Washington, Jun 30: Researchers in China have discovered a new type of swine flu that is capable of triggering a pandemic, according to a study published Monday in the US science journal PNAS.

Named G4, it is genetically descended from the H1N1 strain that caused a pandemic in 2009.

It possesses "all the essential hallmarks of being highly adapted to infect humans," say the authors, scientists at Chinese universities and China's Center for Disease Control and Prevention.

The researchers then carried out various experiments including on ferrets, which are widely used in flu studies because they experience similar symptoms to humans -- principally fever, coughing and sneezing. 

G4 was observed to be highly infectious, replicating in human cells and causing more serious symptoms in ferrets than other viruses.

Tests also showed that any immunity humans gain from exposure to seasonal flu does not provide protection from G4.

According to blood tests which showed up antibodies created by exposure to the virus, 10.4 percent of swine workers had already been infected.

The tests showed that as many as 4.4 percent of the general population also appeared to have been exposed.

The virus has therefore already passed from animals to humans but there is no evidence yet that it can be passed from human to human -- the scientists' main worry.

"It is of concern that human infection of G4 virus will further human adaptation and increase the risk of a human pandemic," the researchers wrote.

The authors called for urgent measures to monitor people working with pigs.

"The work comes as a salutary reminder that we are constantly at risk of new emergence of zoonotic pathogens and that farmed animals, with which humans have greater contact than with wildlife, may act as the source for important pandemic viruses," said James Wood, head of the department of veterinary medicine at Cambridge University.

A zoonotic infection is caused by a pathogen that has jumped from a non-human animal into a human.

University of Oxford researchers have claimed that a cheap and widely available drug called dexamethasone can help save the lives of patients who are seriously ill with coronavirus.

Scientists working on the Recovery Trial found the drug could help patients on ventilators and oxygen, but had no effect on those who did not need help breathing.

“Based on these results, one death would be prevented by treatment of around eight ventilated patients or around 25 patients requiring oxygen alone,” researchers said in a statement.

Matt Hancock, the health secretary, tweeted: “This global first exemplifies the power of science.”

“I’m absolutely delighted that today we can announce the first successful clinical trial for a treatment for Covid-19,” Mr Hancock said.

Recovery Trial experts said a randomised group of 2,104 patients was given 6mg of dexamethasone per day for 10 days, while another group of 4,321 were given normal treatment.

Dexamethasone reduced deaths by one-fifth in patients on oxygen feeds and by one-third in those who needed a ventilator to breathe, preliminary results showed.

Mr Hancock added: “This is a huge step forward and it’s because we’ve backed the science.”

Martin Landray, professor of medicine and epidemiology at the Nuffield Department of Population Health, University of Oxford, and one of the trial’s chief investigators, said in a statement: “These preliminary results from the Recovery Trial are very clear – dexamethasone reduces the risk of death among patients with severe respiratory complications.

“Covid-19 is a global disease – it is fantastic that the first treatment demonstrated to reduce mortality is one that is instantly available and affordable worldwide.”

Bengaluru, Jun 20: A petition has been filed in Karnataka High Court to transfer Amulya Leona case to the National Investigation Agency (NIA). She raised pro-Pakistan slogans at an anti-CAA rally on February 20 at Freedom Park.

The petition, filed by advocate Vishal Raghu, blamed the probe team for not filing chargesheet on time and suggested the state government to approach the higher court against bail granted to Amulya Leona.

On June 11, she was granted conditional bail by the Bengaluru civil court.

She was charged with sedition for her actions in the presence of All India Majlis-e-Ittehad-ul-Muslimeen chief Asaduddin Owaisi.

The court granted bail after hearing the bail application. Amulya's advocate on behalf of the petitioner said, "the petitioner is just a 19-year-old lady and she is studying in a private college in the Bengaluru. She shouted 'Pakistan Zindabad' but she never mentioned Pakistan as her country."
