About the new strain of genomic epidemiologist dr. Gytis Dudas says: “P.1 is one of the three“ classic ”varieties of interest (the others are B.1.1.7 and B.1.351).
The risk presented by strain P.1 (‘Brazilian’) is similar to that of B.1.351 (‘South Africa’), with the E484K mutation in both strains because both strains reduce the effectiveness of neutralizing antibodies and increase the risk of infection in strains without this mutation, or vaccination with currently registered vaccines.
It is true that studies show that this effect is slightly weaker in the case of P.1 than in B.1.351.
A week ago, Latvia was the first in the Baltic States to confirm infection with the P.1 strain. The Latvian case involved a traveler returning from Italy. According to primary data from the National Public Health Center (NVSC), a person infected with this strain has visited abroad, so it is likely that the P.1 strain is not currently spreading in Lithuania.
In Europe, sequencing programs detect the P.1 variety quite frequently, but it is still less than 5%. all successive cases in Europe “.
512 samples were analyzed in the reference laboratory of the European Center for Disease Prevention and Control (ECDC), of which 469 cases belong to line B.1.1.7. These cases represent 99%. (299/303) Vilnius, 100 percent. (2/2) Alytus, 91 percent. (11/10) Utena, 100 percent. (15/15) Šiauliai, 54 percent. (15/28) Klaipeda, 95 percent. (72/76) Kaunas, 100 percent. (30/30) Marijampolė, 89 percent. (24/27) Panevėžys, 50 percent. (1/2) Tauragė and 50 percent. (1/2) Latest samples analyzed by Telšiai County ECDC. Likewise, 15 new cases of the B.1.620 virus line were identified in this laboratory.
A total of 7,525 samples have been sequenced and so far 4,000 cases of virus lines B.1.1.7, 14 B.1.351, 76 B.1.620 and 1 P.1 have been carried out in Lithuania, according to the sequencing project coordinated by NVSPL.
