A Fulton County charter school will be sanitized because a student tested positive for swine flu, school officials said. "As a precaution, we will be sanitizing our entire facility over the weekend," Amana Academy principal Amaris Obregon said in a statement posted Friday on the school's Web site. The Alpharetta school reported Friday that a kindergartner was discovered to have had a case of the H1N1 virus earlier in the week.
