The first case of the Brazilian coronavirus mutation (P.1.2 (VOC-21JAN-02), confirmed by the special laboratory. According to information from ethnos.gr, This is a man who lives in the center of Athens and his contacts are already being tracked.
Alarm to scientists about Nigerian mutation
However, what really causes great worry to scientists, is its prevailing trend Nigerian mutation in Central Greece, against her British mutation. Η νιγηριανή μετάλλαξη (B.1.1.318) is a combination of it Brazilian mutation with the African, while upward trends are also recorded in Attica.
The announcement of EODY
Completed by National SARS-CoV-2 Genomic Surveillance Network, operating under the coordination of EODY, the genomic analysis in 1.567 samples selected at random or targeted and relevant to the period 15 April to 27 May 2021. From the control of 1.567 samples, emerged as a whole 1.121 samples with strains of special interest (Variants Of Concern – VOC) and 345 samples with strains under monitoring (Variants Under Monitoring). Of the 1.121 samples with strains of special interest, the 1.112 concern B.1.1.7 (Uniform VOC 202012/01), 5 concern B.1.351 / 501Y.V2 (Uniform VOC 202012/02), 3 concern B.1.617.2 (VOC-21APR-02) and 1 αφορά στο P.1.2 (VOC-21JAN-02). Of the 345 samples with monitored strains, the 343 relate to strain B.1.1.318 (Variant E484K) and 2 concern C.36. In addition, emerged 8 samples with strain B.1.1.523 (Variant E484K), 2 with B.1.1 (Variant E484K), 1 with B.1.525 (Variant FUN-202102/03) and 1 with B.1.1.198 (Variant E484K).
Since its inception National Genomic Surveillance Network of SARS-CoV-2 virus to date have been tested in the territory as a whole 15.909 samples from domestic cases. From them 13.931 come from a random selection of samples, 1.325 they come from targeted download or sample selection and for 653 samples the selection method is not available.
Between 13.931 randomly selected samples in the territory, the three most common members of special interest or under investigation that have been isolated are B.1.1.7 (Uniform VOC 202012/01), with percentage 77,10%, followed by B.1.1.318 (Variant E484K) with percentage 7,62% and B.1.351 / 501Y.V2 (Uniform VOC 202012/02) with percentage 0,32% (Panel 4). The evolution of the relative frequency of sequenced samples by random sampling per species of strains, up to a week 20 is shown in the Diagram 1. From 1.325 samples taken or selected in a targeted manner, they have been found 1.185 officers of special interest or under supervision, of which 29,28% concern the strain B.1.1.7 (Uniform VOC 202012/01), 64,98% in the B.1.1.318 (Variant E484K) and 3,46% in B.1.351 / 501Y.V2 (Uniform VOC 202012/02).
In addition, have been isolated altogether 106 strains of special interest or under investigation or interest from samples of imported cases, of which 100 concern B.1.1.7 (Uniform VOC-202012/01), 4 in B.1.351 / 501Y.V2 (Uniform VOC 202012/02), 1 in B.1.525 (Variant FUN-202102/03) and 1 in B.1.617.1 (FUN-21APR-01).
