Might 16, 2024 – A number of U.S. businesses are working to comprise the current hen flu outbreak amongst cattle to forestall additional unfold to people (past one case reported in early April) and use what we discovered earlier than, throughout, and after the COVID-19 pandemic to maintain farm staff and most of the people protected.
Fingers crossed, the hen flu will likely be contained and peter out. Or the outbreak might proceed to unfold amongst dairy cattle and different animals, threatening the well being and livelihoods of farmers and others who work with livestock.
Or the virus might change in a method that makes it simpler to contaminate and unfold amongst individuals. If this occurs, the worst-case state of affairs might be a brand new influenza pandemic.
With so many unknowns, WebMD introduced collectively consultants from 4 federal businesses to speak prevention, monitoring, and what the “what ifs” of hen flu would possibly appear like.
Communication with the general public “about what we all know, what we don’t know, and methods you and your loved ones can keep protected is a precedence for us at CDC,” stated Nirav D. Shah, MD, JD, the CDC’s principal deputy director. “We on the federal degree are responding, and we wish the general public to be following alongside.”
Folks ought to seek the advice of the web sites for the CDC, FDA, U.S. Division of Agriculture (USDA), and the Administration for Strategic Preparedness and Response (ASPR) for updates.
It’s important to not solely keep knowledgeable, however to hunt trusted sources of data, Shah stated throughout “Chook Flu 2024 – What You Must Know,” a web-based briefing collectively sponsored by the CDC and WebMD.
An ‘Experimental Hamburger’
If one take-home message emerged from the occasion, it was that the risk to most of the people stays low.
The retail milk provide is protected, though consuming uncooked or unpasteurized milk is just not really helpful. “Whereas industrial milk provide is protected, we strongly advise in opposition to consuming uncooked milk,” stated Donald A. Prater, DVM, performing director for the FDA’s Middle for Meals Security and Utilized Vitamin.

As for different meals, totally cooked eggs are much less dangerous than uncooked eggs, and the nation’s beef provide stays freed from the virus as properly.
For years, federal inspectors have bought and examined meat at retail shops, stated Eric Deeble, DVM, USDA deputy assistant secretary for the Workplace of Congressional Relations. To date, H5N1, the virus behind hen flu, has not been detected in beef.
The USDA took testing a step additional and not too long ago cooked floor beef from dairy cows of their lab. Utilizing what Deeble described as an “experimental hamburger,” the company confirmed cooking beef to 165 F or larger kills the virus if it ever turns into vital.
The federal authorities now requires all cattle be examined and be freed from hen flu virus earlier than crossing any state strains. The federal government can be reimbursing farmers for veterinary care and lack of enterprise associated to the outbreak, and provide private protecting tools (PPE) like gloves, masks, and face shields to staff.
Vaccination Not Really useful Now
Federal scientists know sufficient about H5N1 virus to create vaccines in opposition to it rapidly if the necessity arises. It’s extra about planning forward at this level. “Vaccines are usually not a part of our response proper now,” stated David Boucher, PhD, director of infectious illnesses preparedness and response on the Administration for Strategic Preparedness and Response.
If the virus adjustments and turns into a much bigger risk to individuals, “we’ve the constructing blocks to provide a vaccine,” Boucher added.
An occasion attendee requested if the seasonal flu shot provides any safety. “Sadly, the flu shot you bought final 12 months doesn’t present nice safety from the avian flu,” Shah responded. “It’d perform a little bit … however that’s the vaccine for seasonal flu. That is one thing extra novel.”
Remedies Stockpiled and Prepared
Antiviral drugs, which if given early in the middle of hen flu an infection might shorten the severity or period of sickness, can be found now, Shah stated. The dairy farmer who was contaminated with hen flu earlier this 12 months responded to oseltamivir (Tamiflu) therapy, for instance.

Relating to hen flu signs, the truth that the one contaminated individual reported up to now this 12 months developed pink eye, often known as conjunctivitis, is fascinating, Shah stated. Officers would have anticipated to see extra typical seasonal flu signs, he added.
“Influenza is just not a brand new virus,” Boucher stated. “With this pressure of influenza, we aren’t seeing any genetic markers related to resistance to antivirals. Which means the antivirals we take for seasonal influenza would even be accessible if wanted to deal with H5N1.”
ASPR has stockpiled Tamiflu and three different antivirals. “We do have tens of hundreds of thousands of programs that may be distributed across the nation if we’d like them,” he added.
“Influenza is an enemy we all know properly,” Boucher stated. That’s the reason “we’ve antivirals able to go now and plenty of kinds of PPE.”
Science in Motion
The feds intend to remain on the case. They are going to proceed to observe emergency division visits, lab take a look at orders, and wastewater samples for any adjustments suggesting a human pandemic danger is rising.
“Whereas we’ve discovered an incredible deal, there are nonetheless many issues we do not know,” Deeble stated.
Shah added, “As in any outbreak, that is an evolving scenario and issues can change. What you might be seeing now could be science in motion.”
