Viral Infection Test
Rapid and accurate detection of the virus is the key to epidemic prevention and control. On December 31, 2019, the High-level Expert Group of the NHC was dispatched to Wuhan, who soon identified that the pathogen of this particular viral pneumonia case was a novel coronavirus.
The NHC immediately established a "daily report and zero report" mechanism throughout the country, and distributed novel coronavirus nucleic acid testing kits, requiring all localities to reinforce testing, make every effort to treat patients, and update the public about the confirmed cases and progress in epidemic prevention and control without delay. At that time, nucleic acid detection was the main basis for the diagnosis of the novel coronavirus pneumonia.
On January 22, the NHC announced that negative nucleic acid test results cannot rule out novel coronavirus infection, and various factors that may falsely produce negative results still need to be considered.
The NHC also sent work teams to different provinces and equivalent administrative regions to guide epidemic prevention and control efforts.
Meanwhile, the Chinese government took the initiative to inform the WHO and relevant countries of the developments of the epidemic and progress in epidemic control, and immediately shared the gene sequence of the novel coronavirus with the WHO.
病毒檢測實驗
快速準確地檢測到病毒是防控的關鍵。2019年12月31日，國家衛生健康委高級別專家組赴武漢開展相關檢測核實工作，初步確定此次不明原因病毒性肺炎病例的病原體為新型冠狀病毒。
國家衛健委隨即在全國建立“日報告、零報告”制度，同時下發新冠病毒核酸檢測試劑盒，要求各地加強檢測，全力救治患者，及時發布確診病例及疫情防控信息。核酸檢測是目前診斷新冠病毒肺炎的主要依據。1月22日，國家衛健委明確指出，核酸檢測結果陰性不能排除新冠病毒感染，仍需要考慮可能產生假陰性的各種因素。為遏制疫情發展，國家衛健委向全國各省派出工作組，指導做好疫情防控相關工作。與此同時，中國政府主動向世界衛生組織和有關國家及時通報疫情信息和防控工作進展，第一時間與世界衛生組織共享新冠病毒基因序列。
