Double the trouble. Recent papers have shown that the swine flu is making a come back from 2009. All these amid the concurrent COVID-19 pandemic.
According to Chinese universities the novel swine flu is a strain of the H1N1 virus back in the 2009 pandemic. Currently the aforementioned is called the “G4” flu virus.
In a research published Monday, the US-based paper PNAS stated that it has the ability to cause a pandemic.
The authors from China’s Center for Disease Control and Prevention said that it is also a very destructive virus like the COVID-19. They clarified that it has “all the essential hallmarks of being highly adapted to infect humans.”
Within the period of 2011-2018, Chinese researchers have swabbed pigs from slaughterhouses and veterinaries. From 10 provinces of China, they were able to isolate 179 swines with the said virus.

The researchers also conducted other standard experiments on the samples. They saw that in ferrets, they show symptoms like- cough, fever, and colds.
Who is immuned?
From the tests they performed, scientists discovered that the swine flu is highly infectious. They are able to replicate in human cells.
Adding to that, the G4 virus is able to carry out more serious symptoms in ferrets than other viruses.
Based on the studies, it also showed that humans cannot develop immunity to this flu from prior infections.
As a matter of fact, researchers projected that at least 10.4% of slaughter house care takers are now carriers of the virus.
On a grander scale, about 4% of the population has already contracted the said swine flu. Therefore the swine to human transmission has already commenced.
Currently, researchers have yet to discover whether the human transmissions are possible.
Veterinary medicine chief of Cambridge University said that this is a reminder that humans have to lookout for such medical trends.
Chief James Wood said, “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.”
