    Chinese researchers identify new virus with ‘pandemic potential’ (2020/06/30)

    Chinese researchers have found a new strain of swine flu that they believe can trigger the next pandemic. It's been named G4, and it's shown an ability to jump from pigs to humans. According to a paper published in a U.S. scientific journal, the virus was detected in the blood of thousands of farm workers and others in China's hog industry. Researchers warn that this virus is highly capable of mutating to become more contagious and virulent to humans.

    On the heels of the novel coronavirus, a new pathogen has appeared in China. Named G4, this virus is described in the latest issue of the U.S. scientific journal, Proceedings of the National Academy of Sciences. It is carried by pigs and observed to be capable of jumping to people. In addition, it has “all the essential hallmarks” of becoming highly adapted to infecting humans. Experts warn that if ignored, G4 could lead to the next global pandemic.

    The internal genes of G4 are descended from the H1N1 virus of 2009. Its outer envelope is a pig virus, with some avian virus mixed in. These genes have been recombined to create a new virus. Even if you have been infected by H1N1 before, your antibodies would not be effective against this strain. So basically we think that this virus would be able to infect everybody.

    The seasonal resurgence of bird flu is bad enough. G4, with no cure and no vaccine, is the next potential threat to humanity. Scientists suspect that G4 is descended from an H1N1 virus that caused an epidemic in Mexico in 2009. Since 2016, it’s been dominant on Chinese pig farms, with 20.5% of 18- to 35-year-old swine workers infected. If the virus continues to mutate, it may develop the ability to pass from human to human.

    Most of the new infectious diseases that can infect humans originally came from animals. That’s the case now with COVID-19. Therefore keeping a close watch over infectious diseases common to humans and animals is a very important part of disease surveillance.

    The Taiwan Centers for Disease Control says that the scope of the virus’ effects on humans is still unclear. Until more information is available, people are advised to wash their hands thoroughly after touching raw pork, and to cook pork completely to ensure viruses are killed off.
