      USDA confirms bird flu in 12th dairy herd, is testing more


      To date, HPAI was confirmed in seven herds in Texas, two in Kansas, and one each in Idaho, Michigan, and New Mexico.

      Published on April 3, 2024

      USDA scientists confirmed the bird flu virus in a dairy herd in Idaho on Tuesday — the 12th herd in five states — with Ohio appearing for the first time on the list of states with “presumptive positive” results that will be double-checked. Meanwhile, officials said a Texas egg farm suffered the largest U.S. outbreak of bird flu in four months.


      Authorities said the risk of transmission to people of the H5N1 strain of highly pathogenic avian influenza (HPAI) remained low. The Texas state Agriculture Department said a “dairy worker who had direct contact with cattle” was being treated for bird flu. The CDC said on Monday the patient’s only symptom was eye redness, consistent with conjunctivitis.

      USDA’s National Veterinary Services Laboratories (NVSL) in Ames, Iowa, conducted the confirmatory tests on the Idaho herd and was conducting the same tests on presumptive positive results from Kansas, New Mexico, Ohio, and Texas, said the Animal and Plant Health Inspection Service.

      “It is important to note that while these samples are from cattle with at least some clinical signs in common with other cattle diagnosed with HPAI, the presence of HPAI should not be considered confirmed until the NVSL analysis is complete,” said the agency.


      To date, HPAI was confirmed in seven herds in Texas, two in Kansas, and one each in Idaho, Michigan, and New Mexico....

        HIGHLY PATHOGENIC AVIAN INFLUENZA (HPAI) AND DAIRY CATTLE

        Main navigation
        On Monday, March 25, 2024, the U.S. Department of Agriculture (USDA), Food and Drug Administration (FDA), and Centers for Disease Control and Prevention (CDC) confirmed the detection of highly pathogenic avian influenza (HPAI) in two dairy herds in Texas and two dairy herds in Kansas that had cattle exhibiting decreased lactation, low appetite, and other symptoms.

        USDA has since confirmed the presence of HPAI other states. For the latest on the HPAI detection in dairy cattle, visit the USDA website.

        Minnesota animal health officials are monitoring this developing situation and are in contact with industry officials. Farm Biosecurity


        Dairy producers are encouraged to consider heightened biosecurity measures such as those described in the Secure Milk Supply Plan.

        The Minnesota Board of Animal Health notes some important biosecurity points:
        • Separate all incoming animals for 21-30 days and screen for signs of disease before allowing them into your herd.
        • Milk imported animals last.
        • Use a Line of Separation and specific access points to restrict staff or visitors to certain areas on the farm.
        • Create a clean/dirty line at barn or parlor entries where staff or visitors can change into barn specific footwear or clothing and clean and disinfect (This point is especially important if staff travel between different locations).
        • Report clinical signs or suspected illnesses to your veterinarian immediately.
        • Know where you source your feed and keep rodents and wildlife away from stored feed. Keep feed covered or contained and clean any feed spills immediately.
        • Provide clean water and keep wildlife away from troughs.
        Milk & Dairy Product Safety


        There continues to be no concern about the safety of the commercial milk supply because products are pasteurized before entering the market. Pasteurization has continually proven to inactivate bacteria and viruses, like influenza, in milk. Pasteurization is required for any milk entering commerce for human consumption.

        Also, dairies are required to send only milk from healthy animals into processing for human consumption. Because milk from impacted animals looks abnormal, it is discarded and does not enter the human food supply.

        People should not prepare or eat uncooked or undercooked food, such as unpasteurized (raw) milk or raw cheeses, from animals with suspected or confirmed HPAI virus infection. Raw milk or unpasteurized dairy products may contain harmful bacteria or viruses and can cause illness.

        The FDA has information on the safety of the milk supply and dairy products. Farm Worker Safety


        The CDC considers the human health risk of H5N1 for the general public low. However, people with close or prolonged, unprotected exposures to infected birds or other animals (including livestock), or to an environment contaminated by infected birds or other animals, are at greater risk of infection. The CDC has interim recommendations for prevention, monitoring, and public health investigations of HPAI viruses.​ https://www.mda.state.mn.us/business...​​​​

          Avian flu confirmed in NM dairy cows in two Curry County herds
          ...

