U.S. Health authorities have several concerns about the new Swine flu as it spreads. Reuters reported:
The new influenza strain circulating around most of the United States is putting a worrying number of young adults and children into the hospital and hitting more schools than usual, U.S. health officials said on Monday
CDC officials say around 100,000 people are likely infected with the new flu strain in the United States and Schuchat said the 5,123 confirmed and probable cases and six deaths in the United States were "the tip of the iceberg."
From zero to 100,000 in a month? So much for containment. It's now at the anti-viral and inoculation stage.
