The Department of Public Health and Social Services (DPHSS) tested 64 individuals for COVID-19 on Tuesday, May 12, 2020, with conclusive results. Zero tested positive through DPHSS and 64 tested negative for SARS-CoV-2.

One additional case was confirmed by the Guam Regional Medical City (GRMC) and was reported earlier today. This evening’s results include samples from clinics, the Guam Memorial Hospital, the quarantine facility, and samples from the COVID-19 expanded testing at Guma Trankilidat in Tumon and St. Dominic’s Senior Care in Barrigada Heights. DPHSS has targeted areas where infection may occur due to lack of access to health care and in facilities where the elderly reside.

The DPHSS overall count also includes probable cases of COVID-19 and confirmed positive cases tested by the Naval Health Research Center (NHRC) in San Diego, the U.S. Naval Hospital (USNH) Guam, the Guam Memorial Hospital Authority (GMHA), Guam Regional Medical City (GRMC), the Guam National Guard (GUNG), and Diagnostic Laboratory Services (DLS).

To date, there have been 152 cases confirmed through COVID-19 testing provided with 5 deaths and 124 released from isolation. When a patient is released from isolation, he or she is no longer considered infectious. DPHSS uses CDC’s test-based criteria for releasing patients from isolation. This requires COVID-19 patients to have two consecutive negative tests at least 24 hours apart before being released from isolation. All remaining cases are in isolation.

Some cases that were previously released from isolation have returned to active isolation status after re-testing positive for COVID-19 through follow-up testing. To date, no additional cases have been linked to people released from isolation. As this is an evolving situation, information is subject to change with little to no notice.