          BY: DANIELLE PROKOP AND AUSTIN FISHER - APRIL 3, 2024 3:20 AM
          ...
          On Tuesday, the state’s top veterinarian said that cows from two separate herds have been confirmed positive for highly pathogenic avian influenza and another herd has “presumptive positives,” meaning suspected positive cases.

          All of the known cases are in Curry County.
          ...
          In a statement, officials said the New Mexico Department of Health is managing the diagnosis, treatment and prevention efforts.
          ...
          “To date, there are no laboratory-confirmed human cases of avian influenza A (H5N1) in New Mexico,” the statement stated.
          ...
          Several other New Mexico dairy herds are undergoing tests after some cows appeared sick, Uhrig said Tuesday. This includes collecting nose swabs, and samples of blood, fecal matter and milk.
          ...
          What caused the outbreak in NM?

          There’s no answers yet, Uhrig said, but investigators are looking to water and feed sources that could have been contaminated by migratory birds.

          “We suspect that there may have been multiple introductions at different locations from wild birds,” Uhrig said. “We’re not really sure why it is now affecting cattle the way that it is. That’s the big question.”

          Uhrig said the method of transmission is still unclear. The transmission may be manually spreading by cows sharing the same feed bucket or touching infected objects.

          “We don’t have an indication that it is directly spreading from one cow to another, but that there may be some sort of mechanical transmission that’s a lateral transmission as well,” Uhrig said. “We can’t rule any of those things out.”

          She said symptoms are not respiratory.

          “In people, that’s what we look at: our nasal swabs, because that’s the route of transmission,” she said. “In cattle, the nasal swabs are not as hot, per se, with the viral load, but the milk does have a pretty heavy viral load.”
          ...

          New Mexico's top veterinarian said that cows from two separate herds have been confirmed positive for highly pathogenic avian influenza.

            Tennessee

            .....Although there have been no detections of HPAI in cattle in Tennessee, producers are reminded to practice strong biosecurity. Cattle owners should minimize animal movements and isolate sick cattle. New animals should be quarantined for a minimum of two weeks before introducing them to an established herd.

            Cattle impacted by HPAI may exhibit low appetite, flu-like symptoms, and thick and discolored milk accompanied by a sharp reduction in milk production. No cattle have died from infection. Older cows may be more likely to be severely impacted than younger cows. If Tennessee dairy producers believe cattle within their herd are showing clinical signs of HPAI, they should report these signs immediately to their local veterinarian, to the State Veterinarian’s Office at 615-837-5120, or the USDA APHIS at 1-866-536-7593.

              What we know about H5N1 bird flu in cows — and the risk to humans
              By Helen Branswell April 3, 2024

              snip

              Is that the full extent of the problem?
              Some experts believe it’s unlikely — if only because people haven’t been looking for bird flu infections in cattle before now. “It could have been infecting dairy cattle a year ago. We just never thought about looking … for it,” said David Swayne, an avian influenza expert who is now a private consultant after having worked for the U.S. Department of Agriculture for nearly 30 years.

              snip

              Are dairy cows spreading the virus to other cows?

              That’s suspected, but it is uncertain at this point. The infected herd in Michigan had received cows recently from Texas.

                Highly Pathogenic Avian Influenza Detected in Ohio Dairy Herd

                April 03, 2024
                A meadow with cows taken from the air with a drone

                The Ohio Department of Agriculture (ODA) received confirmation from the United States Department of Agriculture’s (USDA) National Veterinary Services Laboratory (NVSL) of the detection of highly pathogenic avian influenza (HPAI) in a dairy cattle herd. This is the first case of HPAI in a livestock operation in Ohio.

                The dairy operation in Wood County received cows on March 8, 2024, from a Texas dairy, which later reported a confirmed detection of HPAI. Ohio’s animal health officials were notified when the livestock began showing clinical signs compatible with sick, lactating dairy cows in other states.

