Human bird flu cases in California may be undercounted as workers resist testing

Human bird flu cases in California may be undercounted as dairy farm workers avoid testing due in part to economic concerns, according to a labor union and a state expert. Erica Pan, California’s state epidemiologist, acknowledged there is a possibility of an undercount among workers. People who test positive for bird flu must isolate until public health officials have determined they no longer pose a spread risk, according to guidance from the California Department of Public Health.
