DPHSS COVID-19 Pilot Project Update 

DPHSS, in collaboration with the Government of Guam and federal and private partners, launched a COVID-19 Pilot Project Drive-Through/Walk-In Testing from 9 a.m. to 12:00 p.m. today, April 25, at the Astumbo Gym in Dededo. Testing was provided to residents of Sagan Linhanyan and Lower Astumbo who met the following criteria:

  • Individuals with COVID-19 symptoms

  • Multi-generational families in a household (parents, grandparents, great-grandparents, adult children, their children) with COVID-19 symptoms

The goal of this pilot program is to expand community testing. Government of Guam and private sector nurses took samples from 52 people; 10 were walk-ins and 42 went through the drive-through line. The Guam Public Health Laboratory is processing the samples through a laboratory process called polymerase chain reaction (PCR) to detect traces of the virus that causes COVID-19.
