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.

By May 7, 2021, there had been 8,023 confirmed and suspected cases, resulting in 139 deaths. 95 cases were in active quarantine. 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. The 1,156 cases and one death from the USS Theodore Roosevelt, which docked at Guam amid its 2020 outbreak, are counted separately.
