Hunan Daily·New Hunan Client, August 2 (Reporter Zhang Chunxiang, Correspondent Zhang Yana Li Shikang) The reporter learned today that since the first local case of new coronary pneumonia in 2021 was obtained in our province on July 28, the Hunan Provincial Center for Disease Control and Prevention has Completed the sequencing of the genomes of 20 cases of Delta Covid-19
20 samples have been sequenced in 5 days
20 samples have been sequenced in 5 days According to Zhan Zhifei, chief of the Laboratory Department of the Provincial Center for Disease Control and Prevention, genome sequencing can obtain the genome sequence information of new and unknown viruses at the first time, and has become an important tool for studying disease outbreaks
By detecting the whole genome sequence of the new coronavirus, and then comparing this sequence with the data in the database through an algorithm, it is possible to preliminarily determine its geographic origin
In the face of this epidemic, Hunan Province’s CDC has sequenced 20 samples since the first local case of new coronary pneumonia in 2021 was obtained in Hunan Province on July 28
Complete viral gene sequencing and traceability within 24 hours
Complete viral gene sequencing and traceability within 24 hours "After the new coronavirus sample is sent to the laboratory, it usually needs to go through multiple steps to complete the test
After the virus gene sequence determination is completed, the staff will immediately perform bioinformatics analysis, compare the virus sequence with the sequence in the database, check for mutation sites, and compare homology
"At present, the Hunan Provincial Center for Disease Control and Prevention has high-throughput second- and third-generation sequencing capabilities for the new coronavirus genome, providing strong technical support for the identification, traceability, prevention and control of the new coronavirus epidemic and other infectious disease pathogens in Hunan Province
Sequencing results are highly homologous to Nanjing
Sequencing results are highly homologous to Nanjing On July 28, since receiving the sequencing of the first local case of new coronary pneumonia in 2021, the Provincial Center for Disease Control and Prevention immediately organized professional and technical personnel to carry out sequencing work day and night, through library preparation, cluster generation, computer sequencing and Data comparison and analysis showed that all the specimens that have completed sequencing results are Delta strains
According to the latest epidemic report, Hunan Province has reported a total of 22 confirmed cases of new coronavirus pneumonia from 0:00 on July 20 to 24:00 on August 1, 2021 (3 cases imported from abroad)
