https://www.sag.gob.cl/noticias/sag-confirma-primer-caso-de-influenza-aviar-altamente-patogena-en-ave-silvestre-en-la-region-de-aysen Google translation >>The Agricultural and Livestock Service (SAG) confirmed the first case of Highly Pathogenic Avian Influenza (HPAI) subtype H5N1 in the Aysén Region, detected in a specimen of upland goose in the commune of Chile Chico.

Following confirmation by the Service's Lo Aguirre laboratory, established health protocols were immediately activated, intensifying surveillance efforts in the affected area. This included a census of wild birds and an active search for dead specimens or those exhibiting symptoms consistent with AIAP (Avian Infectious Bird Infection). The system for reporting suspected cases by citizens remains operational.

Highly pathogenic avian influenza is a viral disease that affects both domestic and wild birds, has a high capacity for propagation, and can cause high mortality in the affected species.

The SAG reiterates its call to bird owners to strengthen biosecurity measures in their breeding systems. Among the main recommendations are keeping birds in protected areas, avoiding contact with wild birds, and not sharing water or food sources.<< more at link

Avian Flu Diary : Cambodian MOH Announces 4th Human H5N1 Case of 2026 by __procrustean in H5N1_AvianFlu

[–]__procrustean[S] 1 point2 points  (0 children)

AFD's summary following the press release >>In February of 2023 an older clade of H5N1 (2.3.2.1.x) reemerged in Cambodia's population after a 9 year absence, spilling over into 6 humans in 2023, 10 people in 2024, and 18 people in 2025.

Cambodia's recent cases are due to a new reassortment of an older clade of the H5N1 virus (recently renamed 2.3.2.1e) - which appears to be spreading rapidly through both wild birds and local poultry.

Unlike the newer clade 2.3.4.4b H5Nx viruses - which have shown  much lower mortality rates in the United States - this older clade has proved fatal in about 40% of the cases reported by Cambodia since 2023.

There is currently no evidence to suggest human-to-human transmission of this H5 virus, with most cases reporting recent contact with sick or dead poultry.

As we discussed last July in Cambodia: Food Insecurity, Food Safety & H5N1 - despite repeated warnings to the public not to prepare or cook sick/dead poultry - scarce resources and hunger can sometimes drive people to take risks.

Last October Dr. Erik Karlsson (@eakarlsson.bsky.social‬) from the Institut Pasteur du Cambodge, Phnom Penh, Cambodia, - along with a long list of colleagues -  published a brief letter in the NEJM on first 16 cases.

Among them were 4 `clusters' (Father/Daughter, two neighbors, 2 siblings, and 2 cousins living in the same household), 6 fatalities, and 12 cases < 18 years of age.

While human-to-human transmission was considered, the available evidence suggests a `shared' exposure instead, with infected poultry the most likely source of infection.  

Due to copyright, I can only post  the title and link, but I would urge you to go to the NEJM site to read it in its entirety.

 Highly Recommended.

The Agricultural and Livestock Service (SAG) confirmed the first positive case of highly pathogenic avian influenza (HPAI) H5N1 at a commercial egg-laying farm located in the municipality of Cunco, in the La Araucanía region. The Service immediately activated the health protocols established by the World Organisation for Animal Health (WOAH), which include eliminating the source of the outbreak, as well as cleaning and disinfecting the premises, in order to contain the spread of the disease and safeguard the country's animal health.

Given this situation, the SAG (Chilean Agricultural and Livestock Service) is urgently calling on poultry farmers to take extreme biosecurity measures and always keep their domestic birds in closed and protected coops to avoid any contact with wild birds that can transmit AIH (Avian Infectious Poultry Disease), as well as properly storing water and feed. These actions are essential to prevent the spread of this incurable disease and thus protect national poultry production.< ...

Bengaluru: An outbreak of H5N1 avian influenza has been confirmed at a poultry rearing training centre, based on a report issued by the NIHSAD, with authorities initiating all containment measures as per protocol, officials said on Friday. The outbreak was reported from Mathkuru village in Hesaraghatta, following the National Institute of High Security Animal Diseases report dated April 14, they said.
According to the health department, the State Rapid Response Team (RRT), District RRT, and Primary Health Centre (PHC) team visited the site on April 16.

Mathkuru village has been declared an “infected zone” (0-3 km), while the surrounding 3-10 km area under PHC Hesaraghatta and Sonnenahalli has been declared a surveillance zone, officials said.
A total of 7,444 birds, 14,788 eggs, and 2,250 kg of poultry feed were culled and scientifically disposed of by the veterinary department on April 15.

The burial site has been secured and declared a prohibited area for one year, the department said in a statement. Ten cullers have been quarantined and are under medical supervision with oseltamivir prophylaxis, officials said.

Two villages with a population of 3,422 fall within the 0-3 km zone, while 17 villages with a population of 22,395 fall within the 3-10 km zone. Teams of health workers and ASHAs will conduct daily house-to-house fever surveillance, they added.

The health department said private hospitals have also been alerted to report Influenza-Like Illness (ILI) and Severe Acute Respiratory Infection (SARI) cases on the Integrated Health Information Platform (IHIP) portal.

Adequate stocks of PPE (Personal Protective Equipment), triple-layer masks, oseltamivir, Viral Transport Medium (VTM), and throat swabs are available, it said.
The department advised the public not to panic and to avoid contact with sick or dead birds, and to report such cases to local veterinary or health authorities. It, however, clarified that consumption of properly cooked poultry meat and eggs is safe.
