H1N1 patients may be infectious 10+ days

USA Today reports two studies presented at ICAAC "by researchers in Canada and Singapore found that roughly one in five patients continue shedding the new H1N1 virus, or swine flu, with one study suggesting that patients may still shed virus despite treatment with Tamiflu.

The research suggests that the current prevention guidelines for "self-isolation" may not be long enough, says one investigator, Gaston De Serres of the National Institute of Public Health in Canada. Guidelines from the U.S. Centers for Disease Control and Prevention indicate that it's safe for flu patients to mingle with others 24 hours after fever abates.

With seasonal flu, people are not believed to be infectious after a week, De Serres says. The new studies indicate that some patients may still be infectious for a longer period after they fell ill with flu."
