Named G4 EA H1N1, the virus is similar to the swine flu that caused a pandemic in 2009 and possesses all the essential hallmarks of a candidate pandemic virus, according to the authors of the study.
Scientists at Chinese universities and China's Centre for Disease Control and Prevention (CDC) detected the new virus after analysing 30,000 nasal swabs from pigs in slaughterhouses in 10 Chinese provinces between 2011 and 2018.
