Cambodia's Ministry of Health recently confirmed the country's twelfth human case of H5N1 avian influenza so far this year.

Reassortment has happened with other influenza viruses. In 2009 , H1N1 – which Shah described as “a close cousin” of H5N1 – was thought to have emerged because of genetic reassortment of ...

Some experts suspect that H5N9 may have emerged among the ducks in California due to genetic reassortment occurring between circulating H5N1 viruses and other flu viruses containing the N9 protein.

For effective human-to-human transmission, genetic reassortment is needed for the virus to adapt to the human host. However, the virus is currently adapted to an avian host, not a mammalian one.

First U.S. detection of virulent H5N9 strain, at a California duck farm, draws scrutiny as evidence of genetic reassortment that could trigger human outbreaks.

An average of one reassortment event for every 31 years in the HA and NA segments was observed, which is considered a low reassortment rate that may be due to differences in genetic compatibility ...

However, were there to be genetic reassortment between H5N1 and a human seasonal flu, that could be a problem. Such a combination might provide the bird flu with the equipment it needs to pass ...

Another tool in an influenza virus’s kit is something known as reassortment. A flu virus’s genetic material is made up of eight RNA segments.

Its genome suggested it had resulted from the genetic reassortment of a mix of flu viruses, including some thought to largely infect pigs and others that originated in birds.

"When a flu virus infects a cell, its genetic material goes in as multiple different segments or pieces," she explained in the video, posted November 18, 2024.

A reassortment containing Oropouche genetic material was found for the first time in Pará, Brazil, and was named Jatobal. A second was detected during an outbreak in Peru: ...
