H5N1 Flu

Environmental surveillance has emerged as a pivotal strategy for early detection of pathogens that pose threats to humans (1) but has not been utilized for zoonotic agents. In Asia, live-bird markets (LBMs) are key human-animal interfaces for zoonotic virus transmission (2). Traditional sampling str …

The epidemic of high pathogenicity avian influenza (HPAI) H5N1 in the United Kingdom and Northern Europe from 2021 to 2023 has dwarfed all previous incursions. This fact has driven the need to review biosecurity behaviours and perceptions of virus incursions on commercial poultry farms. This study u …

The evolution and adaptation of highly pathogenic avian influenza (HPAI) viruses pose ongoing challenges for animal and public health. We investigated the pathogenic characteristics of the newly emerged H5N1/2022 and H5N8/2022 of clade 2.3.4.4b compared to the previously circulating H5N1/2016 of cla …

Infections with H5N1, a type of pathogenic avian influenza (HPAI) virus, are spreading among livestock farmers, particularly among dairy cows in the United States. Until now, HPAI/H5N1 has rarely infected humans, but transmission from H5N1-infected dairy cows to dairy workers has been reported. Addi …

H5N1 subtype influenza A viruses represent a long-standing pandemic concern. Owing to their global occurrence in poultry, humans are routinely exposed to these viruses, and hundreds of human cases have been documented worldwide since 2003. The relevant viral lineages are not static, however, and hav …

Cats in two states tested positive after eating raw food from Wild Coast Raw, which issued voluntary recall

State officials warn that the risk for animals is high and urge residents to take precautions to limit the spread of the virus.

The Centre for Food Safety (CFS) of the Food and Environmental Hygiene Department announced on Thursday that it has directed the industry to temporarily halt the import of poultry meat and products fr...

With the COVID-19 pandemic still fresh in the minds of many U.S. citizens, concerns over the government’s ability to contain emerging health threats persist. The ongoing struggle to control the H5N1 bird flu outbreak has raised alarms, particularly as the virus has begun spreading beyond poultry to cows and even humans. While the likelihood of a pandemic remains low, if one does occur, it could be as disruptive as 2020, if not worse.

Restrictions on agency communication hinder US response to H5N1, Congress warns.

By Leisa Boley Hellwarth Force majeure, translated from French, means “superior forces.” This is a l

The 2 patients exposed to poultry had severe infections, with H5N1 confirmed only from lower respiratory tract samples.

Pre-existing immunity against seasonal H1N1 flu might help explain why most reported human cases of H5N1 bird flu in the U.S. have not resulted in lethal outcomes.

Two new humans cases in Ohio and Wyoming were hospitalized.

After the cats tested positive for the avian flu, the health authorities in the state had quarantined the owners and monitored them.

Researchers found that environmental sampling in live-bird markets detects 70–90% of poultry viruses, often outperforming traditional swab methods, and identified 50 additional viruses, some from non-avian sources.

An East County house cat who died last month represents the first case of bird flu found in a cat countywide, local health officials said Wednesday.

Avian influenza viruses, particularly the H5 and H7 subtypes, can cause widespread outbreaks in birds and pose a significant zoonotic risk due to their potential to mutate and develop the ability for human-to-human transmission. Researchers from the University of Muenster described the preclinical efficacy of zapnometinib, a selective MEK1/2 inhibitor, against H5N1 clade 2.3.4.4b.

After the cats tested positive for the avian flu, the health authorities in the state had quarantined the owners and monitored them.

The Illinois state veterinarian says the state is increasing its efforts to monitor dairy cattle for H5N1 avian flu. Dr. Mark Ernst tells Brownfield, “The Illinois Department of Public Health is beginning their initiation of milk testing at processors, and so that should give us an idea as to whether or not we have any […]

Previous infections with seasonal H1N1 flu may boost immunity and reduce the severity of H5N1 bird flu, according to a study.

Donald Trump’s Health and Human Services (HHS) Secretary, Measles-dismisser, nepo-baby, bear cub-dumper, and vaccine skeptic, Robert F. Kennedy, Jr., was one of the president’s more questionable nominations. This is a significant achievement in itself when compared with other dangerously unsuitable

The situation is not good

Two people in the US have been admitted to hospital with H5N1 avian flu, adding to concerns over the growing number of infections in cattle, poultry, wildlife, and humans worldwide. As of 24 February, a woman in Wyoming remains in hospital while a man in Ohio has been discharged. Both patients had severe “respiratory and non-respiratory symptoms,” the CDC said in its weekly flu report.1 “This shows that H5N1 can be very severe, and we should not assume that it will always be mild,” Angela Rasmussen, a virologist at the Vaccine and Infectious Disease Organisation at the University of Saskatchewan, told the Guardian .2 The hospital admissions bring the total number of patients with severe cases of H5N1 in the US to four since the first was reported in …