                The U.S. Department of Agriculture (USDA), Food and Drug Administration (FDA) and Centers for Disease Control and Prevention (CDC), as well as state veterinary and public health officials, continue to investigate the emerging illness among dairy cows that is causing decreased lactation, low appetite, and other symptoms.

                On Monday, March 25, state animal health officials were notified when federal agencies confirmed the detection of HPAI in dairy herds in Texas and Kansas that had cattle exhibiting these symptoms. USDA’s NVSL has since confirmed the presence of HPAI in additional dairy cattle herds in Idaho, New Mexico, and Michigan.

                Federal and state agencies continue to conduct additional testing from sick animals and in unpasteurized clinical milk samples from sick animals, as well as viral genome sequencing, to assess whether HPAI or another unrelated illness may be underlying any symptoms. Clinically sick dairy cattle from affected herds range from 1% - 20%, with an average of 10% of the milking herd affected. There are no confirmed reports of death loss in dairy cattle directly attributed to these detections. Most sick cows begin recovering within a few days.

                According to the Food and Drug Administration and Centers for Disease and Prevention, there is no concern about the safety of commercially pasteurized dairy products due to both federal animal health requirements and pasteurization and the public health risk associated with HPAI remains low.

                ODA is working with state industry partners and federal agencies to encourage farmers and veterinarians to report cattle illnesses quickly, to monitor potential additional cases and minimize the impact and risk to farmers, farmworkers, consumers, and other animals.

                Producers are urged work with their veterinarian to practice enhanced biosecurity measures and review and limit cattle movements within production systems to avoid disease spread or bringing in cattle from known disease areas or infected herds. More information on biosecurity measures can be found here.

                At this current time, no quarantines or movement restrictions on livestock are being issued by ODA. As officials continue to assess the risks of the emerging disease, and assess epidemiological information, further regulatory control actions may be implemented. If dairy producers in Ohio should see unusual clinical symptoms similar to those described, they are to contact their herd veterinarians.

                For more information on the detections of HPAI in cattle, please visit the U.S. Department of Agriculture’s website.

                  WHO Director-General's opening remarks at the media briefing – 3 April 2024

                  3 April 2024​

                  ...
                  Now to the United States, where the US CDC has confirmed one case of H5N1 avian influenza in a person who works at a commercial dairy farm.

                  The patient did not report any symptoms apart from eye redness, was not hospitalized, and is recovering.

                  Investigations are continuing into how the person was infected, and WHO is in close contact with the US CDC.

                  Any case of H5N1 is concerning because it is highly dangerous to humans, although it has never been shown to be easily transmissible between people.

                  WHO and our partners track influenza viruses globally to monitor the evolution and spread of viruses in both animals and humans.

                    CDC sequencing of H5N1 avian flu samples from patient yields new clinical clues



                    Lisa Schnirring


                    Today at 2:14 p.m.

                    Avian Influenza (Bird Flu) The Centers for Disease Control and Prevention (CDC) last night released a detailed analysis of H5N1 avian flu samples taken from a patient in Texas who was exposed to sick cows, which suggests that the infection might involve the eyes but perhaps not the upper respiratory tract.

                    Also, when CDC scientists compared the human H5N1 samples to viruses from cattle, wild birds, and poultry, they found in the human sample a mutation with known links to host adaptation.

                    Meanwhile, the US Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) announced that highly pathogenic avian flu has been confirmed in a cow herd from Idaho and Ohio agriculture officials said tests have confirmed the virus in a dairy herd that had received cows from Texas.

                    Sequencing shows adaptation change, but not increased transmissibility


                    The CDC detailed its sequencing findings, along with its observations about what those findings might mean for the clinical picture, in a technical update on its website. Scientists saw minor differences between the human specimens and the cattle samples and that the viruses had avian characteristics.

