARS爆發(fā)后，從公布病毒基因組到獲得一種可以進(jìn)行人體試驗(yàn)的疫 苗，研究人員花了約20個(gè)月的時(shí)間。到2015年寨卡病毒引發(fā)疫情時(shí)， 這一時(shí)間線被縮短為6個(gè)月?，F(xiàn)在，他們希望通過共同的努力，讓這 個(gè)時(shí)間再縮短一半。 (c) 2020
