TUCSON, AZ - Seven clusters of Norovirus found in assisted-living homes for seniors have authorities in southern Arizona warning the public about the sometimes fatal flu-like illness.
The Pima County Health Department is warning the public to be vigilant about washing their hands, keeping common areas disinfected and staying home if they're sick.
Extra caution should be used around the elderly and children, who are more susceptible to Norovirus.
The department is investigating seven clusters of the virus found in assisted-living facilities in the area.
They say Norovirus is not uncommon in such homes but that it's rare to see so many different clusters at the same time.
The department says that Norovirus is highly contagious and can cause nausea, vomiting, diarrhea and stomach cramps. The elderly, infants and people with other medical conditions can suffer more serious symptoms, including death.
