The Official Veterinary Services received a notification concerning bird mortality and signs consistent with high pathogenicity avian influenza (HPAI) in a backyard in the Buenos Aires province. On the same day, the suspicion was addressed and samples were taken for analysis. The samples were analysed by the Official Laboratory and came back positive for HPAI H5 clade 2.3.4.4. The affected premises are adjacent to bodies of water, so contact with wild birds is presumed

On 14/07/2025, the Official Veterinary Services received a notification concerning bird mortality and signs consistent with high pathogenicity avian influenza (HPAI) in a backyard in the town of Lezama, in the Buenos Aires province. On the same day, the suspicion was addressed and samples were taken for analysis. On 15/07/2025 the samples were analysed by the Official Laboratory and came back positive for HPAI H5 clade 2.3.4.4. The species involved are chickens, peacocks, pheasants and guinea fowl. The affected premises are adjacent to bodies of water, so contact with wild birds is presumed. Stamping out and disposal of all the birds will be carried out, as well as cleaning and disinfection of the premises. We will update the population information in subsequent follow-up reports.

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

By G.M.
{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

By G.M.
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

By G.M.
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.
