Swine Flu (H1N1) downgraded by US Health and Human Services Secretary

U.S. health officials are no longer recommending that schools close for two weeks over suspected cases of the A/H1N1 flu virus.

Hundreds of schools around the country had followed the guidance in the past week. At a press briefing Tuesday, Health and Human Services Secretary Kathleen Sebelius said the virus had turned out to be milder than initially feared. The number of confirmed cases in the U.S. is now over 400, with hundreds more probable cases.
