H5N1 Flu

These results suggest that both rLC16m8-mcl2.2 HA and rDIs-mcl2.2 HA are effective in preventing HPAI H5N1 virus infection, and rDIs-mcl2.2 HA is a promising vaccine candidate against H5 HA-subtype viruses.

The ongoing circulation of highly pathogenic avian influenza (HPAI) A (H5N1) viruses, particularly clade 2.3.4.4b strains, poses a significant threat to animal and public health. Recent outbreaks in cattle highlight concerns about cross-species transmission and zoonotic spillover. Here, we found tha …

Background/Objective: Highly pathogenic (HP) H5Nx and low-pathogenicity (LP) H9N2 avian influenza viruses (AIVs) pose global threats to the poultry industry and public health, highlighting the critical need for a dual-protective vaccine. Methods: In this study, we generated a model PR8 …

Avian influenza has led to a shortage of eggs and wholesale prices that are through the roof. Consumers can expect to feel the pain for a while.

Mandatory enhanced biosecurity will now be required and the housing order extended to cover York, North Yorkshire and Shropshire.

An avian flu outbreak in NSW has been eradicated, health authorities say, as the state joins Victoria in lifting restrictions on poultry and egg producers.

Zoonotic transmission of avian influenza viruses into mammals is relatively rare due to anatomical differences in the respiratory tract between species. Recently, clade 2.3.4.4b highly pathogenic H5N1 avian influenza viruses were detected circulating in North American cattle. Sporadic transmission b …

Scientific meetings were canceled, and research data on the bird flu outbreak was delayed, amid confusion over the directive.

H5N1 avian influenza continues to spread amid commercial and backyard poultry, and additional cases have been reported in domestic cats

A team of virologists, infectious disease specialists and pathobiologists affiliated with several institutions in China and the U.K. has found possible evidence that bird flu vaccinations are driving virus evolution. In their study published in the journal Science Advances, the group carried out a genetic analysis of hemagglutinin sequences from avian samples collected between 1996 to 2023.

H5N1 bird flu poses a pandemic threat as CDC identifies 9 alarming mutations enhancing human infection risk Learn about its spread precautions and preventive measures

Learn more about how a vaccine could help prevent the spread of the avian flu virus but may also cause the virus to evolve faster.

India faces a significant risk of an H5N1 bird flu pandemic due to its vast poultry industry, extensive wetlands, and crucial migratory bird flyways. The recent deaths of three tigers and a leopard at a rescue center in Nagpur due to H5N1 have heightened public concern about the virus's spread. H5N1, a highly contagious strain of avian influenza, can infect both animals and humans, posing a severe health threat. Experts warn that the virus's presence in wildlife and its potential to spread to humans could lead to a larger outbreak. India's dense population and close interaction with poultry amplify the risk. Health authorities are urging enhanced surveillance, biosecurity measures in poultry farms, and awareness campaigns to minimize the chances of a pandemic and safeguard public health.
