China brings a new virus threat for the world; The G4 virus

While the entire world is already fighting with the outbreak of the Corona Virus because of the widespread, which was caused in China, the G4 virus from China could be a new threat to the world.

  • 2009’s Pandemic

There has been a discovery of the new swine flu virus, which is Genotype 4 or G4 virus, which is predominant in swine populations since 2016. We have come to know that pigs in China are infected with the G4 virus. The name of the G4 virus genetically descended from the H1N1 strain, and the Pandemic in 2009 was caused by the same.

American Centers for Disease Control and Prevention concludes that the 2009 H1N1 pandemic was different as people older than 60 had developed antibodies against the virus. Still, the people younger than 60 were more vulnerable to the illness. The CDC estimated that 1,51,700-5,75,400 people worldwide died from (H1N1) virus infection in the first year.

  • Swine population

Pigs are the only mammal species that are vulnerable to both avian and human influenza viruses because they have receptors for both kinds of illnesses.

This virus is of great concern for the people who rear or eat pork as this virus is capable of transmitting from the pigs to the humans, and it can trigger a global pandemic. Pig farms might add the widespread circulation of G4 viruses in pigs, “inevitably increases their exposure to humans.” This was a study that was published in the US Science Journal.

• Transmission of the virus

Soon, you may have to ask the people which Pandemic is referring to because genotype four can become a pandemic in 2020. The virus can replicate in the outer layer of the respiratory system and starts multiplying rapidly in the human cells. Luckily, there has been no evidence of human to human transmission until now, despite five years of extensive exposure. But the virus could be transmitted from swine to any human, and it would lead to very severe infection and can even cause death. Therefore, it is necessary to strengthen the efforts made to cease the widespread of G4 viruses among swine and human populations.

  • What did the tests reveal? 

This virus is dominant among the workers in the swine industry. 10.4 percent of swine workers have already been infected with this virus. Tests also revealed that 4.4% of the general population had been exposed to the virus. The scientists said that recent cases of G4 virus infection were reported in 2016 and 2019, were of a 46- and a nine-year-old, respectively, and these two had neighbors who reared pigs.

  • Symptoms of G4 virus 

Even the experiment on ferret shows that there were severe symptoms of the virus. Various tests that were demonstrated concluded that the G4 virus could efficiently infect the ferrets causing clinical symptoms in them like wheezing, coughing, and weight loss ranging from 7.3 to 9.8 percent of the mammals’ body mass and sneezing. Ferrets experience some similar symptoms in humans, such as cough, sneezing, and fever. People between the age of 18 and 35 have had about 20 percent of favorable rates of this virus.

  • There has been no immunity against the G4 virus yet. 

And even the tests prove that humans are not protected from the highly infectious virus because of any pre-existing immunity gained from other humans.

“It is less likely that this particular virus is going to cause a pandemic is low,” says Martha Nelson, who studies pig influenza viruses in the United States and their spread to humans. Nelson commented that we would have to produce a human G4 vaccine, but this is a process that would require significant funding. This virus is concerning as humans have no immunity to this avian influenza virus. It seems as if this year is a year of viruses and pandemics. All we can do is take precautions not to get affected by any of the viruses.
