It is carried by pigs, but it is capable of infecting humans. That is why the researchers are concerned that the world may face another global outbreak if it does not react to the potential threat.
The new strain of the virus that has been identified in China - G4 EA H1N1 - is similar to 2009 swine flu (A/H1N1pdm09), but with some new changes.
According to scientists, it can grow and multiply in the cells that line the human airways.
"Right now we are distracted with coronavirus and rightly so. But we must not lose sight of potentially dangerous new viruses. We should not ignore it," Prof Kin-Chow Chang, who works at Nottingham University in the UK, stated.
As we reported earlier, Scientists from the University of California at San Francisco have found similarities in the structure of coronavirus and cancer.
"The Covid-19 virus causes uneven convex branches to grow in infected cells - an extremely unusual structure that allows the virus to attack several cells at once. Long strands pierce holes in other cells, and the virus passes through the processes from cell to cell," Professor Nevan Krogan, director of the Institute of Quantitative Biological Sciences at the University of California, who led the project, said.
