Health officials say swine flu activity is picking up, with 37 states now reporting widespread cases.

Officials with the federal Centers for Disease Control and Prevention reported Friday that the count is up from 27 states the previous week. The figures suggest a leveling off of flu activity the previous week may have been short-lived.

Meanwhile, CDC officials say states have ordered 3.6 million doses of swine flu vaccine for a campaign that started this week.
