A new study lends weight to fears that more livestock workers have gotten the bird flu than has been reported. “I am very confident there are more people being infected than we know about,” said Gregory Gray, the infectious disease researcher at UTMB who led the study, posted online Wednesday and under review to be published in a leading infectious disease journal. “Largely, that’s because our surveillance has been so poor.” This news was also reported in Ars Technica, Oregon Capital Chronicle, News Tribune and many other outlets.
