New Virus Threat on Horizon: G4 EA H1N1 Pig Flu

Sharing an Instagram submit about the similar, the actress printed that she won again, a version of the swine flu and it was once the toughest factor she has been via. Thus, systematic surveillance of influenza viruses in pigs is a key measure for predicting the emergence of the next pandemic influenza. "Clearly this situation needs to be monitored very closely". The H1N1 swine flu, on the other hand, infected more than 60 million people in the USA and at least 700 million worldwide, killing an estimated half a million people across the globe.

Because pigs are intermediate hosts for pandemic influenza virus, they form a sort of early warning system. Therefore, "it's necessary to strengthen the surveillance of Chinese pigs for influenza viruses". Of note is the fact that workers aged 18-35 years tested positive at a higher percentage of 20.5%.

Scientists at Chinese universities and China's Centre for Disease Control and Prevention are saying that G4 possesses "all the essential hallmarks of being highly adapted to infect humans".


So far, there is no evidence of human to human transmission.

G4 was noticed to be extremely infectious, they mentioned, replicating in human cells and inflicting extra severe signs in ferrets than different viruses. They collected 30,000 nasal swabs, and from these samples isolated 179 swine flu strains. A strain of influenza virus emerged from the population of pigs in China, named G4-EA-H1N1, a Swine Flu strain, which the scientists said, has the capability of binding to the receptors present in the airway epithelial cells in humans.

As global medical personnel continue their endless battle against SARS-CoV-2, the novel coronavirus that causes COVID-19, virologists and infectious disease specialists are gearing up for a battle against the next potential threat: G4 EA H1N1 swine influenza.


Thailand was the only country in the region that screened out the African Swine Fever which was spreading in many countries and Thai people should not panic about G4 virus reports. "But we must not lose sight of potentially unsafe new viruses". This is one of the most hard things that I have gone through. It was less deadly than initially feared, largely because many older people had some immunity to it - probably because of its similarity to other flu viruses that had circulated years before, scientists said.

Sun Honglei, the paper's first author, says G4's inclusion of genes from the 2009 H1N1 pandemic "may promote the virus adaptation" that leads to human-to-human transmission.