                    However, the human samples had one change—PB2 E67K—that has a known link to virus adaptation to mammalian hosts, seen before in people and animals infected with H5N1, as well as other avian flu viruses. Scientists emphasized that the marker hasn't been linked to transmission and that the results of the analysis doesn't change the CDC's assessment for H5N1 clade 2.3.4.4b viruses that the overall risk to human health remains low.

                    This highlights the value of increased genomic surveillance.

                    Raj Rajnarayanan, MSc, PhD, a computational biologist with the New York Institute of Technology, on X (formerly known as Twitter) said PB2 E67K alone isn't sufficient to enable efficient human to human transmission. "However, this highlights the value of increased genomic surveillance and rapid dissemination of sequence data ASAP."

                    Patient swabs didn't show upper respiratory involvement


                    Also, the CDC detailed what they found during testing of the patient's nasopharyngeal and eye swabs. According to earlier reports, the patient's only symptom was conjunctivitis, a mild symptom seen in some earlier avian flu infections.

                    Testing on the nasopharyngeal sample didn't yield enough RNA for sequencing, but CDC scientists were able to sequence material from the eye swab sample.

                    "Notably, the patient reported only conjunctivitis with no respiratory or other symptoms, which likely resulted in lower viral RNA concentrations detected in the nasopharyngeal sample and is suggestive of a lack of respiratory infection in the patient," the CDC said.

                    Angela Rasmussen, PhD, a virologist with the University of Saskatchewan, on X said that it's good that the patient in Texas didn't become seriously ill, but she said a mild symptom like conjunctivitis may have a down side if mild cases aren't recognized and isolated.

                    We don’t want to give H5N1 the opportunity to adapt to efficient growth in humans. It can be deadly.

                    She warned that undetected cases gives the virus more opportunities to adapt to human hosts, underscoring the importance improved surveillance to identify infections in cows and humans and prevent new ones from occurring, along with reducing exposure risk.

                    "We don’t want to give H5N1 the opportunity to adapt to efficient growth in humans. It can be deadly," Rasmussen said. "To prevent the public health crisis of tomorrow, solve the problem of today."

                    Promising hints for vaccine and antiviral treatments


                    CDC scientists also looked at how well the hemagglutinin (HA) gene from the human specimen aligns with two candidate vaccine virus (CVV) strains it had already prepared for vaccine makers to make a vaccine, if needed. It said the HA from the human virus is very closely to the HA of both CVVs, which suggest that the vaccines would likely protect against the virus.

                    And finally, scientists looked at how well the virus from the human specimen might react to antivirals. The neuraminidase (NA) gene didn't have any resistance markers, which bodes well for the use of neuraminidase inhibitors like oseltamivir. They also examined other gene segments and found no resistance markers to antivirals that target the PA segment (baloxavir) or M2 (amantadine, rimantadine).

                    Confirmation in Idaho and Ohio herds


                    In other developments yesterday, APHIS said testing at the USDA's National Veterinary Services Laboratory (NVSL) in Ames, Iowa, has now confirmed a presumptive positive for highly pathogenic avian influenza in the dairy herd from Idaho. Earlier reports said the facility had received cows from another earlier affected state.

                    Today the Ohio Department of Agriculture announced NVSL has confirmed the virus in a dairy herd in Wood County, the state's first detection. It said the farm, located in the northwestern part of the state, on March 8 had received cows from a Texas far where the virus was later confirmed.

                    It added that the Ohio cows were tested after showing illness signs similar to those in other affected states.

                    APHIS also noted confirmation is also pending on more presumptive positive results from Texas, Kansas, and New Mexico.

                    • APHIS: Recommendations for (HPAI) H5N1 in Livestock For State Animal Health Officials, Accredited Veterinarians and Producers





                      Credit USDA



                      #17,987

                      It's been just over 10 days since we learned that a widespread illness reported in dairy cattle in northern Texas since January was, in fact, HPAI H5N1 (see USDA Statement on HPAI In Dairy Cattle in Texas & Kansas Herds).

                      Although experimental infection of cattle with avian flu had been demonstrated in 2008, cattle were thought to be relatively immune to influenza A, and unlikely hosts for H5N1. As a result, it took several weeks before influenza testing was done.

