“Thijs Kuiken, an avian influenza researcher at Erasmus Medical Center, says the “very sparse” information released by the U.S. government has international implications, too. State and federal animal health authorities have “abundant information … that [has] not been made public, but would be informative for health professionals and scientists” in the United States and abroad, he says, “to be able to better assess the outbreak and take measures, both for animal health and for human health.” He notes that even the new sequences released by USDA do not include locations of the samples or the date they were taken. The release appears to include data from only 39 cows.”
