As swine flu cases continue to be discovered, Washington’s schools superintendent says he’s in the process of reviewing their emergency health plan. Dave Sextro says he met with school nurses and is sending letters home to parents explaining what the plan is. Sextro says students and their parents are encouraged to practice frequent hand washing. He says parents should keep their students home if they are feeling ill. There have been no cases of the H1N1 virus discovered in Washington County.
