A recent investigation found “strong evidence” that sick dairy animals were the source of the H5N1 virus that a farm worker in Texas tested positive for.
In recent years, the virus has affected other people as well, some of whom have even died, but all of them contracted it from birds.
Concern over American officials’ inability to stop the virus’s spread is mounting.
Nine states and thirty-six herds have so far tested positive. However, milk testing indicates that the virus may have spread far further.
The longer it proliferates unchecked in a domesticated mammal, the higher the likelihood that it may adapt to a new species and be transferred to humans in close proximity.
