        Issue: Free standing Long Term Care Facility experiencing an outbreak of Norovirus with an attack rate of 12.5%. Facility has mix cases of neuro-rehab, pallaitive, sub-acute, and respite care. The outbreak was confined in the neuro-rehab unit.One staff member on that unit was experiencing an acute gastroenteritis on February 15,2007. 2 of the staff family members has onset of acute gastroenteritis on February 14,2007. This staff member came to work on 2/15/07 and called in sick on 2/16/07 and off on 2/17-18. He came back to work on 2/19/07 without symptoms of gastroenteritis.On evening of 2/20/07 three residents on the unit were experiencing nausea,vomiting and diarrhea and in the morning of 2/21/07, there were 5 additional cases with the same symptoms. All stool and vomitus specimens were send to internal laboratory to check for: salmonella, Clostridium difficile, VRE, and shigella.Additional specimens were send to Public Health for norovirus testing. In the afternoon of same day results came back from both laboratories, three specimens tested positive for Norovirus RNA group 2 detected by PCR were reported by the Public Health. The Infection Control Team made a decision that the unit will be close for new admission and implemented the facility outbreak protocol and followed the CDC Norovirus guidelines.
        Project: Prevent and control transmission of Norovirus Outbreak to other units of the facility.
        Results: There were no report of acute gastroenteritis from other units of the facility. No additional staff members affected. Outbreak contained within one week. The unit was open for new admission after 72 hours from the last reported case.
        Lessons Learned: 1. Outbreak policy has been effective in controlling transmission of disease. 2.
