鐘南山、李蘭娟院士團隊近日分別從新冠肺炎患者的糞便樣本中分離出新型冠狀病毒,這一發(fā)現(xiàn)證實了排出的糞便中的確存在活病毒,對于準確認識疾病的致病傳播機理,幫助全社會有針對性地做好防控,切斷疫情傳播途徑具有重要意義。
Researchers from multiple organizations, including the State Key Laboratory of Respiratory Disease under Guangzhou Medical University, have successfully isolated a strain of virus from swab sample of an infected patient's feces, said Zhao Jincun, a member of Chinese respiratory expert Zhong Nanshan's research group, at a press conference Thursday.
鐘南山院士團隊專家、呼吸疾病國家重點實驗室副主任趙金存教授介紹,廣州醫(yī)科大學呼吸疾病國家重點實驗室等多個研究機構的研究人員,從一例新冠肺炎患者的糞便拭子標本中分離到一株新型冠狀病毒。
The swab sample was provided by the Fifth Affiliated Hospital of Sun Yat-Sen University, said Zhao, also a professor with the laboratory.
該樣本是由珠海中山大學附屬第五醫(yī)院提供的糞便拭子標本。
Meanwhile, a research team led by Li Lanjuan, a renowned Chinese epidemiologist, also isolated novel coronavirus strains from stool specimens of infected patients. Three of the five feces samples tested positive, according to Wu Nanping, deputy director of the State Key Laboratory for Diagnosis and Treatment of Infectious Diseases, Zhejiang University.
我國知名病毒學家李蘭娟院士團隊近日也同樣從患者糞便樣本中分離到病毒。浙江大學傳染病診治國家重點實驗室副主任吳南屏教授介紹,研究人員從5份糞便樣本中分離到了3份新型冠狀病毒陽性。
趙金存表示,這個發(fā)現(xiàn)證實了排出的糞便的確存在活病毒,不過目前還沒有充分的證據(jù)說明存在糞口傳播(fecal-oral transmission)。
國家衛(wèi)生健康委新聞發(fā)言人、宣傳司副司長米鋒表示:
Transmission through means of respiratory and contact remain the major routes of the novel coronavirus spreading. Despite digestive tract problems of some patients, either as incipient symptoms or complications, the main clinical symptoms of the disease are fever, general weakness and dry cough, Mi said, adding that the coronavirus isolated from patients' feces is not yet illustrative to prove the change of the transmission route.
不管患者消化道癥狀是初發(fā)癥狀還是并發(fā)癥狀,發(fā)熱、乏力、干咳仍然是最重要的臨床表現(xiàn)。糞便中分離到病毒并不意味著該病主要傳播途徑發(fā)生變化,仍為呼吸道和接觸傳播為主。
Mi said that stomach and intestine symptoms, such as diarrhea, of some patients in the early stages, the positive test for the coronavirus nucleic acid in feces samples of patients and the isolated virus from patients' feces samples indicate the proliferation of the virus can happen in the digestive tract after infection.
部分病例早期的癥狀中有腹瀉等胃腸道的癥狀,患者糞便的標本中核酸檢測陽性或分離到病毒,提示感染新冠病毒后,病毒在消化道內也可以增殖。
注意個人和家庭衛(wèi)生
米鋒表示,戴好口罩和做好手衛(wèi)生(wearing masks and keeping hands clean)是最重要、最有效的防護措施,堅持勤洗手、規(guī)范洗手和手消毒(washing hands more frequently, in the right way and disinfection of hands),可以從根本上減少感染風險。
吳南屏建議:大家注意公共衛(wèi)生,多洗手、吃熟食,食物要洗凈燒透(make sure that food is thoroughly cleaned and well cooked),注意個人衛(wèi)生及必要的污水處理(sewage treatment)。
趙金存表示,提醒大家要更加重視個人和家庭的清潔,如便后洗手,注意下水道的通暢(make sure the plumbing system run smoothly),以避免有可能出現(xiàn)的糞便病毒的傳播。
