- The United States confirms the first case of rare avians influenza strains H5N9, showing that bird flu virus is mutated among experts found.
- The tension was found in Duck Meat Farm in California in November 2024, and the Animal Health Organization said in the update on Monday. Officials were quarantined and killed all 119,000 birds.
- The farm detects H5N9 with the H5N1 case. The latter strain is associated with the occurrence of bird flu, which has been killed more than 145 million birds since 2022.
Dive Insights:
The H5N9 strain was first identified in China 10 years ago and is considered to be a genetic mix of other strains, including the H5N1, H7N9 and H9N2. Public health experts say that American detection can open the way of “unpredictable new viruses” that can affect both animals and humans.
Angela Rasmussen, a viral scholar of vaccine and epidemic organizations of the Canadian Saskatchewan, said on Twitter X, “This is bad news. “Reconstruction creates an infectious disease.”
According to the Journal of Virology, the rare strain’s N9 genes stems from the lower type H7N9, which was the cause of the occurrence of a number of humans and poultry, with 616 deaths in China.
According to WOAH’s updates, the study of H5N9’s influence is limited, but the signs of California farms included “increased mortality”. The virus caused a low mortality rate in mice, but it is unclear whether this novel H5N9 virus will cause human infections from the birds and become a sub -type.
According to a report released in 2015, it is essential to evaluate the risk of potentially transmitting the risk of the reconstruction virus of this novel to public health.
Rasmussen is considered a “great host” for the reconfirection, which occurs when two or more viruses infect and combine the same host to create new strains. The H5N9 case shows the reconstruction of the bird virus, but if it is combined with the human virus, it can still threaten people.
Rasmussen said, “We need to do more to restrict the opportunity for other viruses to reaffirm.
The US bird flu was an urgent problem in the agricultural industry as the virus jumped from chickens to cows in 2024. In the last 30 days, the virus has affected the virus and has 66 commercial crowds.
Farmers had a group of flocks to prevent more spreads, which caused supply shock in groceries. The price of eggs has increased significantly as the virus has resurrected over the past two months, making it a political flash point in a greater debate on inflation.
