CDC, WebMD give update on current bird flu outbreak: ‘Be alert, not alarmed’
As bird flu continues to spread among cattle in the U.S., WebMD and the Centers for Disease Control and Prevention (CDC) joined forces on Thursday to present a live-streamed briefing on the status of the outbreak.
The presentation, called “WebMD and CDC Presents, 2024 Bird Flu: What You Need to Know,” was moderated by Neha Pathak, M.D., chief physician editor for WebMD in Atlanta, Georgia.
The first reports of sick dairy cows came to the USDA in early March, according to Eric Deeble, deputy assistant secretary for the Office of Congressional Relations at the United States Department of Agriculture (USDA) in Washington, D.C.
AMID BIRD FLU SPREAD, EXPERTS REVEAL IF IT’S SAFE TO DRINK MILK
Testing revealed that the cows had contracted H5N1, more commonly known as avian influenza, or bird flu.
“Any new disease of cattle is a great concern to us,” Deeble said during the briefing.
“The H5N1 in cattle is a relatively mild disease. They generally recover after supportive care” within two to three weeks, he said.
“Their milk volume returns to normal, and they appear healthy and continue to feed as they did before they became sick.”
“Any new disease of cattle is a great concern to us.”
So far, the USDA has detected H5N1 in 49 dairy herds in nine states, Deeble stated.
“To put that into perspective, that’s around 1% of dairy farms in the affected states and about 1/10th of 1% nationally,” he said.
On April 29, a federal order from the USDA took effect, limiting the movement of lactating dairy cattle in an effort to monitor and compile H5N1 test results.

“Under this order, dairy farmers are required to test their cows before moving them across state lines so that we know those cows are H5N1-free and don’t pose a risk to any new herd,” Deeble said.
The order also requires that any test results that detect the presence of H5N1 are reported to USDA labs.
No current food risk, experts say
Deeble assured those tuning in on Thursday that there is no risk with consuming milk and meat.
“I can say without reservation that our commercial milk and meat supplies are safe,” he said. “At no time were animals that are sick from H5N1 or any other animal disease permitted to enter into our food supply.”
He added, “USDA has never detected H5N1 in meat sold at retail.”
Tests have confirmed that cooking meat to an internal temperature of 155 or above is sufficient to eliminate all traces of the virus, Deeble noted.
For milk, the pasteurization process ensures it is safe to drink, he said.
“Our milk is cleared to a high temperature for a brief period of time, inactivating H5N1, as well as other bacteria and viruses that could make someone sick,” he said.
Risk of transmission to humans
The overall risk to the public from bird flu is low, according to Dr. Nirav D. Shah, M.D., principal deputy director of the CDC in Atlanta.
“That is in part because it’s rare for people to get infected with bird flu viruses — but it has happened,” he said during the briefing.
“If and when it does happen, it’s most often through direct unprotected contact with infected animals — for example, not wearing gloves, face masks or eye protection.”
COULD A BIRD FLU PANDEMIC SPREAD TO HUMANS? HERE’S WHAT YOU NEED TO KNOW
In April, the CDC reported one human case of bird flu in a dairy worker in Texas, Shah said.
“This person’s only symptom was eye redness, or conjunctivitis,” he said. “After testing positive, this person was provided [with] an antiviral medicine and thankfully made a full recovery. There have been no new or additional human cases since this individual in Texas.”
Other symptoms to watch for include cough, fever, muscle aches and fatigue, according to Shah.
