Wisconsin Public Radio reported that there will be an increase in bird flu outbreaks in the nation during spring bird migration.
In February, Wisconsin had the second-highest number of birds affected by the highly pathogenic avian influenza among flocks nationwide, according to federal data. Currently, more than 14.3 million birds have been infected in 84 flocks across the country.
Most infections in domestic birds come from exposure to wild birds during spring migration.
Around 200 million birds in more than 2,100 flocks have been affected nationwide since the current strain of avian flu was first detected in 2022. It is the largest outbreak in the nation’s history. More than 11.6 million birds have been infected at around 50 flocks in Wisconsin during the same period.
More than 4.3 million birds in Wisconsin are currently affected.
Bird flu has been detected among nearly 400 wild birds statewide, according to the Wisconsin Department of Natural Resources.
