The Nation : Influenza Cases on Rise

The number of influenza cases in the United States is increasing, federal health officials said, with most states reporting a type of the respiratory disease that primarily attacks children. The national Centers for Disease Control said in Atlanta that through last Monday, 16 states reported flu activity. Twelve of those states listed cases caused by the B-type influenza virus, which has mostly struck children. Ten states had flu cases resulting from the same virus that was responsible for epidemics in the 1950s and 1960s.
