Coronavirus: These are the most common mutations in Greece
Extent of the Delta mutation
Completed by the National Network Genomics Supervision of the SARS-CoV-2 virus , operating under the coordination of PHEA , genomics analysis 891 samples were selected randomly or targeted and are period 02 July 2021 to 31 July 2021, the . From the control of 891 samples, a total of 823 samples with Variants Of Concern (VOC), 24 samples with Variants Under Monitoring and 3 samples with Variants of Interest (VOI) emerged.
Of the 823 samples with strains of special interest, 707 relate to the Delta strain , 90concern Alpha , 24 concern Beta and 2 concern Gamma. Of the 24 samples with strains under monitoring, all relate to strain B.1.1.318 (Variant E484K). Of the 3 samples with strain of interest, all relate to B.1.621 (VOI). In addition, 1 strain B.1.629, 1 strain B.1.575 and 1 strain B.1.1 (Variant E484K) were detected.
Since the launch of the National Network of Genomic Surveillance of the SARS-CoV-2 virus until today, a total of 26,555 samples of domestic cases have been tested in the country . Of these, 22,839 come from random sampling, 2,998 come from targeted sampling or sampling and for 718 samples the selection method is not available.
Among the 22 839 randomly selected samples in the territory, the four most common strains of interest or monitored isolated is the Alpha , with a percentage of 67.21% , followed by Delta with percentage 12.14%, the B.1.1.318(Variant E484K) with a percentage of 10.04% and the Beta with a percentage of 1.24% .
Of the 2,998 samples taken or selected in a targeted manner, 2,835 were found to be of special interest or under observation. Of these samples, 43.70% relate to B.1.1.318 (Variant E484K), 28.12% to Delta, 15.81% to Alpha, 6.70% to Beta, 0.13% to C.36 and 0.10% in Gamma.
In addition, a total of 238 strains of special interest or under surveillance or interest have been isolated from samples of imported cases, of which 113 relate to Alpha, 107 to Delta, 6 to Beta, 4 to B.1.1.318 (Variant E484K), 4 to B .1.621 (VOI), 1 in Eta, 1 in C.36, 1 in Kappa and 1 in B.1.623.
