Several inmates quarantined in a dormitory at the Utah State Prison in Draper because of H1N1 swine flu worries do not have the virus, according to the Department of Corrections.

The quarantine was lifted Monday afternoon. It began June 17 when several men showed flu-like symptoms.

"The logistics of a prison environment, with offenders living in such close quarters, require that we be vigilant in protecting the health of offenders and Corrections staff," Corrections Executive Director Tom Patterson said in a news release. "This experience provided a good drill in responding to threats of infectious conditions inside the facilities."

Tests are out for one other Utah State Prison inmate, who arrived at the Draper facility with flulike symptoms. An inmate at the Central Utah Correctional Facility in Gunnison also does not have the H1N1 virus.
