Could 16, 2024 – A number of U.S. companies are working to include the current chicken flu outbreak amongst cattle to stop 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 employees and most people secure. 

Fingers crossed, the chicken flu shall be contained and peter out. Or the outbreak may 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 may change in a approach that makes it simpler to contaminate and unfold amongst folks. If this occurs, the worst-case state of affairs could possibly be a brand new influenza pandemic. 

With so many unknowns, WebMD introduced collectively consultants from 4 federal companies to speak prevention, monitoring, and what the “what ifs” of chicken flu may appear to be.

Communication with the general public “about what we all know, what we don’t know, and methods you and your loved ones can keep secure is a precedence for us at CDC,” mentioned Nirav D. Shah, MD, JD, the CDC’s principal deputy director. “We on the federal stage are responding, and we would like the general public to be following alongside.”

Individuals 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 knowledge, Shah mentioned throughout “Chicken Flu 2024 – What You Must Know,” an internet 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 people stays low. 

The retail milk provide is secure, though consuming uncooked or unpasteurized milk just isn’t really helpful. “Whereas business milk provide is secure, we strongly advise towards consuming uncooked milk,” mentioned Donald A. Prater, DVM, appearing director for the FDA’s Middle for Meals Security and Utilized Diet.

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 effectively.

For years, federal inspectors have bought and examined meat at retail shops, mentioned Eric Deeble, DVM, USDA deputy assistant secretary for the Workplace of Congressional Relations. To this point, H5N1, the virus behind chicken flu, has not been detected in beef. 

The USDA took testing a step additional and lately 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 greater kills the virus if it ever turns into essential.

The federal authorities now requires all cattle be examined and be freed from chicken flu virus earlier than crossing any state traces. The federal government can also 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 employees. 

Vaccination Not Advisable Now

Federal scientists know sufficient about H5N1 virus to create vaccines towards 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,” mentioned 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 folks, “we’ve got the constructing blocks to provide a vaccine,” Boucher added. 

An occasion attendee requested if the seasonal flu shot gives any safety. “Sadly, the flu shot you bought final yr 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.”

Therapies Stockpiled and Prepared

Antiviral medicines, which if given early in the middle of chicken flu an infection may shorten the severity or period of sickness, can be found now, Shah mentioned. The dairy farmer who was contaminated with chicken flu earlier this yr responded to oseltamivir (Tamiflu) remedy, for instance. 

In terms of chicken flu signs, the truth that the one contaminated individual reported thus far this yr developed pink eye, also called conjunctivitis, is attention-grabbing, Shah mentioned. Officers would have anticipated to see extra typical seasonal flu signs, he added. 

“Influenza just isn’t a brand new virus,” Boucher mentioned. “With this pressure of influenza, we aren’t seeing any genetic markers related to resistance to antivirals. Meaning the antivirals we take for seasonal influenza would even be obtainable 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 want them,” he added.

“Influenza is an enemy we all know effectively,” Boucher mentioned. That’s the reason “we’ve got antivirals able to go now and plenty of sorts of PPE.”

Science in Motion

The feds intend to remain on the case. They’ll proceed to watch emergency division visits, lab check 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 mentioned. 

Shah added, “As in any outbreak, that is an evolving scenario and issues can change. What you might be seeing now’s science in motion.”
