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.

Bengaluru, Feb 4: A 33-year old woman techie allegedly stabbed her mother to death and made a murderous assault on her younger brother before fleeing their home here, police said on Tuesday.

According to police, the woman fatally stabbed her mother using a knife and attacked the brother early on Monday.

The injured brother has been hospitalised here.

A search was on for the techie and the motive for her action under investigation, police said.

The woman, employed as a software engineer with a company here, earlier had told her mother and 30-year old brother that she has been transferred to Hyderabad and she may have to relocate.

The brother told police that in the early morning on Monday he saw his sister searching something desperately and offered to assist, which she refused.

However, minutes later she made a murderous assault on him, he told police, adding when he screamed for help and called his mother, his sister said she has killed their mother.

She stabbed him and attacked with an iron rod before fleeing, her brother told police.

The body of the mother was found in another room in the house.

"We are still investigating the matter. We are not clear about the motive behind the murder," a police officer told media adding the woman was yet to be arrested.
