New swine flu strain with 'pandemic potential' identified in China

It is carried by pigs, but it is capable of infecting humans.

Moreover, the team noted that this virus is "distinct from current human influenza vaccine strains, indicating that preexisting immunity derived from the present human seasonal influenza vaccines can not provide protection".

But she noted that no one knew about the pandemic H1N1 strain, which jumped from pigs to people, until the first human cases surfaced in 2009. Dr. Nelson is an evolutionary biologist at the U.S. National Institutes of Health's Fogarty International Center who studies pig influenza viruses and their spread to humans.

The researchers expressed concern about a virus they called "G4".

Kin-Chow Chang, a professor at Nottingham University in the United Kingdom, said it hasn't posed a big threat so far.

However, he said it is important to monitor the emerging situation.

Researchers have discovered a new strain of flu that could have dramatic repercussions for the world.

Blood sample analysis of workers in the swine industry indicated that almost 10.4 per cent (35/338) of them were positive for the G4 flu virus. Scientists obtained nasal swab samples from more than 30,000 slaughterhouse pigs and veterinary teaching hospitals across 10 China provinces.

The Department of Agriculture (DA) has urged hog raisers to report unsual hog deaths as China reports new flu strain similar to the 2009 swine flu. "Eurasian avian-like swine influenza virus are known to be circulating in the swine population in Asia and to be able to infect humans sporadically", a spokesperson said. Researchers have called it G4 EA H1N1 and say it can be trapped and multiplied in the cells that line the human airway. But we must not lose sight of other potentially unsafe viruses. They further warned that over time, the virus could become better adapted to human hosts and, consequently, become more contagious.

"When they all mix up together and contain some of the elements that might make it susceptible to being transmitted to humans, you always have the possibility that you might have another swine flu-type outbreak as we had in 2009", he said.

"We should not ignore it", he said of the flu strain, even if it's not an immediate problem. And about 510,000 people have died from COVID-19, the disease caused by the virus. According to blood tests, which showed antibodies created by exposure to the virus, 10.4% of pig farmers had already been infected by the virus, and as much as 4.4% of the general population also appeared to have been exposed.

The new study offers but a tiny glimpse into swine influenza strains in China, which has 500 million pigs.
