A cohort of adults in custody housed at the Multnomah County Detention Center underwent testing March 31 after a person who left the facility tested positive for COVID-19.
Corrections Health reported all test results conducted were negative.
Corrections Health and Public Health officials said between 20 to 30 adults in custody who had been in the same module with the one affected person would be in quarantine for the next 14 days.
Because the affected person had no symptoms, had limited movement and was held in a single cell, the risk to the other adults in custody is considered low, officials said.
The Multnomah County Sheriff’s Office is following the County's standard health protocol, which includes keeping a potentially exposed group of people together, monitoring individuals closely for signs of illness and performing testing, as well as continuing ongoing health measures such as providing masks and cleaning spaces frequently.
County Corrections staff continue to offer vaccinations to adults in custody housed at the Detention Center, where at least 90 people have received doses.
