MedPage Today 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 the University of Texas Medical Branch 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.”
As bird flu cases go underreported, health officials risk being slow to notice if the virus were to become more contagious. A large surge of infections outside of farmworker communities would trigger the government’s flu surveillance system, but by then it might be too late to contain.
“We need to figure out what we can do to stop this thing,” Gray said. “It is not just going away.”
The Centers for Disease Control and Prevention bases decisions on its surveillance. For example, the agency has bird flu vaccines on hand but has decided against offering them to farmworkers, citing a low number of cases.