Although the overall risk to humans is low, the CDC is taking “aggressive steps” to make sure Americans stay well and informed, Shah said.
“Right now, one of our top areas of focus is around farm worker safety and protection — specifically making sure that workers have access to personal protective equipment … like gloves, goggles or face masks, which can help reduce their risk of exposure if they happen to be working around affected cows.”
MAINE WILDLIFE AUTHORITIES FIND 6 DEAD WILD DUCKS THAT TESTED POSITIVE FOR BIRD FLU
The CDC is also working with local health departments to ensure that sick farmers are tested for bird flu and to monitor their status.
“In addition to that, scientists in our laboratories here at CDC are looking closely at the bird flu viruses to see if there are any changes in their DNA that might tell us if these viruses are able to spread more easily to people, between people, and, importantly, whether they might be causing more serious illness,” Shah added.
Although the risk to the public “remains low” currently, the doctor offered guidance for certain groups that may be at a higher risk.
“If you happen to work around animals, whether it’s chickens, whether it’s cattle, or whether it’s pigs, and you develop signs and symptoms that might otherwise be the flu, it’s important to make sure you call a health care provider and have a conversation with them.”
Not another COVID, experts say
The current situation with bird flu is different from the early days of COVID-19, Shah said during the briefing.
“We are in a much different place because of over two decades of investment in planning and preparing for things like influenza,” he said.
CDC WARNS OF INVASIVE BACTERIAL OUTBREAK AMID SPIKE IN CASES AND FATALITY RATES: ‘RARE BUT SEVERE’
“As a result of that extensive planning and preparedness, there are medicines in place.”
If those medications are given early, they can reduce the severity and duration of illness, as was the case with the farmer in Texas, Shah noted.
“This is just one of many ways in which … influenza and bird flu differs from what many of us remember from four years ago,” he added.
Vaccines and prevention
The traditional influenza vaccine doesn’t provide much protection against avian flu, the experts noted.
“Even though they are … basically the same virus, they differ just enough to where the flu shot — which we hope everyone gets — doesn’t do a great job at protecting you,” said Shah.
“It might do a little bit of work, but it’s not enough to take you to the bank.”
David Boucher, PhD, director of Infectious Diseases Preparedness and Response at ASPR in Washington, D.C., spoke during the Thursday briefing about the potential need for a bird flu vaccine.
“We’re not at a spot where vaccination is recommended for anyone,” he said.
Through the National Influenza Vaccine Program, the ASPR works with health partners to identify influenza viruses that are “just a little bit different from the things that we’ve seen in the past,” Boucher said.
WITH WHOOPING COUGH CASES ON THE RISE, DO YOU NEED A BOOSTER VACCINE?
For a novel virus, the team develops “building blocks” of a vaccine, he noted.
“The good news here is that this system has worked the way we hoped it would, and we have an initial supply of the building blocks we would need if we needed vaccines for the [H5N1] virus,” he said.
In that scenario, Boucher said, the ASPR could partner with manufacturers of seasonal influenza vaccines for “large-scale” production.
Boucher also emphasized the importance of personal protective equipment (PPE) — such as gloves, goggles, face shields and N95 masks — for agricultural workers who may be close to infected animals.

