Cambodia's ministry of health has reported its fourth fatal human H5N1 avian flu case of the year, which involves an ...

Researchers identified a novel genotype (D1.1) of highly pathogenic avian influenza H5N1 spreading among wild birds, poultry, ...

A review article published in Nature Reviews Microbiology provides a comprehensive overview of the emergence, global dissemination, genetic diversification, and cross-species transmission of H5 highly ...

The idea is biologically plausible and historically grounded — and it reframes how we think about the origin of pandemics.

sequencing data from circulating avian influenza viruses suggest "ongoing mutations and reassortment/mixing of genomic segments." The widespread viral circulation has apparently affected not only ...

Genetic analysis confirms that a reassortment event in wild birds preceded a single transmission to cattle, after which asymptomatic or presymptomatic cattle facilitated the virus's spread across ...

Because of its segmented pattern, the OROV genome is likely to undergo reassortment and recombination events. The study identified 21 reassortment events (including 17 S-M, 7 S-L, and 11 M-L ...

There are concerns about a more dangerous virus emerging, combining bird flu and seasonal flu in a process called reassortment. “I am very worried about H5N1 in patients that are being treated ...

Another concern is something called reassortment. If an animal or person is infected with two viruses at once, the viruses can trade genetic material, creating something new. This is common in ...
