There are fourteen so far, the new cases of the Omicron mutation that have been identified in our country. The cases are rising at 17 in total along with the first three announced.
According with EODY These are three cases in Attica, two in Heraklion, Crete, three in Laconia, one in Chania and eight in Lassithi.
In particular, according to the announcement, out of 1,144 samples with executives of special interest, 1,130 concern the Delta executive, and 14 concern the Omicron.
Detailed data on mutations
Completed by the National Network of Genomic Surveillance of the SARS-CoV-2 virus, operating under the coordination of EODY, the genomic analysis in 1,173 samples that were randomly selected or targeted and concern the period 06 November 2021 to 13 December 2021.
From the control of 1,173 samples, a total of 1,144 samples with strains of special interest (Variants Of Concern – VOC) emerged. Of the 1,144 specimens of special interest, 1,130 relate to the Delta strain, and 14 relate to the Omicron (Table 3). Thirteen of the 1,130 Delta executives belong to the strain ΑΥ.4.2, which were located in the Regional Units of Argolida (7), Lassithi (3), Piraeus (2), and Serres (1).
The fourteen Omicron executives were identified in three imported cases in the Peripheral Units of Lassithi, the Central Sector of Athens and Heraklion and in eleven domestic cases in the Peripheral Units of Lassithi (7), Laconia (3) and Heraklion (1).
Since the launch of the National SARS-CoV-2 Genomic Surveillance Network, a total of 39,166 samples of domestic cases have been tested in the country. Of these, 34,886 come from random sampling, 3,539 come from targeted sampling or sampling and for 741 samples the selection method is not available. Among the 34,886 randomly selected samples in the territory, the four most frequently targeted or monitored strains isolated are Alpha with 44.61%, followed by Delta with 41.51%, B.1.1.318 (Variant E484K) with a percentage of 6.72%, and Beta with a percentage of 0.95%.
The evolution of the relative frequency of the randomly sampled samples by species sampling per week, up to week 48 is shown in Figure 9, while additional provisional data for weeks 49-50 are given. Of the 3,539 samples taken or selected in a targeted manner, 3,376 were found to be of special interest or under observation or interest. Of these samples, 37.02% relate to B.1.1.318 (Variant E484K), 36.93% to Delta, 15.23% to Alpha, 5.71% to Beta, 0.11% to C.36 , 0.11% in Omicron, 0.08% in Gamma, 0.08% in Eta, 0.08% in A.28 and 0.03% in Mu. In addition, a total of 439 strains of special interest or under surveillance or interest have been isolated from samples of imported cases, of which 300 relate to Delta, 113 to Alpha, 7 to Mu, 6 to Beta, 5 to Omicron, 4 to B.1.1.318 (Variant E484K), 1 in Eta, 1 in C.36, 1 in Kappa, and 1 in B.1.1 (Variant E484K).
