              Influenza activity is increasing in Iowa.
              This includes three cases of a novel influenza strain in children in Webster and Hamilton counties. This virus, an influenza A/H3N2 recombinant virus, has also been detected in Pennsylvania, Maine, and Indiana in recent months and contains components of human, avian, H1N1, and swine influenza. All spread in Iowa has been human to human, and spread appears to be limited; no further cases have been identified in the last week.