                      While investigations are ongoing, there are early, worrisome signs that cow-to-cow transmission of the virus may be occurring, and at least 6 states (Texas, Kansas, New Mexico, Michigan, Idaho & Ohio) have reported cases. Additionally, at least 3 dead cats and birds recovered from affected dairy farms have tested positive for the virus.

                      While the risk to the public is still considered low, 4 days ago the state of Texas announced the first (mild) human infection in a dairy worker (see Texas DSHS Health Alert: 1st Human Case of H5N1 Influenza In Texas).


                      Since then we've seen a flurry of technical documents and guidance issued by the USDA and the CDC, including: While it isn't clear how much of a risk all of this poses, we are clearly in uncharted territory. We've no idea how long H5N1 has been circulating in cattle, or how widespread it may be. With the report of HPAI infected goats in Minnesota in late March, the possibility of spillover into other livestock - including swine - must be considered.

                      Testing takes time, and uses (finite) laboratory resources, and right now the emphasis is on testing symptomatic dairy cows . While it would certainly be helpful if we could cast a wider net, the logistics are daunting.We've neither the time, nor the lab capacity, to test more than a tiny percentage of U.S. livestock. And even if we could, it would only provide a snapshot of a brief point in time. There is also a strong possibility that HPAI H5 has quietly made inroads into cattle or pigs in other countries around the globe.

                      While we will certainly learn more over time, the emphasis right now is on limiting the damage, even if we can't see the full extent of the threat. And that means increasing farm biosecurity, minimizing the movement of cattle, improving the safety of farm workers (PPEs, vaccines, etc.), and increased surveillance of both livestock and farm workers.

                      While far from ideal, it may be our only option at this time. To that end, APHIS (the Animal and Plant Health Inspection Service of the USDA) published a 4-page set of guidance this week for State Health Officials, Veterinarians, and Producers.

                      I've reproduced the first page below, follow the link to read it in its entirety. I'll have a postscript after you return.



                      There is much debate over just how big of a deal all of this is. With the dearth of information at present, it is fair to say no one really knows. The jump to cattle - and apparent cow-to-cow transmission - is a clear escalation of the threat, but it isn't necessarily a prelude to a pandemic.

                      Yes, it does provide the virus with more opportunities to adapt to mammalian species, and a better chance of spilling back into humans than - say - from infected sea lions or skunks in the wild.

                      But it isn't nearly as alarming as finding it spreading in pigs (or mink), which already carry a wide array of influenza A viruses and offer much better potential for reassortment.







                      That, of course, could still happen. Hopefully, increased testing of swine is in the works, particularly for exhibition pigs (see EID Journal: Shortening Duration of Swine Exhibitions to Reduce Risk for Zoonotic Transmission of Influenza A Virus), which have sparked small outbreaks of swine variant virus infections in the past.

                      While some of the `worst-case scenarios' being bandied about online, or in the tabloids, are probably overblown (see Revisiting the H5N1 CFR (Case Fatality Rate) Debate), anything over a 1% fatality rate would be devastating.

                      Whether it is caused by HPAI H5, or some other novel subtype (e.g. H5N6, H3N8, H9N2, etc.) - another influenza pandemic is inevitable. And if it turns out to be severe, we'd better be bettered prepared to deal with it than we were with COVID.

                          • CDC to doctors: Look out for bird flu infections among dairy farm workers

                            By Helen Branswell
                            CYNTHIA GOLDSMITH/CDC The Centers for Disease Control and Prevention urged medical practitioners on Friday to be on the lookout for people who might have contracted H5N1 bird flu from cows. The agency also urged state health departments to rapidly assess any suspected human cases, and recommended that dairy farms with confirmed or suspected outbreaks require workers to use personal protective equipment.

                            The recommendations were outlined in a health alert network advisory, or HAN in CDC parlance. The advisory is in response to the outbreak of H5N1 avian influenza in at least 16 dairy herds in six states across the country, which has led to at least one human infection so far.​….
