The CDC has confirmed detection of a new bird flu variant H5N9 in dairy cattle across 12 Texas farms, with two farmworkers testing positive for mild infections, raising concerns about potential pandemic risk.

Current Situation

The variant shows genetic mutations that improve its ability to bind to human respiratory cells, though human-to-human transmission has not been documented. Both infected workers recovered fully with antiviral treatment.

Response

The USDA has imposed quarantines on affected farms and is testing cattle nationwide. The CDC has activated its pandemic preparedness protocols as a precaution.
