COVID-19 pandemic in Guam

Guam, one of the external territories of the United States of America confirmed its first case of the COVID-19 pandemic on March 15, 2020, and the first death on March 22. The Government of Guam ordered the general lockdown of the island in mid-March. Governor Lou Leon Guerrero announced the implementation of a four-step "Pandemic Condition of Readiness" (PCOR) on April 30, 2020. Travelers to Guam from designated high-risk areas must provide a recent negative COVID-19 test or undergo mandatory quarantine in a government-approved facility. Guam moved from PCOR 1 to PCOR 2 on May 10, allowing some business activity with restrictions, and then to PCOR 3 on July 20. An outbreak in mid-August was not controlled for several months, resulting in the 7-day rolling test positivity rate to spike above 15% in early October 2020, as well as infections in both the Governor and Lieutenant Governor. Guam announced a return to the lockdown conditions of PCOR 1 on August 14 to control the outbreak, which was not loosened to PCOR 2 until January 15, 2021. It was further relaxed to PCOR 3 on February 21, 2021. From December 2020 to July 2021 cases stayed very low until a surge in August 2021 largely as a result of the delta variant. By October 2021, 90% of the population was vaccinated.^[2]

By May 7, 2021, there had been 8,023 confirmed and suspected cases, resulting in 139 deaths. 95 cases were in active quarantine.^[3] According to the weekly situation report issued on May 7, 2021, 59 cases had tested positive in the previous seven days, for a test percent positivity of 2.9%. Nine cases was identified through contact tracing and seven were travelers from other parts of the United States, of which six were identified in quarantine.^[4] The 1,156 cases and one death from the USS Theodore Roosevelt, which docked at Guam amid its 2020 outbreak, are counted separately.
