18 COVID-19 cases with variants of concern identified


The Department of Public Health and Social Services has received eighteen (18) new results from virus samples collected on Guam between June 1 to June 16, which have undergone genome sequencing by the U.S. Centers for Disease Control and Prevention (CDC). DPHSS received the ninth set of results from the CDC. Eighteen (18) of the twenty-three (23) samples received were identified as Variants of Concern (VOC):

  • Sixteen (16) B.1.1.7 (Alpha)

  • One (1) B.1.351 (Beta)

  • One (1) B.1.617.2 (Delta)

To date, 179 SARS-CoV-2 virus samples have been submitted to the CDC for genome sequencing and identified a total of eighty-seven (87) COVID-19 cases infected with variants. DPHSS previously reported variants from results from the CDC and identified the following:

  • sixty-three (63) cases identified with the B.1.1.7 Alpha variant

  • fourteen (14) cases identified with the B.1.429 Epsilon variant

  • three (3) cases identified with the B.1.351 Beta variant
