Nearly 97m domesticated birds in the US have been affected by highly pathogenic influenza, exacerbated by human activities and shared resources like vehicles and equipment.
Reports from Michigan highlight the role of workers, cows, vehicles, and equipment in spreading the virus between farms, with genomic analyses indicating human-facilitated transmission.
One-third of dairy employees in the US with outbreaks work in other livestock farms, emphasizing the interconnectedness and potential spread of bird flu through shared resources.
Shared vehicles and equipment among farms, coupled with inadequate cleaning practices, contribute significantly to the cross-contamination and spread of the H5N1 virus.
Biosecurity practices are crucial in preventing further outbreaks, with experts emphasizing the need for stringent measures to contain the spread of bird flu.
