THURSDAY, Aug. 5 (HealthDay News) -- The 2009 H1N1 swine flu virus used a new biochemical trick to hijack host cells, a feat that triggered the recent pandemic, according to an international team of scientists.
"We have found why the pandemic H1N1 virus replicated so well in humans," Yoshihiro Kawaoka, a leading influenza expert and a professor of pathobiological sciences at the University of Wisconsin-Madison's School of Veterinary Medicine, said in a university news release.
The H1N1 virus is a combination of four different avian and swine flu viruses that emerged over the past 90 years. It also includes genetic residue of the 1918 pandemic virus that killed as many as 20 million people, Kawaoka explained.
