Another deadly flu has been discovered in China

New type of swine flu named G4, capable of triggering a pandemic has been discovered by Researchers in China, according to a study published Monday in the US science journal PNAS.

It is genetically descended from the H1N1 strain that caused a pandemic in 2009

The World Health Organization said Tuesday that it would "read carefully" the study on the new virus, with a spokesman saying the findings highlighted the importance of the world not letting "our guard down on influenza."

The G4 viruses have become predominant in swine populations in China since 2016. That determination is based on the analysis of 29,918 nasal swabs collected from slaughtered pigs and 1,016 nasal swabs or lung tissues from pigs showing signs of illness, and from its transmission to humans. The results were compared to the genetic sequences of 77 H1N1 variants.