To monitor potential spread, the CDC is on the lookout for an increase in emergency department visits or laboratory tests that might signal a “cluster of cases,” Shah said.
“We’re also more recently looking at wastewater to see if there are changes there,” he said.
People can stay up to date on the latest bird flu developments from the CDC, the USDA, the FDA and other trusted sources of information, Shah added.
“We should be alert, not alarmed.”

Deadly virus samples went missing from lab in ‘major biosecurity breach,’ say authorities
Hundreds of deadly virus samples are missing from a laboratory in Australia, the Queensland government announced on Monday.
The government has instructed Queensland Health — Australia’s public health department — to launch an investigation into what’s being described as a “major historical breach of biosecurity protocols,” according to the online media statement.
It was reported that 323 vials of multiple infectious viruses — including Hendra virus, Lyssavirus and Hantavirus — went missing from Queensland’s Public Health Virology Laboratory in August 2023.
‘DISEASE X’ HAS KILLED DOZENS IN THE CONGO — HERE’S WHAT TO KNOW ABOUT THE MYSTERY ILLNESS
Hendra is a zoonotic (animal-to-human) virus that has only been found in Australia.
Hantavirus is a family of viruses that can lead to serious illness and death, according to the Centers for Disease Control and Prevention, while Lyssavirus is a group of viruses that can cause rabies.
The lab where the samples went missing provides “diagnostic services, surveillance and research for viruses and mosquito and tick-borne pathogens of medical importance,” the release stated.
It is not known whether the infectious samples were stolen or destroyed, the statement said, and there is “no evidence of risk to the community.”
The government has launched a “Part 9 investigation.”
DEADLY OUTBREAK OF MARBURG, OR ‘BLEEDING EYE VIRUS,’ LEADS TO TRAVEL ADVISORY
“With such a serious breach of biosecurity protocols and infectious virus samples potentially missing, Queensland Health must investigate what occurred and how to prevent it from happening again,” Minister Timothy Nicholls said in the release.
“The Part 9 investigation will ensure nothing has been overlooked in responding to this incident and examine the current policies and procedures in operation today at the laboratory.”
“This investigation will also consider regulatory compliance and staff conduct.”
Nicholls added that Queensland Health has taken “proactive measures,” including retraining staff on required regulations and conducting audits to ensure correct storage of materials.
Sam Scarpino, PhD, director of AI and life sciences at Northeastern University in Boston, confirmed that the situation in Australia amounts to a “critical biosecurity lapse.”
“Given the limited ability for any of these pathogens to transmit from person to person, the risk of an epidemic is very low.”
“The pathogens reported missing are all high-consequence and could pose a threat to the public,” he told Fox News Digital.
The three pathogens can have very high fatality rates in humans, Scarpino said, but they do not transmit readily from person to person.
“Some hantaviruses have case fatality rates of up to 15%, or over 100 times more lethal than COVID-19, while others are more similar to COVID-19 in terms of severity,” he said.
There is also a high risk to animals and livestock from all three pathogens, he added.
FIRST KNOWN CASE OF RARE MPOX STRAIN CONFIRMED IN UNITED STATES
The Lyssavirus family contains the rabies virus, which is almost universally fatal in humans if they do not receive treatment in time, the expert noted.
“Given the limited ability for any of these pathogens to transmit from person to person, the risk of an epidemic is very low,” Scarpino said.
“However, Hendra virus — along with certain members of the Hantavirus and Lyssavirus family — can be very severe in humans and animals.”
Chief Health Officer Dr. John Gerrard reiterated in the media statement that there is no evidence of public risk.
“It’s important to note that virus samples would degrade very rapidly outside a low temperature freezer and become non-infectious,” he said.
“It’s very unlikely that samples were discarded in general waste, as this would be completely outside routine laboratory practice.”
There have been no human cases of Hendra or Lyssavirus in Queensland over the past five years, Gerrard noted, and no confirmed Hantavirus infections “ever in Australia.”

Despite the low risk, Scarpino said, “It’s important to understand where these samples ended up, to confirm that there is no longer a risk of exposure.”
“While I applaud the Australian government for taking this seriously, it’s unacceptable that it took over a year for news of the breach to be made public.”
“The pathogens reported missing are all high-consequence.”
There have been similarly high-profile biosecurity lapses in the U.S., Scarpino noted.
“It’s clear that we need quite a bit more investment and transparency related to pathogen biosecurity,” he added.

