#USA, #Massachusetts: State Officials Suspect HPAI Outbreak Impacting Geese and Other Wildlife

PLYMOUTH — State environmental and health officials are informing the public that Highly Pathogenic Avian Influenza (HPAI), which very rarely infects humans, is suspected to be the cause of over 60 deceased Canada geese, swans, and other birds in Plymouth. 

The Division of Fisheries and Wildlife (MassWildlife), the Massachusetts Department of Agricultural Resources (MDAR), and the Massachusetts Department of Public Health (DPH) are advising the public to refrain from handling birds or other animals that are dead or appear sick.

Reporting wild birds: The public should report observations of sick or deceased birds if 5 or more birds are found at a single location using this simple form at mass.gov/reportbirds.

Reporting domestic birds: The public should report sick or dead poultry or other domestic birds by calling MDAR’s Division of Animal Health at (617) 626-1795.

Handling birds and other wildlife: The public should strictly avoid handling any sick or dead birds or other animals. Report sightings as indicated above or call the local Animal Control Officer.

Keeping pets safe: Pets should always be kept away from wildlife. Cats are highly susceptible to HPAI and may die from an infection. Cat owners in affected areas should keep their pets indoors to prevent them from being exposed to infected wildlife.

Hunting geese: While eating wild game meat is generally considered safe, licensed hunters can minimize risk from wildlife diseases by following best practices when handling and processing game.  

The recent outbreak at Billington Sea in Plymouth has impacted over 60 Canada geese, swans, and ducks

Smaller outbreaks of suspected HPAI impacting fewer than 15 geese at each location have been reported in recent weeks in other parts of the state

Officials responded quickly and are collecting, testing, and safely disposing of dead birds. 

Prompt reporting of sick and dead birds by the public will expedite testing and diagnosis in cooperation with state and federal partners who have been monitoring HPAI for several years.

Both wild and domesticated birds can become infected with HPAI. Raptors, waterfowl and other aquatic birds are most at risk for infection, although any bird species should be considered susceptible. Birds may be infected with HPAI without showing any signs of illness. Wild mammals, especially those that scavenge on birds such as foxes, can also become infected.

Humans are rarely infected with avian influenza viruses. Humans that have prolonged close contact with sick or dead birds infected with HPAI are the most at risk of becoming infected. People with questions about the public health impact of HPAI can visit DPH’s Avian influenza webpage or call the Division of Epidemiology (available 24/7) at 617-983-6800.

#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.
