Outbreak Escalation: Bird Flu Sweeps US and Beyond

Bird flu continues to make national and global headlines this week, with outbreaks and concerns spreading across both the US and international borders. In the United States, the situation remains particularly tense as newly confirmed outbreaks are reported in several states. The US Department of Agriculture confirmed five new avian flu outbreaks in the last 24 hours across duck and turkey farms in Indiana and Michigan, as well as a backyard flock in Washington. Over 113,000 birds were affected in one Michigan turkey farm alone, and nearly 21,000 birds were hit at a duck farm in Indiana, according to CIDRAP and Michigan’s Department of Agriculture updates.

Washington State currently faces the second-highest number of bird flu cases nationwide. Nearly 2 million cases were reported there in October alone, with large commercial facilities hit especially hard. State officials warn that these numbers are closely tied to migratory bird patterns and have triggered increased vigilance throughout the region, as reported by Axios. Since the outbreak began in 2022, more than 4 million birds have been affected across 21 counties in Washington.

Complicating containment and response efforts, the ongoing US federal government shutdown, now over 35 days in length, has led to fewer resources for monitoring and tracking the virus, as noted by The Humane Society’s blog. With many federal workers furloughed and key coordination slowed, public health officials acknowledge the heightened risk of more rapid spread and further mass culling of poultry. Over 3.5 million birds have already been culled across the US in recent weeks to contain the outbreaks.

Globally, the situation remains serious. According to The Conversation and CEPI reports, H5N1 bird flu has caused massive die-offs not only in poultry but also among wild birds and even some mammal species in North America and Europe. In Canada, the highly pathogenic H5Nx subtype has killed close to 15 million birds, including endangered species. There is growing concern about silent or asymptomatic human infections. CDC researchers indicate that while there has not yet been sustained human-to-human transmission, sporadic human cases have been reported in Mexico, Bangladesh, and Cambodia, some resulting in severe illness or death. Scientists warn of the potential for the virus to mutate or recombine with seasonal flu strains, increasing the risk of a pandemic.

On the vaccine front, the Coalition for Epidemic Preparedness Innovations has pledged additional funding to accelerate development of more universal bird flu vaccines, using newer and faster production platforms.

At this time, the CDC maintains that public health risk from bird flu in the US remains low, but continues to urge vigilance, strong farm biosecurity, and thorough cooking of poultry products. Meanwhile, scientists stress the importance of continued public reporting of both domestic and wild bird illnesses as a critical part of surveillance and prevention.
