A powerful avian flu strain has made its way through a Utah mink farm, and it could potentially spread to and between humans next. Many experts are concerned about the U.S. government’s lack of action to prevent the spread.
This strain of bird flu is “so virulent that if a single chicken tests positive, the U.S. government requires farmers to kill the whole flock,” said ProPublica. The virus, however, has spread uncontrolled through the mink farm for more than two months.
The outbreak is particularly concerning because “mink have lungs and airways that on a cellular level are remarkably similar to those of people,” said ProPublica. The mammals have previously contracted Covid-19 and spread it to humans, and bird flu could follow the same trajectory.
Despite the risk of a major public health crisis, there’s “just not a lot of options out there other than kind of sitting and waiting and seeing what happens,” said Utah State Veterinarian Amanda Price to ProPublica. Mink are “bred in captivity and raised on farms, occupying a regulatory gray area between wildlife and agriculture,” said The Salt Lake Tribune.
There’s no acute pandemic threat at the moment. The risk is “greatest among people who have exposure to sick animals,” said Jennifer Nuzzo, an epidemiology professor at Brown University, to The Guardian. “If that’s not you, I think you can take this off your worry list,” but that “does not abdicate the government of its responsibility to try to prevent a pandemic.”
