Bird flu infections undetected


A new study found that a small but not insignificant number of bird flu infections are going undetected among farm workers

Blood samples taken from 115 farm workers in Michigan and Colorado over the summer found evidence of a recent infection in eight individuals — half of whom recalled being ill around the same time the cows were sick. “There is nothing we’ve seen in the new serology data that gives rise to a concern about person-to-person transmission,” Nirav Shah, the agency’s principal deputy director, said at a press conference Thursday morning. In many cases, environmental conditions make PPE almost unusable in dairies — extreme heat waves in California this summer not only resulted in more severe disease among animals, but made wearing masks and goggles too hot, or even dangerous, for workers.
