Chinese researchers reported the first ever clinically documented case of resistance to the antiviral medication Tamiflu in patients infected with the H7N9 bird flu.
Chinese officials have closed poultry markets and ordered a mass slaughter of birds in Shanghai amid an outbreak of a type of avian flu that has not been seen in humans.
University of Tokyo scientist Yoshihiro Kawaoka is making the case for unfettered access to studies in which researchers made a lethal bird flu virus even deadlier by taking it airborne. To those determined to find it, the recipe is already available, he warns, and the mutation could occur outside the laboratory at any moment. All hands to the urgent task of developing a vaccine, then.
