What the Experts Say"},"content":{"rendered":"\n

Why are US health officials growing concerned about bird flu? What mutations are scientists finding in recent human cases? Will there be a bird flu pandemic in 2025?<\/p>\n\n\n\n

Bird flu has spread rapidly through US dairy farms and poultry operations, infecting nearly 1,000 dairy herds and causing mostly mild illness in dozens of exposed workers. While bird flu hasn\u2019t been transmitted between humans yet, health officials are concerned that it could be. <\/p>\n\n\n\n

Here’s a look at the situation and the studies.<\/p>\n\n\n\n\n\n\n\n

Bird Flu Is on the Rise<\/h2>\n\n\n\n

Last week a person in Louisiana died from bird flu<\/a>\u2014the first such death in the US\u2014after genetic analysis revealed mutations help the virus more easily infect humans. The death intensifies efforts to contain an outbreak that’s spread through nearly 1,000 dairy herds and infected dozens of people across the country. This is leaving Americans wondering if there will be a bird flu pandemic in 2025.<\/p>\n\n\n\n

H5N1 Background<\/strong><\/h3>\n\n\n\n

The deadly bird flu (H5N1) virus, which resurfaced in Europe in 2020<\/a>, has now spread across every continent except Australia<\/a>. H5N1 has infected an unprecedented range of species, moving beyond wild birds and poultry to affect various mammals, including seals, dolphins, cats, and dogs.<\/p>\n\n\n\n

The outbreak took a dramatic turn in March 2024 when the US detected the first H5N1 cases in dairy cows<\/a>. By April, the virus had spread through multiple herds across several states, with FDA testing revealing bird flu traces in 20% of US commercial milk samples<\/a>.<\/p>\n\n\n\n

A Look at the Outbreak<\/strong><\/h3>\n\n\n\n

The H5N1 bird flu outbreak has expanded dramatically in the US, infecting 917 dairy cow herds across 16 states<\/a>, as of January 7, 2025. The virus has severely impacted the poultry industry, with the Department of Agriculture documenting infections affecting over 25 billion birds in 50 commercial and 38 backyard flocks<\/a>.<\/p>\n\n\n\n

Human infections have increased steadily since April 2024<\/a>, with the Centers for Disease Control and Prevention (CDC) confirming 64 cases nationwide<\/a>. The majority stemmed from human contact with infected dairy cows (39 cases) or poultry (22 cases), while two cases had no clear source. Though most people experienced mild symptoms like eye inflammation and respiratory issues, the virus recently proved lethal in Louisiana<\/a>.\u00a0<\/p>\n\n\n\n

Lessons From E. Coli Outbreaks
<\/strong>
In his book Fast Food Nation<\/a>,<\/em> Eric Schlosser discusses how E. coli can spread among cattle. While the situation is different, it gives us some insight into how diseases spread among farm animals.

E. coli in beef has likely been present in American cattle herds for decades. But until the rise of industrial-scale, centralized meatpacking driven by the demands of the fast food industry, its spread was fairly limited. The disease gets its start in the vast feedlots of today\u2019s slaughterhouses.

These facilities are marked by appalling sanitary conditions, where the cattle are packed into close quarters, given little exercise, and splash around in pools of manure. This creates ideal conditions for bacteria to grow and make the animals sick. This is exacerbated by what the cattle are now increasingly being fed: the rendered remains of dead sheep and other cattle, as well as dead dogs and cats purchased from animal shelters. Natural herbivores, cows\u2019 stomachs are not designed to eat other animals. Forcing them to do so is not only inhumane and cruel, but also facilitates the growth of deadly parasites in their bodies that are then passed on to the humans who eventually consume their meat.

Things get even worse after the animals are slaughtered. When workers improperly pull out the stomach and intestines of the cattle by hand, they often spill the contents of the digestive system all over the slaughterhouse floor. With the industry\u2019s relentless focus on speed and scale, much of this finds its way into the meat that\u2019s sold to consumers. Similarly, these workers are rarely instructed in how to clean and disinfect the knives they use to cut cattle carcasses.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

H5N1 Genetic Analysis<\/strong><\/h3>\n\n\n\n

Recent genetic analyses of H5N1 virus samples have found mutations that could strengthen the virus’s ability to infect humans. <\/p>\n\n\n\n
