A Norovirus outbreak has sickened approximately 123 people who ate at a Longview restaurant last week, health officials said Friday.  All of the people who became ill ate at Parker’s Restaurant in Longview, said Don Strick, Cowlitz County Health spokesman.  The outbreak appears to be winding down, however, health officials expect reports of more cases.  People who became ill should stay home for three days following virus symptoms and are advised to drink plenty of liquids.