CDC warns of deadly drug 100 times more potent than fentanyl, overdoses spike in past year
Fentanyl has made headlines for driving overdose deaths, but the Centers for Disease Control and Prevention (CDC) is warning of the rise of an even deadlier drug.
Last year, nearly 70% of all U.S. overdose deaths were attributed to illegally manufactured fentanyls (IMFs). One of those was carfentanil, an altered version of fentanyl that is said to be 100 times more potent, the CDC warned in a Dec. 5 alert.
Deaths from carfentanil rose by more than 700% in the past year, according to the same source — there were 29 deadly overdoses between January and June 2023, and 238 in that same time frame in 2024.
RED FOOD DYE COULD SOON BE BANNED AS FDA REVIEWS PETITION: ‘SCARY STUFF’
This data came from the CDC’s State Unintentional Drug Overdose Reporting System (SUDORS).
The numbers could actually be higher, as the 2024 data is preliminary and not all overdose deaths have been reported, the agency noted.
Since an outbreak of carfentanil-linked deaths in 2016 and 2016, the drug had “largely disappeared” until this recent reemergence, the CDC noted.
Based on the increase in fatal overdoses, the CDC is calling for “rigorous monitoring” of carfentanil and other opioids more potent than fentanyl.
DRUG OVERDOSES HAVE REACHED RECORD HIGH, PER LATEST CDC REPORT: ‘GRIM STATISTICS’
As with other illicit drugs, its “high profitability” likely drives its prevalence, according to Dr. Chris Tuell, clinical director of addiction services at the University of Cincinnati College of Medicine.
“Very small amounts can produce thousands of doses,” he told Fox News Digital.
“Synthetic opioids like carfentanil are relatively easy to manufacture in illicit labs,” Tuell went on. “Since the drug is a synthetic, it is easier to produce — unlike heroin, which is dependent on a plant like opium.”
Why is carfentanil so dangerous?
Carfentanil is 10,000 more times more potent than morphine and 100 times more potent than fentanyl, Tuell confirmed.
“Even a small amount can be fatal, as it can cause respiratory failure,” he said.
One of the major concerns with carfentanil and fentanyl is that they are frequently mixed with other drugs, such as benzodiazepines, cocaine and opioids, which can lead to accidental overdoses, according to Tuell.
“Carfentanil can also resemble cocaine and heroin, so it blends right in with the other drugs,” he warned.
“Even a small amount can be fatal, as it can cause respiratory failure.”
“Even a tiny amount can increase the potency of a drug mixture, leading to a stronger and longer-lasting high.”
Carfentanil often appeals to drug users who have a high tolerance to opioids because they seek a stronger substance, “making the drug attractive despite the risk,” Tuell noted.
How is the drug administered?
Carfentanil can be injected and is frequently mixed with other opioids or heroin, Tuell said. In a powder form, it can be inhaled.
“Inhaling the drug can be quickly risky because it can enter the bloodstream, resulting in an overdose,” Tuell warned. “This can happen intentionally or accidentally, as the drug can become easily airborne.”
Carfentanil can sometimes be in the form of “pressed pills” that resemble prescription medications, the expert said.
“Carfentanil can be lethal at the 2-milligram range depending on the route of administration,” he cautioned.
What parents should know
“Children are now the generation of artificial intelligence and deepfakes, as illicit drugs are posing like regular prescription medications,” Tuell cautioned.
To help protect kids from the dangers of illicit drugs, the expert emphasized the importance of open communication and education.

“Educate your child about the dangers and risks of drug use, including synthetic opioids like carfentanil,” he advised.
Parents should provide monitoring and supervision of their children, be aware of their social circles and limit unsupervised online activities, Tuell recommended.
“I also believe it is important that parents realize that 84% of individuals with a substance use disorder also have a co-occurring mental health issue,” he added.
“Seeking out mental health services for your child could help address the underlying issues that may have led to a substance use disorder.”

The CDC called for specific efforts in preventing deaths from illegally manufactured fentanyls, “such as maintaining and improving distribution of risk reduction tools, increasing access to and retention of treatment for substance use disorders, and preventing drug use initiation.”

Read the Letter From Nobel Laureates Urging That Mr. Kennedy Not be Confirmed
December 9th, 2024
To Members of the United States Senate:
We, the undersigned Nobel Laureates, are writing to ask you to
oppose the confirmation of Robert F. Kennedy, Jr. as Secretary of the
Department of Health and Human Services (DHHS).
The proposal to place Mr. Kennedy in charge of the federal agencies
responsible for protecting the health of American citizens and for
conducting the medical research that benefits our country and the
rest of humanity has been widely criticized on multiple grounds. In
addition to his lack of credentials or relevant experience in
medicine, science, public health, or administration, Mr. Kennedy has
been an opponent of many health-protecting and life-saving
vaccines, such as those that prevent measles and polio; a critic of
the well-established positive effects of fluoridation of drinking
water; a promoter of conspiracy theories about remarkably
successful treatments for AIDS and other diseases; and a belligerent
critic of respected agencies (especially the Food and Drug
Administration, the Centers for Disease Control, and the National
Institutes of Health). The leader of DHHS should continue to nurture
and improve— not threaten—these important and highly respected
institutions and their employees.
In view of his record, placing Mr. Kennedy in charge of DHHS would
put the public’s health in jeopardy and undermine America’s global
leadership in the health sciences, in both the public and commercial
sectors.
