The invention relates to the technical field of
virus nucleic acid detection methods, and particularly relates to an RT-LAMP
nucleic acid detection primer group of SARS-CoV-2 and a closed SARS-CoV-2 isothermal amplification
nucleic acid detection kit. According to the kit provided by the invention, nucleic acid extraction is not needed for
virus RNA of a
throat swab sample, and the sample can be directly amplified. The kit is a visual instant screening kit for the SARS-CoV-2 by a one-
step method. The kit has good specificity, can eliminate non-specific interference of other
coronavirus strains, is quick and efficient, and can complete detection within one hour. Large expensive and precise instruments and equipment are not needed, only a common
metal bath or water bath kettle is needed, detection cost is low, toxic reagents are not involved and closed operation is performed in the whole process, secondary
pollution is avoided, and safety of operators and an environment is ensured.
