As the norovirus season starts with higher than expected reported outbreaks, now is a good time for infection prevention staff to review infection prevention and control measures, as outlined in the CDPHE guidance document “Summary Guidelines for Investigation and Management of Norovirus Outbreaks in Healthcare and Residential Facilities,” located at:
In preparation for what may be a busy season, CDPH&E recommends the following:
? Review and enforce employee sick leave policies
? Place ill residents on contact precautions quickly after onset of GI symptom (such as diarrhea or vomiting)
? Report outbreaks to your local public health agency or CDPHE as soon as an outbreak is suspected (even before laboratory confirmation of norovirus).
If you have questions or concerns, please contact your local public health agency, or the CDPHE
