[新聞] 中國發現新的流感病毒，有大爆發可能

BBC Flu virus with 'pandemic potential' found in China 中國發現具有爆發大流行潛力的新流感病毒 A滢ew strain of flu that has the potential to become a pandemic has been ident ified in China by scientists. 中國科學家發現新的具有爆發大流行的流感病毒珠。 It emerged recently and is carried by pigs, but can infect humans, they say. 此病毒來自豬隻，目前由豬隻帶原，但能傳染人類。 The researchers are concerned that it could mutate further so that it can spre ad easily from person to person, and trigger a global outbreak. 研究人員擔憂病毒可能會持續變異，產生人傳人的能力。 While it is not an immediate problem, they say, it has "all the hallmarks" of being highly adapted to infect humans and needs close monitoring. 雖然不造成立即威脅，但研究人員說此病毒具有演變成傳染人類的「所有特性」，因此必 須嚴加監控。 As it's new, people could have little or no immunity to the virus. 此為新的病毒，所以人類幾乎沒有免疫力。 後面自己看吧，反正鄉民都多益990，托福120，雅思9.0。 Pandemic threat A bad new strain of influenza is among the top disease threats that experts ar e watching for, even as the world attempts to bring to an end the current coro navirus pandemic. The last pandemic flu the world encountered - the swine flu outbreak of 2009 t hat began in Mexico - was less deadly than initially feared, largely because m any older people had some immunity to it, probably because of its similarity t o other flu viruses that had circulated years before. That virus, called A/H1N1pdm09, is now covered by the annual flu vaccine to ma ke sure people are protected. The new flu strain that has been identified in China is similar to 2009 swine flu, but with some new changes. So far, it hasn't posed a big threat, but Prof Kin-Chow Chang and colleagues w ho have been studying it, say it is one to keep an eye on. The virus, which the researchers call G4 EA H1N1, can grow and multiply in the cells that line the human airways. They found evidence of recent infection starting in people who worked in abatt oirs and the swine industry in China. Current flu vaccines do not appear to protect against it, although they could be adapted to do so if needed. Prof Kin-Chow Chang, who works at Nottingham University in the UK, told the BB C: "Right now we are distracted with coronavirus and rightly so. But we must n ot lose sight of potentially dangerous new viruses." While this new virus is not an immediate problem, he says: "We should not igno re it". The scientists write in the journal嘭roceedings of the National Academy of Sci ences濳hat measures to control the virus in pigs and closely monitor working p opulations should be swiftly implemented. Prof James Wood, Head of the Department of Veterinary Medicine at the Universi ty of Cambridge, said the work "comes as a salutary reminder" that we are cons tantly at risk of new emergence of pathogens, and that farmed animals, with wh ich humans have greater contact than with wildlife, may act as the source for important pandemic viruses https://tinyurl.com/yakzoqs2 抓穩了！ -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 101.10.134.247 (臺灣) ※ 文章網址: https://www.ptt.cc/bbs/Gossiping/M.1593472739.A.FA4.html ※ 編輯: muse87131 (101.10.134.247 臺灣), 06/30/2020 07:20:23
