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.
病毒检测实验
快速准确地检测到病毒是防控的关键。2019年12月31日，国家卫生健康委高级别专家组赴武汉开展相关检测核实工作，初步确定此次不明原因病毒性肺炎病例的病原体为新型冠状病毒。
国家卫健委随即在全国建立“日报告、零报告”制度，同时下发新冠病毒核酸检测试剂盒，要求各地加强检测，全力救治患者，及时发布确诊病例及疫情防控信息。核酸检测是目前诊断新冠病毒肺炎的主要依据。1月22日，国家卫健委明确指出，核酸检测结果阴性不能排除新冠病毒感染，仍需要考虑可能产生假阴性的各种因素。为遏制疫情发展，国家卫健委向全国各省派出工作组，指导做好疫情防控相关工作。与此同时，中国政府主动向世界卫生组织和有关国家及时通报疫情信息和防控工作进展，第一时间与世界卫生组织共享新冠病毒基因序列。
