Should You Self-Isolate if You Suddenly Lose Your Sense of Smell? Here's What We Know Part 1
如果突然失去嗅覺，你是否應該自我隔離？以下是我們所知道的（上）
Waking up and not being able to smell the coffee could be a sign of COVID-19. The World Health Organization recently announced that a sudden loss of sense of smell (anosmia) should be added to the symptoms of COVID-19.
醒來後聞不到咖啡的味道可能是新冠肺炎的徵兆。世界衛生組織最近宣佈突然間失去嗅覺（嗅覺缺失症）應該被納入新冠肺炎的症狀。
The UK government has just done that, stating: "From today, all individuals should self-isolate if they develop a new continuous cough or fever or anosmia."
英國政府剛剛開始這樣做，並聲明：“從今天開始，所有人如果持續出現咳嗽，發燒，嗅覺缺失，都應自我隔離。”
The inclusion of sudden anosmia is important as it may be an early – and sometimes the only – symptom of COVID-19 infection. It is also a symptom, like fever, that we can detect ourselves without a laboratory test. The indications are that if we were all to respond to this cue by self-isolating, we could reduce the spread of the virus.
納入突然的嗅覺缺失是很重要的，因爲它可能是新型冠狀病毒肺炎的早期症狀，有時甚至是唯一的症狀。就像發燒一樣，這是一種我們無需實驗室檢查就可以在自我檢測的症狀。有跡象表明，如果我們所有人都通過自我隔離來響應這一號召，我們就可以減少病毒的傳播。
An early clue that a loss of smell might be related to COVID-19 came in early March 2020 from a Facebook post about an ear, nose and throat (ENT) doctor who suddenly lost his sense of smell. What followed was a gradual accumulation of evidence linking anosmia to COVID-19.
最早與新冠病毒有關的嗅覺消失的線索來自2020年3月一個突然失去嗅覺的耳鼻喉科醫在發佈的臉書的帖子中，隨後嗅覺缺失與新冠病毒相關聯的證據不斷積累。
Membership of closed Facebook groups dedicated to those experiencing smell loss grew exponentially, Google searches for "anosmia" increased, and high-profile cases were reported in the news.
爲失去嗅覺而專門設立的封閉的臉書羣組裏的人數呈指數級增長。谷歌搜索“嗅覺缺失”的檢索記錄不斷增加，新聞中也報道了一些關注度很高的案例。
ENT doctors saw an increase in patients reporting anosmia and started to publish case studies based on the experience of their patients – many of them healthcare professionals.
耳鼻喉科的醫生髮現上報有嗅覺缺失的患者有所增加，並開始根據一些患者的經歷發佈案例研究，其中許多患者是醫療保健的專業人員。
One, a neurosurgeon, reported anosmia with no other symptoms. Two days later he tested positive for COVID-19.
其中一位是神經外科醫生，報告有嗅覺缺失但是沒有其他症狀。兩天後， 他的新型冠狀病毒肺炎檢測呈陽性。
The sudden onset of anosmia was described as a new finding that may distinguish COVID-19 from the common cold or flu. An early statement was issued by ENT-UK and the British Rhinology Society calling for anosmia to be recognised as a marker of the virus.
突然發作的嗅覺缺失可視爲一個新的發現，可能將新冠肺炎和普通感冒或流感區分開來。英國耳鼻喉科和英國鼻科學協會發布了一份早期聲明，呼籲將嗅覺缺失症視爲該病毒的標誌。
However, while the case studies and anecdotes are compelling, they lack the large datasets of a scientific study.
然而，儘管案例研究和軼事令人信服，但它們缺乏科學研究的大數據集。
The first large dataset came from Iran. It was a home-based study of 10,000 people showing a correlation between anosmia and COVID-19. Results from the second large dataset were published by a team based at King's College London.
第一個大數據集來自伊朗。這是一個針對10000人的家庭的研究調查，該研究表示嗅覺缺失與新冠肺炎之間存在相關性。倫敦國王學院的一個團隊發佈了第二個來自大數據集的結果。
Their COVID Symptom Study app showed that 65 percent of those who tested positive for the disease also had a loss of smell and taste, and this symptom was by far the best predictor of COVID-19. And preliminary results from the first survey of the Global Consortium for Chemosensory Research (GCCR) showed that those reporting COVID-19 symptoms had an average drop of 80 percent in their ability to smell.
他們的新冠肺炎症狀研究應用程序顯示，在新冠肺炎檢測呈陽性的人中，有65％的人也有嗅覺和味覺的缺失。迄今爲止，這種症狀是新冠肺炎最佳的預測指標。全球化學感官研究聯合會的首次調查的初步結果顯示，患有新冠肺炎的人的嗅覺能力平均下降80％。
