Federal officials have asked the National Science Advisory Board for Biosecurity (NSABB) “to review the state of the science looking at human transmission of deadly bird flu, says panel chief Paul Keim of Northern Arizona University,” USA Today reports. “In December, the NSABB asked the journals, Science and Nature, to withhold details of studies that showed how to make the flu strain transmissible between ferrets, the closest mammal model for human-to-human transmission of the bug,” the newspaper notes. “‘We are now involved in a broader review,’ Keim says. … ‘This research is valuable, but saying this is just “basic” research ignores that influenza is a very special pathogen,’ Keim adds,” according to the newspaper (Vergano, 1/10).
