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, Mar 20: An official of South Western Railway has been suspended for "hiding" her son, who returned from Germany and later tested positive for coronavirus.

The youth has been hiding at a railway guest house in Bengaluru, officials said on Friday.

"She (the railway official) not only failed to inform authorities about her son's return from Germany, but also endangered the lives of others by lodging him in a railway rest house near the main Bangalore railway station," railway spokesperson E Vijaya said.

The Assistant Personnel Officer (Traffic) has been suspended, Vijaya said.

The 25-year-old man, who came from Germany via Spain and was instructed to be in home quarantine after he landed at the Kempegowda International Airport in Bengaluru on March 13, later tested positive for Covid-19 on March 18.

"She virtually hid her son to protect her family but endangered all of us," a South Western Railway official said.

Mangaluru, Mar 28: After a youth from Dakshina Kannada who tested positive for the deadly Covid-19 revealed that he had travelled by a bus, authorities have requested all his fellow passengers to visit their nearest district hospital. 

The 21-year-old man hailing from Belthangady taluk had flown from Dubai to Bengaluru on March 21 and on the same day travelled to Mangaluru by the KSRTC bus bearing registration number KA 19, F3329. 

As he was suffering from fever and cough he was admitted to Puttur government hospital on March 24. He was tested positive for the novel coronavirus on March 27.   

It is not yet know how many passengers were there on board the above mentioned bus which had departed Bengaluru at 4:30 p.m. on March 21. It is believed that most of the passengers who travelled by this bus are residents of Dakshina Kannada. 

Hence, the KSRTC authorities today requested all the passengers who travelled by this bus to visit their nearest district hospital for necessary checkup. The passengers also were urged to quarantine themselves for next couple of weeks.
