Successful Isolation of a Novel Coronavirus
The isolation of virus strains helps to speed up the development of rapid diagnostic reagents, which is of great significance for the development of vaccines and drugs. After cases of pneumonia by unknown cause occurred in Wuhan, the Chinese government quickly deployed the work of virus analysis, research and development of testing reagents and vaccine development.
After receiving the samples, the Chinese Center for Disease Control and Prevention obtained positive results of real-time fluorescence RPA in 3 hours and full-length genomic sequence of the virus in 24 hours. On January 4, 2020, a high specific detection reagent was successfully developed. On the evening of January 7, a novel coronavirus was successfully isolated from clinical samples and environmental samples, and the information about the first novel coronavirus strain in the world was released on January 24. After that, Zhong Nanshan's team separated novel coronavirus from the feces and urine samples of confirmed patients, which has an important warning and guiding significance for public health security.
The WHO-China Joint Mission on COVID-19 held a press conference on February 24, and announced that the host of the novel coronavirus has not yet been determined, the novel coronavirus is a new pathogen, and people of all ages have no immunity and are generally susceptible to infection.
新冠病毒成功分離
病毒毒株的分離有助于加快研發快速診斷的試劑，對疫苗研制和藥物研發具有重要意義。武漢出現不明原因肺炎病例后，中國政府迅速部署開展病毒分析、檢測試劑研發和疫苗研制等工作。
中國疾控中心在接到標本后，3小時獲得實時熒光定量檢測陽性的檢測結果，24小時獲得病毒全長基因組序列，2020年1月4日成功研制出高特異性檢測試劑，1月7日晚分別從臨床樣本和環境樣本中成功分離病毒，1月24日全球首發第一株新冠病毒毒株信息。之后，鐘南山團隊從新冠肺炎患者的糞便及尿液標本中分離出新冠病毒，此舉對公共衛生安全防控具有重要警示和指導意義。2月24日，中國—世界衛生組織新冠肺炎聯合專家考察組召開新聞發布會，稱目前新冠病毒宿主仍未確定，強調新冠病毒是一種新的病原體，各年齡段人群均無免疫力，普遍容易感染。
