Centre "Requests" Airlines To Give Passengers Letters On Its Achievements

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.

Mumbai, Mar 9: The mayhem in domestic stock markets deepened with the BSE Sensex falling over 2,400 points and the Nifty50 trading below 10,400 points.

The plunge in the domestic indices was in line with the global markets on persistent fears of economic impact of the coronavirus epidemic.

Stocks of Reliance Industries registered the biggest fall in over 10 years as it fell to Rs 1,094.95 per share. At 1.34 p.m., it was trading at Rs 1,100, lower by Rs 170.05 or 13.39 per cent from its previous close. The stock fell most since October 2008.

The Nifty50 on the National Stock Exchange was trading at 10,314.25 points, lower by 675.20 points or 6.14% from the previous close. 

It was a sell-off across sectors, led by financial, metal, energy and IT stocks - which weighed on the markets.

Further, crude oil prices also slumped around 30% on Monday as Organization of Petroleum Exporting Countries (OEPC) failed to agree on an output cut deal, eventually causing Saudi Arabia to cut its prices as it is likely to increase its production. Saudi Arabia's stance has already raised concerns of an all-out price war.

Brent crude futures are currently trading around $34 per barrel.

On Saturday, Saudi Arabia announced massive discounts to its official selling prices for April, and the nation is reportedly preparing to increase its production above the 10 million barrel per day mark, according to reports.

As per analysts, the oil market witnessed the worst price fall on Monday since the 1991 Gulf War.
