Professor Carl Bergstrom at the University of Washington, an outspoken critic of misleading science and author of the book "Calling Bullshit: The Art of Skepticism in a Data-Driven World" has voiced that we are not facing the start of "a double pandemic" of COVID-19 and influenza, despite news headlines that have been suggesting otherwise. G4 was observed to be highly infectious, replicating in human cells and causing more serious symptoms in ferrets than other viruses. Ian M. Mackay, The University of Queensland.

"It is of concern that human infection of G4 virus will further human adaptation and increase the risk of a human pandemic," the researchers wrote.The authors called for urgent measures to monitor people working with pigs. "The work comes as a salutary reminder that we are constantly at risk of new emergence of zoonotic pathogens and that farmed animals, with which humans have greater contact than with wildlife, may act as the source for important pandemic viruses," said James Wood, head of the department of veterinary medicine at Cambridge University.A zoonotic infection is caused by a pathogen that has jumped from a non-human animal into a human.It looks like the email address you entered is not valid.Copyright© Mediacorp 2020.

G4 swine flu viruses in China described in the PNAS report have a mix of genes from influenza viruses found in humans, birds and pigs. SHARE THIS ARTICLE.

The outbreak prompted China to impose strict lockdowns nationwide, closing local and provincial borders and ordering residents to stay at home.The country began reopening in March after largely containing the virus -- but new outbreaks and local transmissions in recent weeks have seen some cities go back under lockdown.

But the G4 virus kept showing up in pigs, year after year -- and even showed sharp increases in the swine population after 2016.Further tests showed that G4 can infect humans by binding to our cells and receptors, and it can replicate quickly inside our airway cells. Named G4, it is genetically descended from the It possesses "all the essential hallmarks of being highly adapted to infect humans," say the authors, scientists at Chinese universities and China's Center for Disease Control and Prevention.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.

We can imagine the virus is a "key" that needs to fit the "lock" on human cells in order to enter them more efficiently and cause robust infections.

Based on laboratory transmission studies in ferrets, G4 viruses can spread via direct contact or via respiratory droplets. "There is no reason for panic and no imminent danger," tweeted Florian Krammer, microbiologist at the Icahn School of Medicine.

Some only showed up one year out of the program's seven, or eventually declined to nonthreatening levels. Dr. Chad Petit, an assistant professor at the University of Alabama at Birmingham, used a "lock and key" analogy in explaining the virus strain during an interview with ABC News. Most were of a new kind that has been dominant among pigs since 2016.
"Until human-to-human spread of this virus occurs, we needn't jump the gun on [developing] yet another vaccine," Dr. Len Horovitz, a pulmonary specialist at Lenox Hill Hospital, told ABC News in an interview. SHARE THIS ARTICLE.
