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.

New Delhi, Jul 2: In the midst of India's tense border standoff with China, the defence ministry on Thursday approved procurement of a number of frontline fighter jets, missile systems and other platforms at a cost of Rs 38,900 crore to bolster the combat capability of the armed forces, officials said.

They said 21 MiG-29 fighter jets are being bought from Russia while 12 Su-30 MKI aircraft will be procured from Russia. The ministry has also approved a separate proposal to upgrade existing 59 MiG-29 aircraft.

The decisions were taken at a meeting of the Defence Acquisition Council (DAC) chaired by Defence Minister Rajnath Singh.

The procurement of 21 MiG-29 and upgrading of the existing fleet of MiG-29 are estimated to cost the government Rs 7,418 crore while purchase of 12 new Su-30 MKI from the Hindustan Aeronautics Ltd will be made at a cost of Rs 10,730 crore, the officials said.

The DAC also approved procurement of long-range land-attack cruise missile systems with a range of 1,000 KM and Astra Missiles for Navy and Air Force.

The officials said cost of these design and development proposals is in the range of Rs 20,400 crore.

"While acquisition of Pinaka missile systems will enable raising additional regiments over and above the ones already inducted, addition of long-range land attack missile systems having a firing range of 1000 KM to the existing arsenal will bolster the attack capabilities of the Navy and the Air Force," said a defence ministry official.

"Similarly induction of Astra Missiles having beyond visual range capability will serve as a force multiplier and immensely add to the strike capability of the Indian Navy and the Indian Air Force," he said.
