#USA, #Connecticut: Highly Pathogenic Avian #Influenza #H5N1 Detected in New London County #Backyard #Poultry Flock

(HARTFORD, CT) – Connecticut Department of Agriculture (CT DoAg) advises that Highly Pathogenic Avian Influenza (HPAI) H5N1, or bird flu, was confirmed in a backyard flock located in New London County on Wednesday, January 15, 2025.

The backyard flock, consisting of chickens, ducks, and peacocks, were family pets, not commercial poultry, and had close contact with wild waterfowl in a nearby pond.

Samples were sent to the Connecticut Veterinary Medical Diagnostic Laboratory (CVMDL) for testing. The results from CVMDL were then confirmed by the United States Department of Agriculture National Veterinary Services Laboratory (NVSL) in Ames, Iowa. H5N1 is highly contagious among domestic poultry, and at this time there is no effective treatment or approved vaccine for the virus in poultry. The infected flock has been depopulated to prevent spread of the disease.

“Collaboration between state and federal partners is essential in preventing the spread of highly pathogenic avian influenza in poultry and safeguarding the health of our farmworkers,” said Agriculture Commissioner Bryan P. Hurlburt. “Through a united approach we are able to swiftly identify and respond to protect our food supply and ensure the health of our communities.”

All poultry owners and producers are advised to enhance biosecurity protocols to protect their backyard and commercial poultry flocks against H5N1.

“Biosecurity is the best defense for a flock owner to protect their birds from disease,” said State Veterinarian Dr. Thamus Morgan, DVM, MPH, DACVPM. “This should be top of mind for commercial and backyard hobby owners – we must all work together – to reduce the risk.”

Biosecurity Tips

-- Poultry biosecurity materials and checklists can be found on the USDA’s Defend the Flock website. Best practices include:

- Keep wild birds and rodents out of poultry houses and coops.

- Don’t let poultry have contact with migratory waterfowl or other wild birds.

- Wash hands and boots before and after entering the poultry area.

- Buy birds from reputable sources to receive heathy birds.

- Restrict traffic onto and off your property.

- Have a written biosecurity plan in place.

Signs of H5N1 infection include sudden increase in bird deaths, sneezing, coughing, nasal discharge, watery or green diarrhea, lack of energy, poor appetite, drop in egg production, swelling around the eyes, neck, and head, and purple discoloration of wattles, combs, and legs.

Flock owners are encouraged to report anything unusual, especially sick or dead birds, to CT DoAg at 860-713-2505 or ctstate.vet@ct.gov or the USDA at 866-536-7593.

#Neuroinvasive #Oropouche virus in a patient with #HIV from extra-Amazonian #Brazil

{Excerpt} A novel reassortant Oropouche virus (OROV) lineage (with medium [M], large [L], and small [S] RNA segments : M1L2S2) has driven Brazil's largest and most geographically widespread OROV epidemic , expanding beyond the endemic Amazon basin to establish local transmission across multiple Brazilian states and other previously unaffected Latin American countries . The rapid spread of this lineage underscores its evolutionary potential and reinforces its significance as a public health threat .1 Similar to chikungunya and Zika viruses, expanding arboviruses can exhibit unexpected clinical and epidemiological shifts , including vertical transmissions , neuroinvasive effects, and potentially fatal outcomes.2–4 Although OROV typically causes self-limited febrile illness, accumulating clinical and experimental evidence suggests neurotropic potential .5 This Correspondence describes the first confirmed case of neuroinvasive OROV infection caused by the emergent M1L2S2 lineage in ext...

Stability of #influenza viruses in the #milk of #cows and #sheep

Abstract In late 2023, H5N1 high pathogenicity avian influenza (HPAIV) started circulating in dairy cattle in the USA . High viral titres were detected in milk from infected cows , raising concerns about onwards human infections . Although pasteurisation was shown to effectively inactivate influenza viruses in milk, unpasteurised milk still poses a risk of infection, both from occupational exposure in dairies and from the consumption of raw milk. We therefore assessed how long influenza viruses could remain infectious for in milk without heat inactivation. We examined the stability of a panel of influenza viruses in milk , including a contemporary H5N1 HPAIV and a variety of other influenza A and D viruses. We incubated viruses in cows' milk under laboratory conditions : at room temperature to simulate exposure in dairies and at 4°C to simulate exposure to refrigerated raw milk. Following an isolated report of H5N1 viral RNA being detected in milk from a sheep in the UK , we also c...

#Evidence of #Viremia in Dairy #Cows Naturally Infected with #Influenza A {#H5N1} Virus, #California, #USA

Abstract We confirmed influenza A virus (IAV) by PCR in serum from 18 cows on 3 affected dairy farms in California, USA . Our findings indicate the presence of viremia and might help explain IAV transmission dynamics and shedding patterns in cows. An understanding of those dynamics could enable development of IAV mitigation strategies.
