Bird Flu in the US: Current Insights and Uncertainties

The United States is currently experiencing a significant outbreak of bird flu, with genetic traces of the virus found in 1 in 5 commercial milk samples. The question on everyone’s mind is: does this virus pose a threat to humans?

Understanding Avian Influenza

Highly pathogenic avian influenza (HPAI) is a viral illness that primarily affects wild and domestic birds. However, the virus can sometimes jump to other animals, including dairy cows and, in rare cases, humans.

“Bird flu, or avian influenza, infects more than 100 species of wild birds, especially migratory waterfowl,” said Carl Abraham, an assistant professor of medicine at the New York Institute of Technology. “In birds, it is highly contagious and causes a respiratory illness that can be either highly pathogenic or low pathogenic.”

Pathogenicity and Transmission

Pathogenicity Defined

Pathogenicity refers to how severely an infected animal becomes ill. The highly pathogenic form of avian influenza, responsible for the current outbreak, can spread beyond the airways and lungs, infecting multiple organs and often leading to death in birds within 48 hours.

Transmission to Mammals

Over the last decade, there has been an increase in bird flu cases among mammals. Infection in mammals usually occurs after the animal consumes an infected bird.

“In 2024, the first reports of avian influenza (H5N1 strain) infected U.S. domesticated cattle, possibly being transmitted cow-to-cow,” Abraham said. “This is now a multistate outbreak, although the number of infected cattle in each state is small, and the illness is marked by transient reductions in milk production.”

Impact on Dairy Cows and Milk Safety

Despite the relatively small number of infected cows, the U.S. Food and Drug Administration has found genetic traces of the virus in 1 in 5 commercial milk samples tested. The pasteurization process ensures these virus fragments cannot cause an infection, but there are concerns about the risks associated with unpasteurized “raw milk.”

A recent report from the U.S. Centers for Disease Control and Prevention warned that unpasteurized milk poses a significant risk for potential cross-species infections. The study highlighted the risks to domestic cats, which have developed fatal infections after consuming unpasteurized milk from affected cows.

Domestic Cats and Bird Flu

“Our findings support those of previous work that has shown domestic cats can be highly susceptible to HPAI A (H5N1) virus,” said Eric Burrough, a professor of veterinary medicine at Iowa State University. “Cats with outdoor access should be monitored to avoid potential exposure to and consumption of dead wild birds.”

Can Humans Catch Bird Flu?

“It is rare for avian influenza to infect humans,” Abraham noted.  “Two cases have been reported in the U.S., both in persons with significant exposure to infected mammals—most recently this year in a cattle worker in Texas who had conjunctivitis [pink eye] as the only symptom.  Therefore, the risk of illness to humans is extremely low.”

Individuals who own birds that come into contact with wild birds and cattle farmers are at the highest risk of coming into contact with bird flu, though the risk of illness remains negligible.

The Evolution of Viruses and Potential Risks

As observed in 2020, viruses can evolve rapidly.

“Influenza has a complicated replication cycle within multiple species,” Abraham explained.  “This frequently causes the genes of different strains within a single host to mix, commonly referred to as recombination events.

Most recombination events result in influenza viruses that are not able to replicate or replicate less efficiently.  However, rare recombination events may increase illness severity, increase transmission, or even, as we are seeing with cattle this year, infection of new species.

A recombination event can give avian influenza the ability to infect humans.  If the same virus caused human-to-human transmission, it could have pandemic potential. Again, this would be a rare event, but it is possible.”

Preparing for the Future

While no significant threat to humans has been identified, studying viral transmission patterns can help predict and prevent future pandemics. “The new information gained as we study viral outbreaks helps us to prepare for the next pandemic [not an ‘if,’ but ‘when’ scenario],” Abraham added. “Responses to outbreaks based on scientific evidence are most likely to result in the best public health outcome. What we learn today may save us tomorrow. That which we ignore puts us at risk. Stay safe.”

Conclusion

The current bird flu outbreak in the U.S. has raised concerns about cross-species infections and the potential risks to humans. While the risk of human infection remains low, ongoing research and monitoring are essential to prevent future pandemics.

FAQs

1. How is bird flu transmitted to mammals?

Bird flu can be transmitted to mammals primarily when they consume infected birds. The virus can spread among mammals, as seen in the recent cases involving cattle.

2. Can pasteurized milk carry the bird flu virus?

No, pasteurized milk cannot carry the bird flu virus capable of causing infection. The pasteurization process destroys the virus fragments found in milk samples.

3. Are domestic cats at risk of bird flu?

Yes, domestic cats can be at risk of bird flu, especially if they consume infected birds or unpasteurized milk from infected cows. Monitoring and controlling their exposure to these sources is crucial.

4. What are the symptoms of bird flu in humans?

In the rare cases where humans have been infected, symptoms have included conjunctivitis (pink eye). The overall risk of illness in humans is extremely low.

5. How can we prepare for future pandemics?

Studying viral transmission patterns and recombination events helps us understand how viruses evolve and spread. This knowledge is vital for developing strategies to prevent and mitigate future pandemics.
