SHOOT: Good to see such a rapid response.
Officials at the Centers for Disease Control and Prevention (CDC) acknowledged on Friday that "concern has grown" since the first reports of a novel swine flu infecting patients in Texas and California emerged late March.
Of the 14 samples of suspected swine flu from Mexico that the CDC has tested so far, half are positive for swine flu, a form of influenza that normally infects pigs and can be transmitted to people. (See pictures of the world's most polluted places.) The CDC is working with the World Health Organization to keep track of any additional cases to determine whether and when a warning of a pandemic would be warranted. In preparation for such a scenario, the CDC has created a seed stock of a vaccine against the swine flu, which could be pushed into production should the number of cases jump significantly. The CDC did not specify what the threshold for vaccine production would be. |
