On Friday, DPHSS received sixty-seven (67) new results from virus samples collected on Guam between July 25 to August 10, which have undergone genome sequencing by the U.S. Centers for Disease Control and Prevention (CDC).
DPHSS received the tenth set of results from the CDC. Eight (8) of the sixty-seven (67) samples received were identified as Variants Being Monitored (VBM) while fifty-nine (59) of the sixty-seven (67) were identified as the Delta Variant of Concern (VOC).
Take note that the 59 identified Delta variants were in the time frame when the latest COVID-19 surge on island started.
The breakdown is as follows:
Eight (8) B.1.1.7
Forty-three (43) AY.2 sub-lineages
o Forty-two (42) AY.25
o One (1) AY.26
Ten (10) B.1.617.2 (Delta)
Three (3) AY.1 sub-lineages
o Three (3) AY.14
Three (3) AY.3 alias B.1.617.2.3
To date, 246 SARS-CoV-2 virus samples have been submitted to the CDC for genome sequencing and identified a total of one hundred five (105) COVID-19 cases infected with variants. DPHSS previously reported variants from results from the CDC and identified the following:
seventy-nine (79) cases identified with the B.1.1.7 Alpha variant
fourteen (14) cases identified with the B.1.429 Epsilon variant
four (4) cases identified with the B.1.351 Beta variant
seven (7) cases identified with the B.1.617.2 and AY.3 Delta variant
one (1) case identified with the P.1 Gamma variant
On September 21, 2021, the U.S. Government SARS-CoV-2 Interagency Group added a new variant classification designated as Variants Being Monitored (VBM). This class includes previously designated Variants of Interest (VOI) or Variants of Concern that are no longer detected, or are circulating at very low levels in the United States and do not pose a significant risk to public health in the United States.
These include the Alpha, Beta, Epsilon, Eta, Gamma, Iota, Kappa, 1.617.3, Mu, and Zeta variants.
The Delta variant is classified as the only VOC.
There are currently no variants classified as Variants of High Consequence (VOHC).
