Government health officials report 40 people in the United States are now infected with swine flu. While none of those cases are in Alabama, State Health Officer Don Williamson says it’s only a matter of time before there is a case here. Swine flu concerns did hamper the return of some Trussville City Schools band students from a weekend trip to Mexico, where more than 100 people have died due to swine flu. Health officials determined the students didn’t pose a special risk. Don Williamson is monitoring the swine flu situation and spoke with WBHM’s Andrew Yeager.
