The Food and Drug Administration (FDA) has green-lighted a test that can quickly determine whether a person is infected with deadly avian flu.
The FDA yesterday approved the AVantage A/H5N1 Flu Test, made by Sunnyvale, Calif.-based Arbor Vita Corp. The nose or throat swab can detect the infection in less than 40 minutes, the agency said; previous diagnostic tests took up to four hours.
"This test is an important tool to help quickly identify emerging influenza A/H5N1 infections and reduce exposure to large populations," Daniel Schultz, director of the FDA's Center for Devices and Radiological Health, said in a statement. "The clearance of this test represents a major step toward protecting the public from the threat of pandemic flu."

We've known since January that most of the flu circulating this season is resistant to Tamiflu, an antiviral drug typically used against the infection. What remained a mystery was whether the resistant flu strain made people sicker than forms that respond to the treatment — and why the resistant strain surged this year, a worry for public health officials who stockpiled Tamiflu in the event of a flu pandemic stoked by avian influenza.
A study published today in the Journal of the American Medical Association indicates that Tamiflu-resistant flu does not make people any more or less sick. But researchers say they're still in dark as to why Tamiflu-resistant infections are on the rise. A whopping 98 percent of this year's circulating H1N1 flu strains are immune to Tamiflu, compared with only 12 percent during the 2007-2008 flu season.
