My son-in-law, daughter and both grand kids had something about 2 weeks ago. My daughter who is high school teacher said something similar to the flu was going through the Moore school system like crazy and not to come by as it was contagious. They were all sick as dogs for several days vomiting and diarrhea.
My aunt, who is a tutor at a grade school, got something in Dec and was sick of weeks. I read the other day the flu shot this year is not very effective against one of the three strains of flu. If you sneeze around me, I leave the area with a bye see you later.
