Virus sample preservation solution, nucleic acid extraction reagent and viral nucleic acid extraction method

The invention discloses a virus sample preservation solution with a lysis function and a method for extracting viral nucleic acid. Since sample preservation and lysis are completed in one step, no additional lysis solution is needed, further diluting of a virus sample is prevented, the adding amount of the sample during the extraction process of viral nucleic acid can be increased, and the sensitivity of subsequent detection is improved. Meanwhile, because the preservation and lysis of the virus sample are completed in one step, the step of nucleic acid detection is removed, the process is optimized, and the efficiency of sample detection is improved. Compared with a conventional virus sample preservation solution such as a PBS buffer solution, the virus sample preservation solution has good preservation effect, more detection samples can be obtained, the detection sensitivity is improved, and the processing flow is simplified. 本发明公开了一种具有裂解功能的病毒样本保存液，及病毒核酸提取的方法。由于样本保存、裂解一步完成，无需另外加入裂解液，避免了病毒样本的进一步稀释，可以在病毒核酸提取过
